海外TECH	DEV Community	How to Deploy a Multi-Container React.js and Node.js Application With Docker Compose	https://dev.to/bravinsimiyu/how-to-deploy-a-multi-container-reactjs-and-nodejs-application-with-docker-compose-334h	How to Deploy a Multi Container React js and Node js Application With Docker ComposeDocker Compose is a powerful Docker tool for developing and running multi container Dockerized applications Docker is an open source platform for developing and running applications in an isolated environment known as a container A container is a standalone executable package that contains the libraries source code and dependencies needed to run an application With Docker Compose you create a docker compose yml file to run all the containers in your project as a single application The file will contain all the container configurations such as volumes container names and port mappings It also specifies the Dockerfiles for building the Docker images In this tutorial we will create a backend Express server using Node js We will then create a front end application using React js and connect it to the backend server We will then use Docker Compose to deploy the two applications We will also access them on the web browser Let s start working on our applications PrerequisitesThis tutorial assumes you are familiar with the following React jsNode jsDockerTo implement this tutorial you will need the following already installed on your computer VS Code code editor Node js framework Docker Desktop Creating the Backend Express Server using Node jsTo create the Express server using Node js follow the steps illustrated below Step Create a working directory named docker compose app and open it with VS Code In the working directory create a new directory folder named node and cd into the node directory This directory will contain the libraries source code and dependencies needed to create the application Step Initialize the application using the following code npm init yThe command will initialize the application and generate the package json file The next step is to install all the dependencies for the application as follows npm i g nodemonnpm i expressAfter running the command in your terminal it will install express and nodemon We will use the installed express package to create the server We will use nodemon to watch and monitor the backend files Nodemon will detect changes in the backend files and automatically restart the server It will prevent us from restarting the backend server manually after making changes to the application Step Next open the package json file and the following npm script for nodemon to start working dev nodemon L app js Step In the node directory create a new file named server js This file will have the logic for creating our backend server Step Copy and paste the following code snippet in the server js file const express require express const cors require cors const app express app use cors app get req res gt res json id title Album Review When we all Fall asleep where do we go id title Book Review How can we escape this labyrinth of suffering id title Documentary Review How can we escape the rat race app listen gt console log connected on port The code snippet above will create a get route The frontend application will get the review titles from this route Running the Backend Express ServerTo run the Backend Express Server application run the following npm command in your terminal npm run devThe npm command will start and run our server on http localhost as shown in the image below The image shows the backend is running and displaying the reviews Let s start working on our frontend React js application Creating the frontend React js applicationTo create the frontend React js application follow the steps illustrated below Step In the docker compose app working directory run the following npx command to create a boilerplate for a React js applicationnpx create react app reactThe npx command above will create a new directory named react in the docker compose app working directory Now cd into the react directory Step Navigate inside the react directory and open the src directory Step While in the src directory open the App js file and add the following code snippet import useEffect useState from react import App css function App const reviews setReviews useState useEffect gt fetch http localhost then res gt res json then data gt setReviews data return lt div className App gt lt header className App header gt lt h gt all Reviews lt h gt reviews amp amp reviews map blog gt lt div key blog id gt blog title lt div gt lt header gt lt div gt export default App The added code snippet will create a frontend react application It will fetch the review titles from this backend get route Our backend application is running on http localhost The next step is to run the frontend React js application as follows Running the frontend React js applicationTo run the frontend React js application execute the following command in your terminal npm startThe npm command will start and run the frontend React js application on http localhost as shown in the image below The image shows the frontend React js application running and fetching the review titles from the backend Let s create the Dockerfiles for the two applications Docker Compose will use the Dockerfiles to build and run the containers Create the Dockerfile for the Backend Express ServerThe Dockerfile will contain all the commands for building the Docker image for the backend server application While in the node directory folder create a new file named Dockerfile In the created Dockerfile add the following commands to create a Docker image It uses node alpine as the base image for the Node js applicationFROM node alpine It installs the nodemon package globally for monitoring and watching the backend Express serverRUN npm install g nodemon Creating the working directory named app WORKDIR app Copying all the tools and dependencies in the package json file to the working directory app COPY package json Installing all the tools and dependencies in the containerRUN npm install Copying all the application source code and files to the working directory app COPY Exposing the container to run on this port EXPOSE Command to start the Docker container for the backed server applicationCMD npm run dev The next step is to create a Dockerfile for the frontend React js application Create the Dockerfile