Advanced Part Table of ContentIntroductionGit TerminologiesSetup of Git and Github on SystemConcept of Github and GitStagingBeginner commands of GitMerging ConflictsResolving ConflictsSome Practices to avoid ConflictsPull RequestAdvanced Git Commands Important Note Hello fellow readers this is a going to be third part of the series Git and GitHub Tutorial Beginner to Advanced Are you a new reader Here s the link to previous parts of the series Part Part Ok now let s move forward with the topic without wasting anymore moments Merging Conflicts I know most of you guys are familiar with merging and is even familiar with the command that is used to merge two branches Now s lets dig a little bit deeper over the topic I can guarantee you it would worth it While merging of two branches there are two types of scenario s that occur No Conflicts In this case the changes are on different files so Git is not confused about merging them and Auto merging is done by Git itself Output Merge made by the recursive strategy src components testComponent js file changed insertion deletion Conflicts In this case two developers ‍have edited the same file with two different things Due to this reason when the merge is done it is landing into a conflict as Git can t understand which changes are meant to be kept and which ones to be discarded But don t worry Git is a smart system and it knows it needs to ask the user in such cases Let s see how it looks Output On terminal Auto merging src App jsCONFLICT content Merge conflict in src App jsAutomatic merge failed fix conflicts and then commit the result On Editor Resolving Conflicts Now that you have faced a conflict on the codebase let s learn how to fix the same Note I am using VS Code while taking some screenshots If you are on a different code editor it may vary a bit The editor is just a tool so don t worry too much if you are on a different one the concepts are important and all other things would be same There are two ways to fix this Manual let s take the adverse case for an instance that someone is using notepad for coding I know that s somewhat funny but for that person the editor would not make things easier ‍ ️ Here s the format of the conflict through git on codebase lt lt lt lt lt lt lt Your current branch current branch code merging branch code gt gt gt gt gt gt gt Merging branchJust select the one you want to keep and remove the others Let s take you want to go with the current branch code So change this to current branch code Using Editor If you are using a good editor than your editor would be helping you fixing such conflicts Let s see a demo image how it looks on an editor The files which have conflicts are at Staged changes so you can either list them or see all the files which are Red colored to get an idea of those files with conflicts Secondly with the use of those buttons you can select the code of which branch you want to move forward with and it would remove all other unnecessary stuffs for you on it s own As you are done with removing all such things just add all the files with git add and then same procedure of commit and push git commit m commit message git push Some Practices to avoid Conflicts Facing too many conflicts on a codebase can be a tiring task to handle Here s some good practices to avoid such conflicts which would make your life easier Try to follow microservice model for big projects Make use of some framework to reduce reductant code and for getting controllers middleware web bundle etc Try to divide the work properly so no two developers find the need of working on same file A good and active communication are always important which helps in resolving or avoiding such conflicts very easily I know this section is something which most of you guys will think as not so important but which you would be working over a codebase you will know why we need such stuffs Pull Request I know some people would have heard it quite frequently while working in a company or open source projects In case you haven t don t worry I am here to introduce you to this concept Let s try to understand it through a diagram While working in a organization there need some control over what things can go to the important branches Like dev branch which is mostly second important branch where all the things related to next release are integrated Main branch is one of the branch that organization uses for CI CD pipeline with their hosted website So anything in that branch will go live in front of the users So yes only some people should be able to push any code to these critical branches Otherwise things can go very bad That s where Pull Request PR comes into play Every developer when they want to merge their code with any of these critical branches They make a pull request through GitHub GUI and the authenticated person will check all the code and if it is correct allows the merge to happen Let s see how to create one Pull Request through GitHub GUI Go to GitHub gt Repository gt Pull Request gt New Pull RequestSelect both branches Format To lt From gt Create Pull RequestWrite PR title gt PR Explanation It s important gt Create Pull RequestBonus Step Conflict on Pull Request Are you are reviewer And got a PR like this Worry not let s cover this issue for you so that you can work without any worries To fix this use these command GitHub GUI will not help you here Commands git checkout base branch of PRgit merge compare branch of PR solve conflicts as discussed in merging conflicts git push Advanced Git Commands I know many people were waiting for this set of cheat sheets So here we are Create and Checkout Branch Single CommandNow you know all the beginner commands to do the same Why not speedup this process with a single command git checkout b lt name of branch gt Output Switched to a new branch name of branch Command to list all recent worked branchesNow you know all the beginner commands to do the same Why not speedup this process with a single command git for each ref count sort committerdate refs heads format refname short Output testbranchtestbranchmaintestbranchfeat Delete origin with no RemotesMany times we have a branch deleted from the repository but we didn t noticed it and it s local reference is still there Use this to delete them in one go git fetch pruneOutput No Output Delete all Local and Remote branchesAre you done with a project Want to clear all branches and local code stored on it Use this git reset hardOutput No Output Logs of GitWant to get a view of all the

海外TECH	DEV Community	Crear una aplicación para subir images - React y Cloudinary ⚛️.	https://dev.to/franklin030601/crear-una-aplicacion-para-subir-images-react-y-cloudinary--1h5f	Crear una aplicación para subir images React y Cloudinary ️ ÍndiceIntroducción Primeros pasos Configurando Cloudinary Creando el proyecto con create react app Creando el componente de titulo Creando el componente de Drag amp Drop Creando el componente de Box Drag amp Drop Creando el componente de Image Selected Llenando el componente con funciones y estado Agregando la funcionalidad para subir imágenes a Cloudinary Mostrar link de la imagen subida a Cloudinary Ocultar link de la imagen después de unos segundos Introducción Introducción Esta aplicación consiste en una interfaz donde se podrán subir imágenes mediante Drag amp Drop y dicha imagen se guardara en Cloudinary El enlace al código esta al final de este post Primeros pasos Configurando Cloudinary Iniciar sesión en Cloudinary o crearte una cuenta En el Dashboard te aparcera el nombre de tu nube deberás guardarlo en un bloc de notas o algo ya que lo usaremos después Presionar el icono de engrane que te llevara a la configuración Seleccionar la pestaña upload Bajar hasta donde dice “Upload presets Presionar el enlace que dice “Add upload preset Donde dice “Upload preset name en la caja de texto colocar un nombre para ese preset ej ztzhkz deberás guardarlo en un bloc de notas o algo ya que lo usaremos después Donde dice “Signing Mode seleccionar UnsignedPresionar el botón save se encuentra en la parte superior de la pagina para guardar preset Creando el proyecto con create react app Necesitamos crear un nuevo proyecto de React En este caso lo hare con la herramienta de create react app usando TypeScript npx create react app upload image app template typescriptLuego de haberse creado nos dirigimos al proyecto lo abrimos con el editor de cogido de preferencia En mi caso Visual Studio Code cd upload image app amp amp code Ahora necesitaremos instalar un paquete de terceros llamado react images uploading el cual nos ayudara a trabajar la acción de Drag amp Drop con las imágenes npm install react images uploading Creando el componente de titulo Dentro de la carpeta src components creamos el archivo Title tsx Y agregamos el siguiente código import React from react export const Title gt return lt gt lt div className container blob gt lt SVG gt lt div gt lt h className title gt lt span gt Upload image lt span gt lt br gt lt span gt with lt span gt lt br gt lt span gt React amp Cloudinary lt span gt lt h gt lt gt const SVG gt return lt svg className svg blob viewBox xmlns gt lt path d M C C C C C C C C C C Z transform translate gt lt svg gt Después nos dirigimos al archivo src App tsx y borramos todo para agregar lo siguiente import React from react import Title from components const App gt return lt div className container grid gt lt Title gt lt div gt export default AppPara la parte de los estilos pueden revisar mi código que esta en GitHub esto lo hago para que el articulo no se haga tan largo y solo concentrarme en la parte importante Creando el componente de Drag amp Drop Dentro de la carpeta src components creamos un archivo llamado DragAndDrop tsxPrimero