海外TECH	DEV Community	Frontend vs Backend: What's The Difference?	https://dev.to/nimapinfotech/frontend-vs-backend-whats-the-difference-30gj	Frontend vs Backend What x s The Difference The world of coding has introduced some fascination for software developer engineers I always get asked the questions about the front and aspects of the software Some also ask about the backend aspects of the software What are these terms Can they be used interchangeably What is the significance of software development using these terms Anyone new to the world of software engineering can easily get confused with search terms Terms that full stack development front end development and Backend development are synonyms for each other And there are more and less related to certain aspects of software development Today in this article we will demystify these terms and answer what it means all about software development using these termsTo begin with website development is all about the creation and development of different websites and web applications Compared to user interface designing and User experience designing the overall website development focuses on ensuring that your website functions well User interface designing and experience designing are concerned with the usability of the website application Front end development and backend development are the two different aspects concerned with website development or web application development What is FrontEnd Development Front end development always ensures that the user s perspective is kept and preserved as far as website development is concerned Front end development is a branch of Computer programming that mainly focuses on the creation and coding of different elements and features that are concerned with the visual aspect of the software Front end development is all about making sure the elements that come in visual contact are in perfect order with each other These elements and concerned with the visual upset of the website being functional enough for the user Another term to describe the front end is the client side end of the application The job of a front end developer is to bring to life the visual aspects of the Software of the website under development As a developer you will be more focused to see what is happening on the screen you will also ensure that the website is functioning and provide interactiveness to the user Front end developers state the visual designs from user interface and User experience developers and do the job of bringing the website or web application to life These are one of the many ways to ensure that the website functions as well as the needs and requirements of the user Think of this example as visiting a shopping mall or a grocery shop The products and items are arranged in a fashion that is easy to find for the users Customers and Consumers can easily shop for the items that they want and do the required sale and purchase the items Items and products on neatly arranged in a stack that is easy to visualize and find At the top of the item stack you will find the price list that denotes the purchase price of the item Products and services are neatly arranged in a fashion that is visually appealing to the user Likewise similarly in front end development the elements such as forms boxes checkboxes and buttons images are neatly arranged in a fashion that is visually appealing and satisfying for the user Front end development is mainly concerned with providing a great experience to the users through the mediums of developing the visual aspects of the application as defined You can Hire FrontEnd Developer if you are looking for Frontend Web Development Front end technologies mainly include JavaScript and other Technologies which dictates and authorizes the creation of the visual aspect of the application What is Backend Development In plain and simple terms the backend development focuses on the administrative part of the application that visual users can t see This is what defines the different interactiveness that happens on a website as developers we can define this on the server side of the website aspects like dashboard and metrics that control the visual aspect of the application are defined by the backend development Say for example you are running a social media application or website You would need a place to store the data and all your user s information The facility that enables this is called the database and developer good news database Technologies like Oracle or SQL Server The database connects both the front end and the backend aspects of the application together It provides a medium for developers and engineers to store all the data in the most effective and efficient way possible Even though the users of the website can t see the back end of the application the back and aspect of the application are only visible to administrators and website owners Content is put on the backend which is visible on the front end through a series of alterations and updates happening on the backend The backend aspect DB storing and functioning of the data as well as the different facilities and features provided by the website and showing that it functions well You can Hire Backend Developer if you are looking for Backend Development FrontEnd VS BackEnd What s the difference Are you still thinking I have confused about the front end and the backend aspects of the application The front end deals with the visual part of the web application which the users are able to see customers coming to your website or application cant see what is happening on the website Whereas does backend aspects control the overall functionality and feature set of the application that enables website administrator to have fine control over the different functions of the application There are databases that control and store data that is processed by the backend and presented by the front end So in plain and clear terms three different aspects to a software application the website front end the database to store the data and the website backend All the three functions are in harmony together to provide the feature set and bring the website to life All of these elements and components allow customers to do different things on a website Things like purchase submission of user data chatting and gaming are some of the features that modern websites have To control these functions it is essential to have a harmonious balance between the three entities of the website the frontend the backend and the database Conclusion So this is the main difference between Frontend vs Backend We hope you have now understood what the backend stands for and what the frontend does in website