for the frontend React js applicationIn the react directory folder create a new file named Dockerfile In the created Dockerfile add the following commands to create a Docker image It uses node alpine as the base image for the frontend React js applicationFROM node alpine Creating the working directory named app WORKDIR app Copying all the tools and dependencies in the package json file to the working directory app COPY package json Installing all the tools and dependencies in the containerRUN npm install Copying all the application source code and files to the working directory app COPY Exposing the container to run on this port EXPOSE Command to start the Docker container for the frontend React js applicationCMD npm start Now that we have both Dockerfiles the next step is to create a docker compose yml file which contains all the containers configurations Create a docker compose yml fileThis file will enable us to run and deploy the two containers using Docker Compose We will add the containers as a service The docker compose yml file will have two services Using the created file we will spin up the two containers It will run them as a single application To create the two Docker Compose services follow the steps below Step In the docker compose app working directory create a new file docker compose yml file Step Next add the first service named node using the following code snippet Version of Docker composeversion services Add the node js service node Location to the node js dockerfile build context node Name of the dockerfile dockerfile Dockerfile container name node container ports Host port Container port volumes Bind mounts configuration node app Ignoring any changes made in the node modules folder app node modulesThe code above will create a service named node It also shows the location of the Node js Dockerfile It shows the container name as node container and port mapping The node container will run on port We also add volume for this service This volume will map the local project folder to the working directory in the container Any changes made in the local project folder will be updated automatically in the container It saves time rebuilding the whole container from scratch when change the files in the local project folder Step Next let s add the service named react for the React js application container After the node service add the following code snippet react Location to the react js dockerfile build context react Name of the dockerfile dockerfile Dockerfile container name react container ports Host port Container port stdin open trueThe code above will create a service named react It also shows the location of the React js Dockerfile It shows the container name as react container and port mapping The react container will run on port If you follow the steps above correctly the final docker compose yml will be as shown below Version of Docker composeversion services Add the node js service node Location to the node js dockerfile build context node Name of the dockerfile dockerfile Dockerfile container name node container ports Host port Container port volumes Bind mounts configuration node app Ignoring any changes made in node modules folder app node modules react Location to the react js dockerfile build context react Name of the dockerfile dockerfile Dockerfile container name react container ports Host port Container port stdin open trueNow that we have added all our services to the file the next step is to build and run the two containers Running the two Containers using Docker ComposeTo build and run the two Containers using Docker Compose execute the following command in your terminal docker compose up buildThe command will run the two containers and display the following output in your terminal The output shows both the node container and react container are running We can access the node container on http localhost and react container on http localhost The images below show the deployed containers running in the web browser node containerreact container ConclusionIn this tutorial you have learned how to deploy a multi container React js and Node js Application using Docker Compose We created a backend Express server using Node js We then created a front end application using React js After completing these steps we created Dockerfiles for these two applications We also created a docker compose yml file We used the docker compose yml to build and run the two application containers We successfully deployed the Docker containers using Docker Compose We accessed them on the web browser You can download the complete source code for this tutorial here Happy Deployment	2023-07-19 08:46:55
海外TECH	DEV Community	Exploring the Power of TypeScript Generics: Constraints, Utility Types, Literal Types, and Recursive Structures	https://dev.to/rajrathod/exploring-the-power-of-typescript-generics-constraints-utility-types-literal-types-and-recursive-structures-78g	Exploring the Power of TypeScript Generics Constraints Utility Types Literal Types and Recursive Structures TypeScript GenericsGenerics in TypeScript allow you to create reusable components or functions that can work with different types They provide a way to parameterize types enabling the creation of flexible and type safe code Here s an explanation of generics with an example Generic Functions You can define a generic function by specifying a type parameter inside angle brackets lt gt This type parameter can then be used as a placeholder for a specific type when the function is called Here s an example function identity lt T gt arg T T return arg let result identity lt string gt Hello console log result Output Hello let numberResult identity lt number gt console log numberResult Output In the identity function above the type parameter T represents a generic type When the function is called the provided argument s type will be inferred or you can explicitly specify the type within the angle brackets Generic Interfaces You can also use generics with interfaces to create reusable interfaces that work with various types Here s an example interface Container lt T gt value T let container Container lt number gt value console log container value Output let container Container lt string gt value Hello console log container value Output Hello In the Container interface the type parameter T is used to define the value property When implementing the interface you can specify the