haremos uso del estado para manejar el comportamiento del componente cuando se seleccione alguna imagen o se arrastre y suelte la imagen dentro del componente El componente ImageUploading le colocamos los siguientes propiedades multiple →en false para solo seleccionar una imagen a la vez maxNumber →en ya que solo aceptaremos una imagen value →un valor de tipo ImageListType Le pasamos el valor del estado “images onChange →un método que se ejecuta cuando cuando se selecciona una imagen este método recibe dos parámetros pero a nosotros solo nos importa el primero el cual es un array de objetos que contiene la información de la imagen seleccionada Le pasamos la función handleChange dicha función actualiza el estado agregando la imagen seleccionada al estado import React useState from react import ImageUploading ImageListType from react images uploading export const DragAndDrop gt const images setImages useState lt ImageListType gt const handleChange imageList ImageListType gt setImages imageList return lt gt lt ImageUploading multiple false maxNumber value images onChange handleChange gt lt ImageUploading gt lt gt El componente ImageUploading recibe un función como hijo dicha función nos da acceso a ciertas parámetros de los cuales usaremos los siguientes ImageList →un valor de tipo ImageListType que nos trae un arreglo de las imágenes que se han seleccionado en este caso solo debe ser una imagen seleccionada por lo cual siempre apuntaremos a la posición ejemplo imageList dragProps →es un conjunto de métodos que nos ayudaran a realizar la acción de Drag amp Drop isDragging →retorna true si se esta arrastrando una imagen al componente de lo contrario se queda en false onImageUpload →Método que al ejecutarse abre el explorador de archivos del dispositivo para seleccionar una imagen onImageRemove →Método que recibe un índice de la imagen que se quiere quitar y la remueve de la lista que en este caso siempre sera el índice onImageUpdate →Método que recibe un índice de la imagen que se quiere actualizar que en este caso siempre sera el índice y abre el explorador de archivos para seleccionar una nueva imagen lt ImageUploading multiple false value images onChange handleChange maxNumber gt imageList onImageUpload dragProps isDragging onImageRemove onImageUpdate gt lt ImageUploading gt Creando el componente de Box Drag amp Drop La función dentro del componente lt ImageUploading gt debe retornar JSXDentro de la carpeta src components creamos un archivo llamado BoxDragAndDrop tsxEste componente es donde se haráel drag amp drop o se daráclick para seleccionar alguna imagenAgregamos el siguiente código import React from react interface Props onImageUpload gt void dragProps any isDragging boolean export const BoxDragAndDrop isDragging onImageUpload dragProps Props gt return lt div onClick onImageUpload dragProps className container dnd center flex isDragging isDragging gt lt span className label dnd gt Chosee an Image or Drag and Drop an Image lt span gt lt div gt Luego agregamos el componente BoxDragAndDrop tsx en el componente DragAndDrop tsxDentro de la función haremos una condicional dependiendo de la lista de imágenes si esta vacía debe mostrar el componente BoxDragAndDrop tsx sino significa que ya hay una imagen seleccionada y debe mostrar dicha imagen lt ImageUploading multiple false value images onChange handleChange maxNumber gt imageList onImageUpload dragProps isDragging onImageRemove onImageUpdate gt lt gt imageList lt p gt SELECTED IMAGE lt p gt lt BoxDragAndDrop onImageUpload dragProps isDragging gt lt gt lt ImageUploading gt En el componente BoxDragAndDrop tsx se nota tal vez una sintaxis rara es una forma diferente de pasar propiedades solo lo hice para ahorrar un par de lineas Aunque si es difícil de leer puedes optar por la otra forma lt BoxDragAndDrop dragProps dragProps isDragging isDragging onImageUpload onImageUpload gt Creando el componente de Image Selected Dentro de la carpeta src components creamos un archivo llamado ImageSelected tsxEste componente mostrara la imagen que se ha seleccionado asícomo botones los cuales servirán para Subir la imagen a CloudinaryRemover la imagen seleccionadaActualizar la imagen seleccionada Agregamos el siguiente código import React from react interface Props loading boolean img string onUpload gt Promise lt void gt onImageRemove index number gt void onImageUpdate index number gt void export const ImageSelected img loading onUpload onImageRemove onImageUpdate Props gt return lt div gt lt img className image selected src img alt image selected width gt lt div className container buttons gt loading lt p className loading label gt Upload image lt p gt lt gt lt button disabled loading onClick onUpload gt Upload lt button gt lt button disabled loading onClick gt onImageUpdate gt Update ️ lt button gt lt button disabled loading onClick gt onImageRemove gt Cancel lt button gt lt gt lt div gt lt div gt Este componente recibe parámetros img →la imagen seleccionada que se mostraráen pantallaloading →valor booleano que indicara cuando la imagen este siendo cargada a Cloudinary onUpload →Método el cual se encargara de subir la imagen a Cloudinary se explica más a detalle a continuación onImageRemoveonImageUpdateLuego agregamos el componente ImageSelected tsx en el componente DragAndDrop tsxLes marcara error ya que le faltan los parámetros que son obligatorios por lo que los tenemos que crear lt ImageUploading multiple false value images onChange handleChange maxNumber gt imageList onImageUpload dragProps isDragging onImageRemove onImageUpdate gt lt gt imageList lt ImageSelected gt lt BoxDragAndDrop onImageUpload dragProps isDragging gt lt gt lt ImageUploading gt Llenando el componente con funciones y estado En el componente DragAndDrop tsx necesitaremos agregar un nuevo estado para manejar el loading y otro estado para agregar la URL que la imagen ya guardada en cloudinary Agregamos la función onUpload que por el momento no hace nada aún export const DragAndDrop gt const images setImages useState lt ImageListType gt const urlImage setUrlImage useState const loading setLoading useState false const handleChange imageList ImageListType gt setImages imageList const onUpload gt return lt gt lt ImageUploading multiple false value images onChange handleChange maxNumber gt imageList onImageUpload dragProps isDragging onImageRemove onImageUpdate gt lt gt imageList lt ImageSelected gt lt BoxDragAndDrop onImageUpload dragProps isDragging gt lt gt lt ImageUploading gt lt gt Después ya podemos pasarle los parámetros al componente lt ImageSelected gt El parámetro img se obtiene de la propiedad imageList en la posición accediendo a la propiedad dataURL lt ImageSelected img imageList dataURL onImageRemove onUpload onImageUpdate loading gt Agregando la funcionalidad para subir imágenes a Cloudinary Antes de ir al método onUpload debemos prepara la función para hacer la llamada a la API de cloudinary Para ello creamos la carpeta src utils y dentro creamos el archivo fileUpload ts y agregamos lo siguiente Creamos la función asíncrona fileUpload que recibe una imagen de tipo File y retorna un string que sera la URL de la imagen o null Aquíharemos uso de los datos que configuramos en cloudinary anteriormente el nombre de la nube y el preestablecido Sera mejor colocar dichos valores en variables de entorno ya que son delicadas const cloud name process env REACT APP CLOUD NAME const preset process env REACT APP PRESET const cloud name example cloud name const preset example preset export const fileUpload async file File Promise lt string null gt gt Luego construimos la URL para hacer la llamada a la API const cloud name example cloud name const preset example preset export const fileUpload async file File Promise lt string null gt gt const cloudinaryUrl cloud name image upload const formData new FormData formData append upload preset preset formData append file file try const res await fetch cloudinaryUrl method POST body formData if res ok return null const data await res json return data secure url catch error return null Luego construimos la data que vamos enviar a la API en este caso la imagen const cloud name example cloud name const preset example preset export const fileUpload async file File Promise lt string null gt gt const cloudinaryUrl cloud name image upload const formData new FormData formData append upload preset preset formData append file file Finalmente hacemos uso de la API fetch para hacer la petición y mandar la data Si la respuesta no es correcta retornamos null y si no retornamos la URL de la imagen const cloud name example cloud name const preset example preset export const fileUpload async file File Promise lt string null gt gt const cloudinaryUrl cloud name image upload const formData new FormData formData append upload preset preset formData append file file try const res await fetch cloudinaryUrl method POST body formData if res ok return null const data await res json return data secure url catch error return null Ahora sí es hora de usar la función que acabamos de crear Primero colocamos el loading en true Hacemos la llamada a la función fileUpload y le mandamos el valor del estado recordando que es un arreglo de ImageListType asíque accedemos a la posición a la propiedad file Luego colocamos el loading en false Evaluamos si la URL no es null Si No es nula actualizamos el estado y guardamos esa URL Si es nula mandamos una alerta de Error Finalmente vaciamos el estado de las imagen seleccionada const onUpload async gt setLoading true const url await fileUpload images file setLoading false if url setUrlImage url else alert Error please try again later setImages Mostrar link de la imagen subida a Cloudinary Dentro de la carpeta src components creamos