海外TECH	DEV Community	Comprehensive Guide to GraphQL Clients, part 1	https://dev.to/drago/comprehensive-guide-to-graphql-clients-part-1-2372	Comprehensive Guide to GraphQL Clients part IntroductionAs you already know GraphQL is a query language for APIs It is a declarative language which means that it is easy to write queries However it is also a flexible language which means that it is easy to write queries that are not declarative This guide will help you to write declarative queries Until now you have created a server that returns data However you have not used the data in any way This guide will help you to use the data in a declarative way GraphQL clients are used to sending queries to a GraphQL server Requests are sent in the form of a query string The response is returned in the form of a JSON object The response is a JSON object that contains the data that is requested A request is made to a GraphQL server using the HTTP protocol so you can use the same client as a client for RESTful APIs Getting Started GraphQL IDE sIDEs are test tools to check the correctness of your queries You can define your queries in the IDE and then send them to the server The server will return the data that is requested if the query is correct There are a lot of IDEs available The most popular and the simplest IDE for GraphQL queries is GraphiQL The modern clone of GraphiQL is GraphQL Playground The environment is cleaner and has some advanced features The recent IDE for GraphQL queries is Apollo Explorer All around tools such as Postman and Insomnia are great tools for testing either GraphQL queries or RESTful APIs CurlThe tool for quickly sending queries to a GraphQL server is curl It is a command line tool that allows you to send simple queries to a GraphQL server curl X POST H Content Type application json d query countries name It is useful for debugging and quick testing Install ReactJSThe first step is to install ReactJS as our library of choice for creating UI components If you have not installed ReactJS you can install it using the following command in the command line npx create react app my appcd my appnpm startNow you are ready to deep dive into the GraphQL world Native FetchFetch is a native built in JavaScript client for making HTTP requests Let s see how to use fetch to send a query to a GraphQL server Create a file FetchData js in the root of your project import useState useEffect from react const FetchedData gt const country setCountry useState const fetchData async req res gt try const response await fetch method POST headers Content Type application json body JSON stringify query countries name const data await response json const countriesName data countries map c gt countriesName push c name setCountry countriesName catch error console log error useEffect gt fetchData const countriesList country map c index gt lt ul key index gt c lt ul gt return lt gt lt h gt Countries lt h gt countriesList lt gt export default FetchedData Then in App js you can use the component FetchedData import FetchedData from FetchData export default function App return lt FetchedData gt AxiosAxios is a JavaScript library for making HTTP requests It is a wrapper around the XMLHttpRequest object It s a promise based HTTP client for the browser and node js Axios automatically parses JSON responses It is a shorthand for fetch Install Axios using the following command in the command line npm install axiosFetchData jsimport useState useEffect from react import axios from axios const FetchedData gt const country setCountry useState const fetchData async req res gt try const response await axios post query countries name const data response data const countriesName data countries map c gt countriesName push c name setCountry countriesName catch error console log error useEffect gt fetchData const countriesList country map c index gt lt ul key index gt c lt ul gt return lt gt lt h gt Countries lt h gt countriesList lt gt export default FetchedData App js is the same as before graphql requestFor simple requests graphql request is a good choice This library is only kb and it is one of the fastest and lightest GraphQL clients It supports async await typescript isomorphism and works on both the client and server sides Install graphql request npm install graphql request graphqlThen you need to import the library and create a client If you are not familiar with the code in these examples I recommend you to read the documentation about the fundamentals of React FetchData jsimport useState useEffect useCallback from react import request gql from graphql request const FetchedData gt const country setCountry useState const countriesQuery gql query countries name const url const fetchData useCallback async gt try const response await request url countriesQuery const countries response const countryName countries map c i gt lt ul key i gt c name lt ul gt setCountry countryName catch error console log error countriesQuery useEffect gt fetchData fetchData return lt gt lt h gt Countries lt h gt country lt gt export default FetchedData App js is the same as in the previous example graphql hooksGraphql hooks is a library that allows you to use GraphQL clients in React It is a promise based library for the browser and node js Conceptually it is similar to graphql request but the difference is that first is formed a client and then the whole app is wrapped in a context in which the client is available wrapping app Tiny bundle only kB gzipped Install graphql hooks npm install graphql hooksApp jsimport FetchedData from FetchData import GraphQLClient ClientContext from graphql hooks const client new GraphQLClient url export default function App return lt ClientContext Provider value client gt lt FetchedData gt lt ClientContext Provider gt FetchData jsimport useState useEffect useCallback from react import useQuery from graphql hooks const FetchedData gt const country setCountry useState const countriesQuery query countries name const loading error data useQuery countriesQuery const fetchData useCallback async gt try const countries data console log countries const countryName countries map c i gt lt ul key i gt c name lt ul gt setCountry countryName catch error console log error data useEffect gt fetchData fetchData if loading return lt p gt Loading lt p gt if error return lt p gt Error error message lt p gt return lt gt lt h gt Countries lt h gt country lt gt export default FetchedData If you don t need advanced features graphql hooks is an ideal choice because it is very functional and easy to use It is also very lightweight Even has a self contained development environment in form of extension	2022-04-09 10:16:19