actual type for T Generic Classes Generics can also be applied to classes allowing you to create classes that operate on different types Here s an example class Queue lt T gt private items T enqueue item T this items push item dequeue T undefined return this items shift const numberQueue new Queue lt number gt numberQueue enqueue numberQueue enqueue console log numberQueue dequeue Output const stringQueue new Queue lt string gt stringQueue enqueue Hello stringQueue enqueue World console log stringQueue dequeue Output Hello In the Queue class above the type parameter T represents the type of items stored in the queue Different instances of the class can be created with specific types Generics provide flexibility and type safety by allowing you to write reusable components that can work with various types They enhance code reuse maintainability and enable the creation of more generic and flexible APIs in TypeScript Generic ConstraintsGeneric constraints in TypeScript allow you to restrict the types that can be used with a generic type parameter By specifying constraints you can ensure that the generic type parameter meets certain criteria such as having specific properties or implementing certain interfaces This helps to provide more specific type information and enables the usage of properties or methods specific to the constrained types Here s an explanation of generic constraints with an example interface Animal name string age number function getOldest lt T extends Animal gt animals T T let oldest T null null for const animal of animals if oldest null animal age gt oldest age oldest animal if oldest throw new Error No animals found return oldest const animals Animal name Dog age name Cat age name Rabbit age const oldestAnimal getOldest animals console log oldestAnimal name Output Cat console log oldestAnimal age Output In the example above we have a generic function getOldest that finds the oldest animal from an array of animals The generic type parameter T is constrained to Animal which means that T must be a subtype of Animal and have the name and age properties defined Within the function we iterate through the animals and compare their ages tofind the oldest one The type of oldest is T null allowing us to handle the case when no animals are found By applying the extends keyword with the Animal interface T extends Animal we ensure that only types that satisfy the Animal interface can be used with the function This provides type safety and allows us to access the name and age properties on the returned object without any type errors By using generic constraints you can create more specific and reusable functions that operate on a restricted set of types It allows you to leverage the properties and methods specific to the constrained types ensuring type safety and enhancing code clarity Utility TypesTypeScript s utility types are a powerful toolset of predefined generic types that simplify type manipulation and transformation They offer convenient operations and transformations on types providing developers with enhanced capabilities to work with complex type systems This article dives into some commonly used utility types in TypeScript and illustrates their usage with practical examples Partial lt T gt Description Creates a new type with all properties of T set to optional Example interface User name string age number type PartialUser Partial lt User gt const partialUser PartialUser name John Required lt T gt Description Creates a new type with all properties of T set to required Example interface User name string age number type RequiredUser Required lt User gt const requiredUser RequiredUser name John age Readonly lt T gt Description Creates a new type with all properties of T set to read only Example interface User name string age number type ReadonlyUser Readonly lt User gt const readonlyUser ReadonlyUser name John age Error Cannot assign to name because it is a read only property readonlyUser name Jane Record lt K T gt Description Creates a new type with properties of type T for each key K Example type Weekday Monday Tuesday Wednesday Thursday Friday type DailySchedule Record lt Weekday string gt const schedule DailySchedule Monday Meeting Lunch Tuesday Gym Wednesday Thursday Conference Friday Coding Pick lt T K gt Description Creates a new type by picking properties K from T Example interface User name string age number email string address string type UserProfile Pick lt User name email gt const userProfile UserProfile name John email john example com Omit lt T K gt Description Creates a new type by omitting specific properties K from the original type T Example interface User name string age number email string address string type UserWithoutEmail Omit lt User email gt const user UserWithoutEmail name John age address Main St Exclude lt T U gt Description Creates a new type by excluding types from T that are assignable to U Example type MyObject id number name string age number isActive boolean type ExcludedKeys Exclude lt keyof MyObject name isActive gt ExcludedKeys will be id age Extract lt T U gt Description Creates a new type by extracting types from T that are assignable to U Example type MyObject id number name string age number isActive boolean type ExtractedKeys Extract lt keyof MyObject name age gt ExtractedKeys will be name age Advanced TypesLiteral types allow you to specify exact values as types Literal types can be used to enforce specific values on variables function parameters and properties providing additional type safety and expressiveness Here s an overview of literal types and some examples String Literal TypesDescription Represents a specific string value Example let status active inactive status active Valid status pending Error Type pending is not assignable to type active inactive Numeric Literal TypesDescription Represents a specific numeric value Example let age age Valid age Error Type is not assignable to type Boolean Literal TypesDescription Represents a specific boolean value Example let isCompleted true false isCompleted true Valid isCompleted false Valid isCompleted Error Type is not assignable to type true false Enum Literal TypesDescription Represents a specific value from an enumeration Example enum Direction Up UP Down DOWN Left LEFT Right RIGHT let direction Direction Up Direction Down direction Direction Up Valid direction Direction Left Error Type Direction Left is not assignable to