un archivo llamado Message tsxEl cual recibe la URL de la imagen que puede ser null o un string import React from react interface Props urlImage string null export const Message urlImage Props gt return lt gt urlImage amp amp lt span className url cloudinary sumbit gt Your Image uploaded successfully lt a target blank href urlImage gt View Image lt a gt lt span gt lt gt Luego agregamos el componente Message tsx en el componente DragAndDrop tsx y le pasamos el valor del estado de urlImage return lt gt lt Message urlImage urlImage gt lt ImageUploading multiple false value images onChange handleChange maxNumber gt imageList onImageUpload dragProps isDragging onImageRemove onImageUpdate gt lt gt imageList lt ImageSelected onImageRemove onImageUpdate onUpload loading img imageList dataURL gt lt BoxDragAndDrop onImageUpload dragProps isDragging gt lt gt lt ImageUploading gt lt gt Ocultar link de la imagen después de unos segundos El en componente DragAndDrop tsx agregaremos un efecto Lo que haráes que después de segundos pondráel valor del estado de urlImage en string vacío lo que haráque no se cree debido a la condicional useEffect gt let timeout NodeJS Timeout if urlImage timeout setTimeout gt setUrlImage return gt clearTimeout timeout urlImage Refactorizando el componente Drag amp Drop y creando un custom hook Hay demasiada lógica en el componente la cual podemos colocar en un custom hook Para ello creamos la carpeta Dentro de la carpeta src hooksDentro de esa carpeta creamos el archivo useUploadImage ts y movemos la lógica dentro de este hook import useEffect useState from react import ImageListType from react images uploading import fileUpload from utils export const useUploadImage gt const images setImages useState lt ImageListType gt const loading setLoading useState false const urlImage setUrlImage useState const handleChange imageList ImageListType gt setImages imageList const onUpload async gt setLoading true const url await fileUpload images file setLoading false if url setUrlImage url else alert Error please try again later setImages useEffect gt let timeout NodeJS Timeout if urlImage timeout setTimeout gt setUrlImage return gt clearTimeout timeout urlImage return loading onUpload handleChange urlImage images Y de esta manera nos quedaría el componente DragAndDrop tsxNota que al componente ImageSelected le quitamos las propiedades loading y onUpload y le pasamos …rest import React from react import ImageUploading from react images uploading import useUploadImage from hooks import ImageSelected BoxDragAndDrop Message from export const DragAndDrop gt

海外TECH	DEV Community	Build a GraphQL app in Node.js with TypeScript and graphql-request	https://dev.to/logrocket/build-a-graphql-app-in-nodejs-with-typescript-and-graphql-request-l19	Build a GraphQL app in Node js with TypeScript and graphql requestWritten by Hussain Arif️In this article you will build a full stack app using GraphQL and Node js in the backend Meanwhile our frontend will use the graphql request library to perform network operations on our backend We will cover the following steps Why use graphql request and TypeScript Building our server Project initialization Creating our database Defining our schema Creating resolvers Configuring our server Creating mutations Building our client Creating query variables Performing queries Performing mutations Why use graphql request and TypeScript Whenever developers build a GraphQL server using Apollo the library generates a “frontend which looks like so This interface allows users to make query or mutation requests to the server via code However let s address the elephant in the room it doesn t look very user friendly Since the frontend doesn t feature any buttons or any helpful interface elements it might be hard for many users to navigate around your app Consequently this shrinks your user base So how do we solve this problem This is where graphql request comes in It is an open source library which lets users perform queries on a GraphQL server It boasts the following features Lightweight ーThis library is just over kilobytes minified which ensures your app stays performant Promise based API ーThis brings in support for asynchronous applications TypeScript support ーgraphql request is one of many libraries which allows for TypeScript One major advantage of Typescript is that it allows for stable and predictable codeFor example look at the following program let myNumber here myNumber is an integermyNumber hello now it is a string myNumber myNumber even though we are adding a string to an integer JavaScript won t return an error In the real world it might bring unexpected outputs However in Typescript we can tell the compiler what data types we need to choose let myNumber number tell TS that we want to declare an integer myNumber hello returns an error Therefore it s easier to debug the program this promises stability and security In this article we will build a full stack app using GraphQL and TypeScript Here we will use the apollo server express package to build a backend server Furthermore for the frontend we will use Next and graphql request to consume our GraphQL API Building our server Project initializationTo initialize a blank Node js project run these terminal commands mkdir graphql ts tutorial create project folder cd graphql ts tutorial npm init y initialize the appWhen that s done we now have to tell Node that we need to use TypeScript in our codebase configure our Typescript npx tsc init rootDir app outDir dist esModuleInterop resolveJsonModule lib es module commonjs allowJs true noImplicitAny truemkdir app our main code foldermkdir dist Typescript will use this folder to compile our program Next install these dependencies development dependencies Will tell Node that we will use Typescriptnpm install d ts node types node typescript types express nodemon Installing Apollo Server and its associated modules Will help us build our GraphQL servernpm install apollo server express apollo server core express graphqlAfter this step navigate to your app folder Here create the following files index ts Our main file This will execute and run our Express GraphQL server dataset ts This will serve as our database which will be served to the client Resolvers ts This module will handle user commands We will learn about resolvers later in this article Schema ts As the name suggests this file will store the schematics needed to send data to the clientIn the end your folder structure should look like so Creating our databaseIn this section we will create a dummy database which will be used to send requested data To do so go to app dataset ts and write the following code let people id number name string id name Cassie id name Rue id name Lexi export default people First we created an array of objects called people This array will have two fields id of type number and name of type string Defining our schemaHere we will now create a schema for our GraphQL server To put it simply a GraphQL schema is a description of the dataset that clients can request from an API This concept is similar to that of the Mongoose library To build a schema navigate to the app Schema ts file There write the following code import gql from apollo server express will create a schemaconst Schema gql type Person id ID name String handle user commands type Query getAllPeople Person will return multiple Person instances getPerson id Int Person has an argument of id of type Integer export default Schema export this Schema so we can use it in our projectLet s break down this code piece by piece The Schema variable contains our GraphQL schema First we created a Person schema It will have two fields id of type ID and name of type String Later on we instructed GraphQL that if the client runs the getAllPeople command the server will return an array of Person objects Furthermore if the user uses the getPerson command GraphQL will return a single Person instance Creating resolversNow that we have coded our schema our next step is to define our resolvers In simple terms a resolver is a group of functions that generate response for a GraphQL query In other words a resolver serves as a GraphQL query handler In Resolvers ts write the following code import people from dataset get all of the available data from our database const Resolvers Query getAllPeople gt people if the user runs the getAllPeople command if the user runs the getPerson command getPerson any args any gt console log args get the object that contains the specified ID return people find person gt person id args id export default Resolvers Here we created a Query object that handles all the incoming queries going to the server If the user executes the getAllPeople command the program will return all the objects present in our database Moreover the getPerson command requires an argument id This will return a Person instance with the matching ID In the end we exported our resolver so that it could be linked with our app Configuring our serverWe re almost done Now that we have built both our schema and resolver our next step is to link them together In index js write this block of code import ApolloServer from apollo server express import Schema from Schema import Resolvers from Resolvers import express from express import ApolloServerPluginDrainHttpServer from apollo server core import http from http async function startApolloServer schema any resolvers any const app express const httpServer http createServer app const server new ApolloServer typeDefs schema resolvers tell Express to attach GraphQL functionality to the server plugins ApolloServerPluginDrainHttpServer httpServer as any await server start start the GraphQL server server applyMiddleware app await new Promise lt void gt resolve gt httpServer listen port resolve run the server on port console log Server ready at http localhost server graphqlPath in the end run the server and pass in our Schema and Resolver startApolloServer Schema Resolvers Let s test it out To run the code use this Bash command npx nodemon app index ts This will create a server at the localhost graphql URL Here you can see your available schemas within the UI This means that our code works All of our GraphQL queries will go within the Operation panel To see it in action type this snippet within this box make a query query get all of the people available in the server getAllPeople procure their IDs and names id name To see the result click on the Run button We can even search for a specific entity via the getPerson query query getPersonId Int the argument will be of type Integer getPerson id get the person with the ID of name id Creating mutationsIn the GraphQL world mutations are commands that perform side effects on the database Common examples of this include Adding a user to the database ーWhen a client signs up for a website the user performs a mutation to save their data in their database Editing or deleting an object ーIf a user modifies or removes data from a database they are essentially creating a mutation on the serverTo handle mutations go to your Schema ts module Here within the Schema variable add the following lines of code const Schema gql other code type Mutation the addPerson commmand will accept an argument of type String it will return a Person instance addPerson name String Person Our next step is to create a resolver to handle this mutation To do so within the Resolvers ts file add this block of code const Resolvers Query further code code to add all our mutations go here Mutation create our mutation addPerson any args any gt const newPerson id people length id field name args name name field people push newPerson return newPerson return the new object s result The addPerson mutation accepts a name argument When a name is passed the program will create a new object with a matching name key Next it will use the push method to add this object to the people dataset Finally it will return the new object s properties to the clientThat s it To test it out run this code within the Operations window perform a mutation on the servermutation name String addPerson name Hussain add a new person with the name Hussain if the execution succeeds return its id and name to the user id name Let s verify if GraphQL has added the new entry to the database query getAllPeople get all the results within the people database return only their names name Building our clientWe have successfully built our server In this section we will build a client app using Next that will listen to the server and render data to the UI As a first step initialize a blank Next js app like so npx create next app latest graphql client tstouch constants tsx our query variables go here To perform GraphQL operations we will use the graphql request library This is a minimal open source module that will help us make mutations and queries on our server npm install graphql request graphqlnpm install react hook form to capture user input Creating query variablesIn this section we will code our queries and mutations to help us make GraphQL operations To do so go to constants tsx and add the following code import gql from graphql request create our queryconst getAllPeopleQuery gql query getAllPeople run the getAllPeople command id name Next declare a mutationconst addPersonMutation gql mutation addPeople name String addPerson name name add a new entry Argument will be name id name export getAllPeopleQuery addPersonMutation In the first part we created the getAllPeopleQuery variable When the user runs this query the program will instruct the server to get all the entries present in the database Later on the addPerson mutation tells GraphQL to add a new entry with its respected name field In the end we used the export keyword to link our variables with the rest of the project Performing queriesIn pages index ts write the following code import type NextPage GetStaticProps InferGetStaticPropsType from next import request from graphql request allows us to perform a request on our serverimport getAllPeopleQuery from constants import Link from next link const Home NextPage result extract the result prop InferGetStaticPropsType lt typeof getStaticProps gt gt return lt div className styles container gt result map item any gt render the result array to the UI return lt p key item id gt item name lt p gt lt Link href addpage gt Add a new entry lt Link gt lt div gt fetch data from the serverexport const getStaticProps GetStaticProps async gt the first argument is the URL of our GraphQL server const res await request http localhost graphql getAllPeopleQuery const result res getAllPeople return props result will be passed to the page component as props export default Home Here is a breakdown of this code piece by piece In the getStaticProps method we instructed Next to run the getAllPeople command on our GraphQL server Later on we returned its response to the Home functional component This means that we can now render the result to the UI Next the program used the map method to render all of the results of the getAllPeople command to the UI Each paragraph element will display the name fields of each entry Furthermore we also used a Link component to redirect the user to the addpage route This will allow the user to add a new Person instance to the tableTo test out the code run the following terminal command npm run devThis will be the result Our GraphQL server even updates in real time Performing mutationsNow that we have successfully performed a query we can even perform mutations via the graphql request library Within your pages folder create a new file called addpage tsx As the name suggests this component will allow the user to add a new entry to the database Here start by writing the following block of code import type NextPage GetStaticProps InferGetStaticPropsType from next import request from graphql request import addPersonMutation from constants const AddPage NextPage gt return lt div gt lt p gt We will add a new entry here lt p gt lt div gt export default AddPage In this piece of code we are creating a blank page with a piece of text We are doing this to ensure whether our URL routing system works This means that we used routing successfully Next write this snippet in your addpage tsx file import useForm from react hook form const register handleSubmit useForm if the user submits the form then the program will output the value of their input const onSubmit data any gt console log data return lt div gt lt form onSubmit handleSubmit onSubmit gt Bind our handler to this form The user s input will be saved within the name property lt input defaultValue test register name gt lt input type submit gt lt form gt lt div gt This will be the output Now that we have successfully captured the user s input our last step is to add their entry to the server To do so change the onSubmit handler located in pages addpage tsx file like so const onSubmit async data any gt const response await request http localhost graphql addPersonMutation data console log response Here we re performing a mutation request to our GraphQL server via the request function Furthermore we also passed in the addPerson mutation command to our request header This will tell GraphQL to perform the addMutation action on our serverThis will be the result And we re done ConclusionHere is the full source code of this project In this article you

海外TECH	DEV Community	Go from the beginning - working with loops	https://dev.to/itnext/go-from-the-beginning-working-with-loops-4lpa	Go from the beginning working with loops Go from the beginning working with loopsTLDR this article covers working with loops in GoYou are likely to want to repeat a set of instructions For example you might have a list of orders where you need to process each order Or you have a file that you need to read it line by line or there might be some other calculation Regardless of your situation you are likely to need a looping construct so what are your options in Go You are using the for loop There are three major ways you can use it increment steps With the help of a variable you define a start point a condition when to stop and an incrementation step This is your classic for loop Here s what it looks like for i i lt i run these statements while In many programming languages you a have a while keyword Go doesn t have that but what you can do is to use the for loop in a similar way You omit the initialization step and increment step and get this code for lt condition gt run these statements for each lastly you have the for each like construct that operates on an array like sequence It uses the range keyword to function for i s range array run these statements SeriesYour first programVariablesIf and elseConversionsLoops you are hereUser inputFunctionsError handling The for loopThe conventional for loop has three distinct parts initialization here you want to create a variable and assign it a starter value like so for i Note the use of you usually don s use semicolon but for this construct you need it condition The next step is evaluating whether you should continue incrementing or not You define a boolean expression here that if true continues to loop for i i lt i lt as long as a value is between and becomes then loop breaks then it returns true and the loop continues increment in this step the loop variable i is updated updating it by is common but you can add any increment size negative or positive for i i lt i Here i is updated by This loop