type Direction Up Direction Down Literal types provide more precise type information and help catch potential errors at compile time They are particularly useful when you want to restrict the possible values of a variable or when working with union types that have specific literal values By leveraging literal types you can enhance the type system and ensure the correctness of your code Recursive typesRecursive types also known as self referential types are types that refer to themselves in their own definition They allow you to create data structures or types that contain references to the same type within their own structure Recursive types are useful when working with nested or hierarchical data structures Here are a few examples of recursive types Linked List interface ListNode lt T gt value T next ListNode lt T gt const node ListNode lt number gt value const node ListNode lt number gt value const node ListNode lt number gt value node next node node next node Binary Tree interface TreeNode lt T gt value T left TreeNode lt T gt right TreeNode lt T gt const nodeA TreeNode lt string gt value A const nodeB TreeNode lt string gt value B const nodeC TreeNode lt string gt value C nodeA left nodeB nodeA right nodeC Nested Objects interface Person name string children Person const personA Person name Alice const personB Person name Bob const personC Person name Charlie personA children personB personC Recursive types allow you to create flexible and hierarchical data structures by referencing the same type within their definition They enable you to work with nested data and handle complex relationships between entities When using recursive types it s important to ensure that the recursion has a terminating condition or a base case to avoid infinite nesting It s worth noting that TypeScript supports recursive types through the concept of type references However the compiler imposes some limitations on directly self referencing types such as strict circular references If you encounter such limitations you can leverage utility types like Partial Record or conditional types to define recursive structures indirectly Thank You Thank you for taking the time to read my blog

interest and look forward to sharing more valuable content in the future Thank you once again	2023-07-19 08:35:34
海外TECH	DEV Community	Randomly Generated Avatars	https://dev.to/dagnelies/randomly-generated-avatars-18n5	Randomly Generated AvatarsAs a follow up from an earlier article regarding the update to randomly generated default avatars for Passwordless ID I wanted to post a how to This is a beginner tutorial since making such avatars is actually really simple TL DR Here is the full demo The image formatThe first thing you should think about is the image format usually one of Jpeg great for real user photos due to the high compression ratio However this compression also produces some blur on lines and sharp edges As such it is not ideal for the avatars we are going to make PNG theses have lossless compression In other words every pixel remains exactly the same as it was originally drawn Edges and lines remain sharp SVG these are scalable vector graphics Unlike a raster of pixels it is a declarative format describing shapes and paths Of course you could also save it as a quality Jpeg to avoid any quality loss but then it is larger than PNGs Jpeg compression is amazing though for common photos In our case we picked SVG for the upcoming avatar pictures In the past SVG was kind of avoided because support was not always well supported for all software platforms This is however largely in the past SVG offers several benefits the first is being scalable Due to its vector nature it is perfectly sharp at any scale even if you zoom in on a K display Other raster formats like Jpeg or PNG become pixelated when zooming in The other is being more compact While the byte size of Jpeg PNG grows with picture size SVG grows proportional to the shape s complexity For relatively simple stuff like the avatars here they are super compact The SVG template SVG is an XML format that describes the shapes As such what will be generated is a big XML string To be more exact we will fill the template below with the appropriate values lt svg xmlns width height gt lt defs gt lt linearGradient id gradient x startX y startY x endX y endY gt lt stop offset stop color hsl startHue gt lt stop offset stop color hsl endHue gt lt linearGradient gt lt defs gt lt rect x y width height fill url gradient gt lt text x y text anchor middle dominant baseline middle font size font family Times New Roman fill ffffff gt char lt text gt lt svg gt Once this template is filled with meaningful values you will obtain an avatar SVG image that can be stored as a plain normal svg file Alternatively you also deliver it as data URL since it is quite compact This simply means encoding the resource directly instead of a plain URL fetching it It is composed of two parts the mime type image svg xml in this case and the base encoded data This can be used like any other URL in the src tag of an image as follows lt img src data image svg xml base the base encoded svg Voilà you got your image Getting some random valuesThe missing step is now filling this SVG template with some random values Alternatively if you want something more deterministic you could also use the hash value of the name for example As you saw in the SVG template instead of using RGB colors HSL colors were used This stands for Hue Saturation Lightness This makes it easy to generate bright colors from all rainbow colors with maximal color saturation and average lightness Gradient colors const startHue Math round Math random const endHue Math round Math random Gradient direction const angle Math random Math PI Calculate the start and end points of the gradient const startX Math cos angle const startY Math sin angle const endX startX const endY startY The character to appear on the avatar const char name charAt toUpperCase For the gradient direction it s a bit more tricky since an angle cannot be provided directly There are some transforms available but to ensure the widest compatibility with SVG renderers sticking to the basics seems a safe bet As such the angle is converted to starting and ending coordinates for the gradient Thank youThe resulting full source code can be seen in the example provided at the beginning A Pen by Arnaud Dagnelies codepen io	2023-07-19 08:10:24