will run ten times Repeat until condition is met with whileA simplified version of this loop can omit the initialization and increment step You are then left with the condition step only This step tests whether a variable is true or false and the loop exits on false Here s an example i for i lt i do something In this case we are declaring i outside of the loop Within the loop we need to change the value to something that will make the loop expression evaluate to false or it will loop forever Here s another code using the same idea but this time we ask for input from the user var keepGoing true answer for keepGoing fmt Println Type command fmt Scan amp answer if answer quit keepGoing false fmt Println program exit An example run of the program could look like so Type command testType command somethingType command quitprogram exit Using for each over a rangeFor this next loop construct the idea is to operate over an array or some kind of known sequence For each iteration you are able to get the index as as well as the next item in the loop Here s some example code arr string arg arg arg for i s range arr fmt Printf index d item s n i s arr is defined as an array and then the range construct is used to loop over the array For each iteration the current index is being assigned to i and the array item is assigned to s An output of the above code will look like so index item argindex item argindex item arg Controlling the loop with continue and breakSo far you ve seen three ways you can use the for construct There are also ways to control the loop You can control the loop with the following keywords break this will exit the loop construct arr int for i i lt i fmt Println arr i if arr i lt break The output will be it won t output as the loop exits after the first iteration continue this will move on to the next iteration If break exits the loop continue skips the current iteration arr int for i i lt i if arr i lt break fmt Println arr i The output will be SummaryYou ve learned that there s a for loop You can use a for loop when you want to repeat a set of instructions There are three approaches you can use in Go that this article just covered	2022-06-09 14:33:11
海外TECH	DEV Community	How to use variables in CSS with v-bind in VueJs 3	https://dev.to/zelig880/how-to-use-variables-in-css-with-v-bind-in-vuejs-3-802	How to use variables in CSS with v bind in VueJs Frontend frameworks like VueJs React and Svelte offer great flexibility in the development of UI components The simplicity in which we can create components with dynamic properties offers the possibility to solve complex requirements with just a few lines of code If you have been using VueJs you are probably aware of the limitation that prevented you to use props data and computed properties within your component styles Developers had to resort to the use of hacks to make styles dynamic usually at the cost of more verbose code and untidy code Since the release of VueJs we have a built in solution that allows us the use properties directly within the lt style gt tag of our Single File Component SFC This feature is called v bind in CSS and this post is going to cover in detail how to use this new feature and what it actually means behind the scene I am a strong believer that an issue is best explained when the reader has full knowledge of the problem we are trying to solve If you are aware of the issue and just want to see how to pass variables in CSS in Vue you can jump to the next chapter named “v bind in CSS in practice if on the other hand this is new to you and want to really understand this concept I suggest you read on Introduction a real life exampleThere can be many situations in which you may want to create dynamic CSS properties In this section we are going to provide a few scenarios that may require the use of dynamic variables and therefore provide context to be used in our next sections Button with multiple stylesThis is probably the most common example that would require the use of variables in CSS In this scenario our requirements are Create a button component that allow an user to specify its look and feel with the use of properties The button woud accept a property of colour that will be used to define the component background colorThe above requirement is extremely typical in component based architecture Even if simple a fully developed component could require many properties to be configured The most common solution for this issue is the creation of a “rigid set of colours available and hardcode them directly using CSS classes like “button primary and “button secondary and then define the CSS for the specific style button primary background color red Dynamic Background imageA few years ago I was asked to create a component that would allow the creation of fancy cards This card could be highly configurable and one of the requirements was to allow properties that defined its background image Many developers may think that a solution to this problem would be to use a lt img gt tag Doing so would remove the need for a dynamic CSS variable but unfortunately this would not be semantically correct as a background image should be defined with CSS and if it is really just for decoration purposes There are very important accessible distinctions between a background image and an image element as mentioned in this article on WDocs Another possible solution for this requirement would be the use of JavaScript to dynamically change the value of the background image of a specific element Even if this resolution would solve our needs it would still create more code than we need and leave our components untidy Dynamic SizingIn the third and last example we are going to add some complexity to our requirements Nowadays flexbox and grid have made layout and dynamic sizing much easier than it was a few years ago There are still situations in which these two CSS features are not enough and some complex logic may still be required for us to achieve our needs A typical use case for the need for javascript and logic would be a page that needs to specify an element size depending on the number of items available on page or set the height of a component depending on the amount of text that the page contains I have had to develop both of these examples by hand and it was not a very clean solution as the framework would not allow me to do so V bind in CSS in practiceIt is now time to implement the above examples with the use of the new feature v bind in CSS The usage of the feature is very simple as it just requires you to use any property computed property or data variable directly within the style section of your single file component The variable need to be wrapped into a v bind method So for example if we want to define a button component that accepts a colour property using the options API we will write something like this lt template gt lt button class button gt Click me lt button gt lt template gt lt script gt export default props colour String lt script gt lt style gt button background color v bind colour lt style gt The above code shows the simplicity and the power of this new feature As you can see there is no need for any CSS preprocessor like LESS or SASS as this new feature takes full advantage of CSS variables which we will cover later in this post Using dynamic CSS variables is not only possible while writing components using the options API but it is also available with the newly introduced lt script setup gt The example below shows how the above code can be translated into the script setup lt template gt lt button class button gt Click me lt button gt lt template gt lt script setup gt const props defineProps colour String lt script gt lt style gt button background color v bind colour lt style gt The two examples shown above make use of simple properties In the example below we are going to make use of a nested variable available within our data object lt script gt export default data return styles backgroundColor red color blue lt script gt lt style gt button background color v bind styles backgroundColor color v bind styles color lt style gt The use of nested properties is very similar to the simple example provided previously in this post There are two main differences when using nested properties The variable name needs to be wrapped in quotesThe syntax used to access deep variables is the same one used in Javascript with the use of the “ to delimiter the object structure Reactive CSS variableIt can not be a Vue post unless we talk about reactivity The Vue Js framework is built on top of a powerful reactivity system that allows it to be fully reactive to any change that a user action or change may incur This reactivity can also be used to our advantage within our CSS lt template gt lt button class button click changeBackgroundColor gt Click me lt button gt lt template gt lt script gt export default data return backgroundColor red methods changeBackgroundColor this backgroundColor blue lt script gt lt style gt button background color v bind backgroundColor lt style gt In the code above our background colour will change from red to blue when the button is clicked How does v bind in CSS works behind the sceneThe last part of this article is going to go behind the scene and try to understand how this feature is working within the VueJs framework When I first learned about this feature I has the impression that it would be a build time feature and would just work on the first render hence not responsive Luckily for you all I was wrong As you have seen from the previous chapter this feature is fully responsive and works throughout the lifecycle of your component The way this feature works behind the scene is by defining CSS variables and assigning them to the root of the current component If we take the example above in which we define a backgroundColorproperty the code would look like this screenshot of v bind in CSS from the Vue SFC playgroundAs the above image shows the backgroundColor variable is actually being turned into a CSS variable named cff backgroundColor The extra character in the name ensures that there is no conflict in the variable name The beauty of this implementation is that it enhances the development experience as the variables are easily identifiable and easily changeable within the browser s development tool The following screenshot shows the how easy it is to grasp the variables Screenshot of the chrome developer tools that are showing the CSS variable being set from Vue JS ConclusionIf we look back at the real life example section that we used to start this post we can start to understand how clean and flexible our solutions could be Defining complex layout dimensions can easily be achieved using a simple computed property or developing a set of button styles can be executed using a simple data property containing all the possible iterations I have personally been waiting for this feature for a very long time as I have time and time again had to work around and write hacks to achieve very simple solutions Even if you may think that you have no current need to use the v bind in CSS feature I can guarantee you that you will surely have need of it soon after its discovery I hope you find your own use of this great feature and please feel free to post below a comment on real scenarios in which you used the above feature to help new readers	2022-06-09 14:29:54

海外TECH	DEV Community	Docker: Initialize custom users and databases in MongoDb	https://dev.to/mikelogaciuk/docker-initialize-custom-users-and-databases-in-mongodb-3dkb	Docker Initialize custom users and databases in MongoDb PurposeThere are situations when you need quick and re deployable database that doesn t need to be installed on your main OS or at external host in pre production state having all pre production databases users and tables or schema ready for development Since there is no real need to have full cluster working on Ks for this it s easier to deploy e g MongoDB with docker compose and remove it or reset into default state during development process TheoryImagine you have to work with an ETL that is going to fetch data from e g SQL Server and store it in MongoDB For this you would have database that you can spin whenever you want having always its default databases in initial state Of course you can create tables databases on fly during ETL startup but you can always create pre prod databases setup within the compose file First things firstFirst you need to create space folder cd home user reposmkdir mongodb devcd mongodb devAnd you need to have Docker and Docker Compose installed on your OS Docker composeIt is common practice to use docker compose for creating stacks that can be easily started or recreated depending on our needs First we need to createdocker compose yml file which is ours starting point cd home user repos mongodb devtouch docker compose yml Then we can start editing file within our IDE Code Editor e g Visual Studio Code code docker compose ymlOur simple MongoDb setup will use one service with two persistent volumes for data and logsThe first paragraph in docker compose yml is always about version of compose file that is going to be used by engine About versioning you can read more up here For this article I will use version The initial base of our compose file looks like this version services mongodb image mongo latest restart on failure environment MONGO INITDB ROOT USERNAME MONGO ROOT mongodb MONGO INITDB ROOT PASSWORD MONGO ROOT PASSWORD mongodb MONGO INITDB ROOT DATABASE MONGO ROOT DB mongodb networks services ports volumes mongodb data data db mongodb log var log mongodbvolumes mongodb data driver local mongodb log driver localnetworks services name MONGO NETWORK mongodb network Were we create service with a name mongodb that will use latest mongo image from DockerHub We set default user using built in variables that are mapped to our custom ENV s MONGO INITDB ROOT USERNAMEMONGO INITDB ROOT PASSWORDMONGO INITDB ROOT DATABASEIn the last part initialize network and setup ports forwarding and map data inside container into external storage volume to allow data persistence I think it s rather self explaining This trick with VARIABLE secret allows us to spin database without having proper ENV In other words if there is not env given in root directory or variables are empty docker compose will use default secrets stored in plain yaml It s good for development purposes but storing any default passwords in plan code is not allowed in production Initialize databases and users at stack startupIn order to add custom startup databases within its users we need to create sh file in our project directory touch mongo init shThen we map file to docker entrypoint by adding to volumes this line volumes mongo init sh docker entrypoint initdb d mongo init sh roThen we add our users passwords into environment section e g SALES PASSWORD SALES PASSWORD sales WAREHOUSE PASSWORD WAREHOUSE PASSWORD warehouse And place proper self exploratory code in sh file in order to create databases based on our variables set emongo lt lt EOFdb db getSiblingDB sales db createUser user sales pwd SALES PASSWORD roles role readWrite db sales db createCollection receipts db createCollection documents db createCollection invoices db db getSiblingDB warehouse db createUser user warehouse pwd WAREHOUSE PASSWORD roles role readWrite db warehouse db createCollection documents db createCollection stocks db createCollection invoices db createCollection orders EOF Final codeFinal docker compose yml file should look like this version services mongodb image mongo latest restart on failure environment MONGO INITDB ROOT USERNAME MONGO ROOT mongodb MONGO INITDB ROOT PASSWORD MONGO ROOT PASSWORD mongodb MONGO INITDB ROOT DATABASE MONGO ROOT DB mongodb SALES PASSWORD SALES PASSWORD sales WAREHOUSE PASSWORD WAREHOUSE PASSWORD warehouse networks services ports volumes mongo init sh docker entrypoint initdb d mongo init sh ro mongodb data data db mongodb log var log mongodbvolumes mongodb data driver local mongodb log driver localnetworks services name MONGO NETWORK mongodb network Running our sample databaseIn order to initialize it we type at our project root docker compose up dIn order to start or stop docker compose stopdocker compose startIn order to remove containers docker compose downIn order to remove containers together with volumes we type docker compose down v ResultIf everything is okay we should see something like this And be able to join our instance with users and passwords given in compose file	2022-06-09 14:26:26
海外TECH	DEV Community	Redux Without React	https://dev.to/vedanthb/redux-without-react-558e	Redux Without ReactIn this blog i will try to explain redux library without react Just Redux Why Because if we understand redux then we ll understand react redux redux bindings for react better So Redux is a relatively very small APIcomposecreateStorebindActionCreatorscombineReducersapplyMiddlewareYes just these five functions or methods We will understand each one by one Let s start with compose composeIts just a utility that come along with redux which is just a javaScript function that takes functions as arguments and returns a new function that executes them from right to left Yup thats it To understand that better lets say we have a have a bunch of functions that take a stringconst makeUppercase string gt string toUpperCase const logString string gt console log string const boldString string gt string bold We could call them all like this logString makeUppercase boldString redux But let s say if we wanted to pass this function as an argument to another function what would we do const boldenTheStringAndUppcaseItThenLogIt string gt logString makeUppercase boldString string This could take too long so we compose Which helps use make a new function that will execute all the function passed as arguments to compose args const boldenTheStringAndUppcaseItThenLogIt redux compose logString makeUppercase boldString boldenTheStringAndUppcaseItThenLogIt this will execute the functions from right to left boldString →makeUppercase →logString as “redux as argument sting and we re done with compose That is what compose is So far we have covered for the redux APINow let s understand createStore Create store creates a store A store is where we keep all our state But it doesn t just create a store however reducer is a function that we need to pass to the createStore we will cover what a reducer shortly let store redux createStore reducer console log store dispatch ƒdispatch subscribe ƒsubscribe getState ƒgetState replaceReducer ƒreplaceReducer four more functions dispatchsubscribegetStatereplaceReducer But what is a reducer after all A reducer is also just a function that takes in two arguments state state of the application action an action is event for example web socket messages action functions etc and it returns the new state so basically a reducer is a function where the first argument is the current state of application and the second is something that happened Somewhere inside the function we figure out what the new state of the world should to be based on whatever happened this is not how you should write a reducer just for exampleconst reducer state action gt state new state Let s try to understand this with an example Let s say we have a counter app and we want to increment the counter we will have an increment action now actions are also just functions and they need to have only have type const initialState value const reducer state initialState action gt if action type INCREMENT return value state value return state which can also be written asconst initialState value const INCREMENT INCREMENT const incrementCounterAction type INCREMENT only requires type others are optional payload meta error const reducer state initialState action gt if action type INCREMENT return value state value return state Alright there are a few things that we need to understand here You ll notice that we re creating a new object rather than mutating the existing one This is helpful because it allows us to figure out what the new state is depending on the current stateWe also want to make sure we return the existing state if an action we don t care about comes through the reducer You will also notice we made a constant called INCREMENT The main reason we do this is because we need to make sure that we don t accidentally mis spell the action typeーeither when we create the action or in the reducer Let s say we have a counter which has an increment button and add input which increment the counter and add to the counter whatever value we put in the input const initialState value state of the applicationconst INCREMENT INCREMENT constants const ADD ADD constants action creators fancy name for functions const increment gt type INCREMENT const add number gt type ADD payload number const reducer state initialState action gt if action type INCREMENT return value state value new state if action type ADD return value state value action payload new state return state default state So far we have understood compose and what createStore does and the four functions it creates what a reducer and action is But we need to still understand the four functions createStore creates So lets start with getState this function returns the current value of the state in the store dispatch how do we get actions into that reducer to modify the state Well we dispatch them const store createStore reducer console log store getState value store dispatch increment console log store getState value susbscribe This method takes a function that is invoked whenever the state in the store is updated const subscriber gt console log this is a subscriber store getState value const unsubscribe store subscribe subscriber store dispatch increment Subscriber store dispatch add Subscriber unsubscribe replaceReducer used for code splitting bindActionCreatorsEarlier in the blog we read about action which are functions So guess what bindActionCreators does binds actions functions together In the example below we have actions and reducersconst initialState value state of the applicationconst INCREMENT INCREMENT constants const ADD ADD constants action creators fancy name for functions const increment gt type INCREMENT const add number gt type ADD payload number const reducer state initialState action gt if action type INCREMENT return value state value new state if action type ADD return value state value action payload new state return state default state const store createStore reducer notice we have to do this like this everytime store dispatch increment Notice we have to dispatch the actions store dispatch increment every time this could be tedious in a large application we could do this in a cleaner way like thisconst dispatchIncrement gt store dispatch increment const dispatchAdd number gt store dispatch add number dispatchIncrement dispatchAdd or we could use compose remember compose for earlier in the blog const dispatchIncrement compose store dispatch increment const dispatchAdd compose store dispatch add We could also do this using bindActionCreators takes two arguments action creators action functions dispatchconst actions bindActionCreators increment add store dispatch actions increment Now we don t have to use bindActionCreators all the time but it s there With that we have completed of the redux API combineReducersGuess what this does Yes combines reducers When we have big applications we have many reducers For example when we have a blog application We would have reducers for storing the user information reducers for storing the blogs reducers for storing the comments In these big application we split the reducers into different files combineReducers is used when we have multiple reducers and want to combine them Say we have an application with users and tasks We can assign users and assign tasksconst initState users id name ved id name ananya tasks title some task assignedTo title another task assignedTo null reducer fileconst ADD USER ADD USER const ADD TASK ADD TASK const addTask title gt type ADD TASK payload title const addUser name gt type ADD USER payload name const reducer state initialState action gt if action type ADD USER return state users state users action payload if action type ADD TASK return state tasks state tasks action payload const store createStore reducer initialState store dispatch addTask Record the song store dispatch addUser moksh moksh is my brother s name console log store getState It would be nice if we could have two different reducers for the users and the tasksconst users state initialState users action gt if action type ADD USER return state action payload return state const tasks state initialState tasks action gt if action type ADD TASK return state action payload return state now we need to combine the reducers and we do that using combineReducersconst reducer redux combineReducers users tasks const store createStore reducer initialState Fun Fact All actions flow through all of the reducers So if you want to update two pieces of state with the same action you totally can applyMiddlewareTheres a lot of stuff that Redux can not do by itself so we can extend what Redux does using middleware and enhancers Now what are middleware and enhancers They re just functions that let us add more functionality to redux To be more accurate enhancers are functions that take a copy of createStore and a copy of the arguments passed to createStore  before passing them to createStore This allows us to make libraries and plugins that will add more capabilities how the store works We see enhancers in use when we use the Redux Developer Tools and when we want to dispatch asynchronous actions The Actual API for createStore createStore  takes one two or three arguments reducer required initialState  Optional enhancer  Optional Let s try to understand this with an example below is an enhancer that monitors the time it takes to update a state const

middleware next action Do stuff after the action has worked through the reducer next is either the next piece of middleware or it s store dispatch If you don t call next you will swallow the action

海外TECH	Engadget	The best camping and backpacking gear for dads	https://www.engadget.com/best-outdoor-gifts-for-dad-camping-backpacking-hiking-130037616.html?src=rss	The best camping and backpacking gear for dadsWe ve finally fully emerged from winter and dad might be feeling a little cooped up Now that the weather is getting warmer he s probably itching to get outside ASAP If your dad or father figure is the type to wander off into the woods ーperhaps for days at a time ーwe ve got some suggestions for Father s Day gifts Whether he s an ultra light backpacking maniac or a car camping comfort seeker we have just the thing JetBoil MiniMoJetBoil The Jetboil Flash is basically inescapable on the trail Its lightweight easily packable design and fast boil times make it attractive to backpackers But the MiniMo is worth the extra money and weight It s only one ounce heavier but the MiniMo s wider shorter cook cup is easier to handle Plus it can actually simmer things unlike the Flash And let me tell you dehydrated eggs are bad enough as is even without burning them in what amounts to a coffee tumbler mounted on a jet engine Trust me this is one of the best upgrades you can make to your dad s setup Buy Jetboil MiniMo at Amazon Leatherman Free series multitoolsLeatherman The Leatherman Free series has been a staple of Engadget buying guides ever since it debuted in There are plenty of options out there when it comes to multitools and many of them are great But the Free series was a serious game changer with its one handed access to every tool Plus everything including the knife locks into place so you re less likely to pinch or cut yourself It even requires less regular maintenance and cleaning than older Leatherman like the Juice series which while great tended to collect lint and dust in every nook and cranny at an alarming rate Your dad might not need every tool while hiking the Appalachian but he ll appreciate having options other than a knife or a rock Shop Leatherman Free series at AmazonBioLite HeadLamp BioLite After food water and shelter the next most essential thing on the trail is light The Biolite Headlamp is comfortable bright and long lasting It has both spot and flood modes plus a red light for saving your father s eyes at night And if you can get him the Extend Pack which is unfortunately often out of stock it also comes with a backup battery in case he needs to recharge on the trail along with a light diffusing stuffsack that basically turns his headlamp into a lantern he can hang from the ceiling of his tent or lean to Buy Headlamp at Amazon Sea to Summit X MugSea To Summit I love my old school enameled steel camp mug It s indestructible and has an undeniable classic look But it also conducts heat like nobody s business I ve burned my hands and lips on enough white hot cups of instant coffee to know they re just not that practical Sea to Summit s X Mug with cool grip promises to protect your little fingies from your boiling hot beverage Plus it collapses into a neat little puck for easy storage Admittedly I have not tried the Cool Grip model yet but I ve been using the company s collapsible bowl for over a decade And my hiking buddy uses the regular X Mug so I m pretty confident in recommending Sea to Summit s gear Buy X Mug at Sea to Summit Therm a rest NeoAir XLite img alt Therm a rest NeoAir XLite src Therm a rest I skipped a sleeping pad on my first backpacking trip I regretted it immediately Therm a Rest pads are the industry standard And the NeoAir XLite is pretty much smack in the middle of their backpacking lineup It s not the lightest or the warmest but it s probably the most versatile The R value a measurement of insulating power of is good enough for three season camping And it packs down to about the size of a water bottle This particular model has been around for a long time and it will probably continue to be a staple of Therm a Rest s lineup for years to come Buy NeoAir XLite mattress at Amazon starting at Garmin Enduro img alt Garmin Enduro src Garmin Full disclosure I haven t tested the Enduro Nor has anyone else at Engadget But we re big enough fans of Garmin s sports watches to feel comfortable recommending it But why pick this particular one Simple battery life Garmin says it lasts up to hours in GPS mode which is frankly absurd If your dad likes to quantify everything in his life including multi day hikes this is a pretty great way to do it It not only has a giant battery but also a built in solar charger Plus VO max estimates for trail runners heat and altitude acclimation tools for the parent that s into mountain climbing or desert hiking and even navigation features to keep him from getting lost And once he s found his way back to civilization he can snag a coffee at Starbucks using Garmin Pay Buy Enduro at Garmin Sawyer Squeeze water filterSawyer More than even food or shelter water is essential on the trail But dad can t just go drinking from streams and ponds nor can he carry enough with him for a multi day trip That s where the Sawyer Squeeze filter comes in handy There are tons of different ways to purify water from old school iodine tablets to boiling to pump filters But a squeeze filter system is often the fastest and easiest to use Sawyer s are probably the best known for good reason ーyou can fill up the pouch and drink straight from the filter or use the to fill up a reservoir or water bottle They re not ideal for places where dad might be reduced to getting water out of shallow muddy springs or where viral pathogens are a concern But they re perfect for more developed and regularly trafficked trails Buy Sawyer Squeeze filter at Amazon PackTowl UltralitePackTowl Your dad will need a towel on the trail Trust me Maybe he ll be lucky enough to find a shower Or perhaps he ll go for a dip in a lake Or maybe like me he just sweats enough to drown a small animal Regardless an Ultralite PackTowl is an absolute must have They re incredibly small and lightweight yet seem to have unlimited absorption power I m pretty sure they re actually a portal to another dimension where the water is stored I have two that I take with me on every trip one body sized and the other a face towel that stays clipped to my shoulder strap for when I need to mop my brow Buy PackTowel at Amazon starting at Snow Peak Titanium SporkSnow Peak This should go without saying but your dad needs a utensil to eat Yes even on the trail And there s nothing better than a good old fashioned spork to save space and weight I m a big fan of this titanium model from Snow Peak The company makes a ton of great gear but this simple and indestructible essential is probably my favorite Plus it comes in a handful of fun shades like blue green and purple in case your dad is known for his colorful personality Buy titanium spork at Amazon Aeropress GoAeropress If your dad would prefer to burn his lips on real coffee consider getting him an Aeropress for his adventures This is admittedly a luxury when you re backpacking But I ve tried instant coffee coffee “tea bags mesh coffee steeping contraptions camping french presses and honestly nothing makes better coffee with less cleanup than an Aeropress You could go for the full size model but the Go version shaves off a few precious ounces which could be crucial when trying to cut weight for a long trip But I actually bring the full size version when I hit the trail and have had no problems Buy Aeropress Go at Amazon Goal Zero Lighthouse Goal Zero Not every dad wants to strap three days worth of gear to his back and walk off into the woods Some are perfectly content driving up to a campsite pitching a tent and building a fire For them the Lighthouse is a great gift It is first and foremost an LED lantern perfect for food prep reading or even playing cards around camp But he can also use its mAh battery to charge his phone or headlamp And if he does happen to sap all its juice it has a hand crank for recharging through manual labor and an optional solar panel Buy Lighthouse at Amazon Joby GripTight Action Kit img alt Joby GripTight Action Kit src Joby Obviously part of the reason dad disappears into the wilderness is to escape from technology and enjoy nature But I m sure he wants to capture at least some of it for posterity Dragging a DSLR or even a mirrorless camera into the woods is overkill especially when he s probably got a pretty good camera with him already his cellphone Joby s unique GorillaPod tripods are perfect for the outdoors And the affordable Action Kit is pretty flexible It comes with a Bluetooth remote it can hold most phones or even a GoPro camera and it has a cold shoe adapter for a light or microphone Buy Joby Action Kit at Amazon Lodge Cast Iron Cook it AllLodge cast iron Look if he s driving up to the campsite anyway there s no need to fight with alarmingly thin steel pans or tiny fuel canister stoves The inch cast iron Cook it All from Lodge is the perfect campfire companion It can be a dutch oven a griddle or a skillet You can even bake a pizza inside it I ll admit though that I ve never considered baking a pizza while camping Cast iron is heavy and bulky but it s also damn near indestructible and holds on to heat for a long time which is good when you re dealing with a finicky campfire Plus if seasoned properly and treated with care cast iron is reasonably nonstick So dad might even be able to make some sunny side up eggs for breakfast Buy Lodge Cook It All at Amazon BackpacksEngadgetLast year we recommended Osprey s Atmos AG for anyone looking to be as comfortable as possible while backpacking This year we re doing the same just with some updated Osprey designs The Atmos has been given a minor face lift but the bigger deal is that it s now made with percent recycled materials You still get an integrated rain cover Anti Gravity suspension and fit on the fly adjustment system It s just now more eco friendly As part of the redesign the capacity has been increased to better reflect the pack s name Before if you bought the Atmos in a small you actually only got liters of storage Now the small is a full liters The one downside is that the new materials and carrying capacity have led to a slight increase in weight too with the S M Atmos AG coming in at four pounds ounces The women s equivalent of the Atmos is the Aura AG which is slightly smaller and lighter but has the same suspension system and similar lugging capacity And if you re on a tight budget this year you can still find the older model available in some places at a steep discount Buy Atmos AG at Osprey Buy Aura AG at Osprey TentsColemanObviously one of the most important pieces of camping equipment is a tent Not everyone s dad wants to spend their nights in a lean to But their needs will dictate what kind of tent to buy If your giftee is an avid backpacker who needs something ultra light to take on the trail I heartily recommend Big Agnes Tiger Wall UL It s not their lightest offering but it strikes a great balance between weight and convenience It can sleep two and has two vestibules for stowing gear but as a single person tent it s borderline luxurious Even with the optional footprint which I highly recommend for any tent the pack weight weighs under three pounds and the mtnGLO light system means no fussing with a lantern or headlamp to read and sort gear after dark If unabashed luxury is more your dad s thing consider REI s Wonderland At this is no casual investment but it should last quite some time The walls are nearly vertical and it reaches a height of six and a half feet in the middle meaning all but the tallest of humans should be able to stand upright inside The square feet of floor space is plenty of room for a family of six to sleep in and it has large ventilation windows to keep the inside cool during the hottest months The one caveat is that if you happen to do most of your camping in rainy environments you might want to shop around for something with fewer windows and better rainfly coverage Neither the Wonderland nor the Tiger Wall are cheap So if budget is an important factor or if dad is just looking to dabble in the world of car camping consider the Coleman Skydome Coleman gear is nothing fancy You can find it in practically any Walmart or Dick s Sporting Goods across the country But it s so ubiquitous because of its rock solid reliability and reasonable prices The Skydome is nearly the same size as the Wonderland but comes in at just or if you opt for the Darkroom model The ceiling is shorter and the walls more angled but if you re only using the tent to sleep in that shouldn t be a major concern Buy mtnGLO footprint at Big Agnes Buy Wonderland at REI Buy Coleman Skydome at Walmart	2022-06-09 14:30:18
