海外TECH	DEV Community	How To React.js?	https://dev.to/sujeshgathe/how-to-reactjs-4kl6	How To React js In this article we would put our heads together about all the things you need to understand to master React js And why react is the future of front end development React developers are in great demand since it is used by Yandex Netflix Facebook and many more well known businesses We would be discussing about all the fundaments of react js and what technologies and tools are available in react for implementing it into our front end design React BasicsFront end is the part of the web that is displayed to the user responsible for sending data and making requests to the back end side also called the server side Here are some basics you should know about react to begin with your web app development ComponentsYou may split the user interface using React components so that each component can be reused and handled separately Or to put it another way any application you create with React will be built up of what are known as components Using components makes creating user interfaces considerably simpler You may view a user interface UI divided into several separate parts or components and work on them individually before merging them all into a parent component to create your final UI A React component can be either “stateful or “stateless “Stateful components are of the class type while “stateless components are of the function type Example of Stateless Componentimport React from react an example of function type componentconst ExampleComponent props gt return lt h gt Welcome to Educative lt h gt export default class App extends React Component render rendering ExampleComponent component in App Component return lt div gt lt ExampleComponent gt lt div gt The stateless component named ExampleComponent is added into the component in the example above The only element in the ExampleComponent is the h Example for Stateful Componentimport React from react an example of class type componentclass ExampleComponent extends React Component constructor props super props this state heading This is an Example Component render return lt div gt lt h gt this props welcomeMsg lt h gt lt h gt this state heading lt h gt lt div gt export default class App extends React Component render const welcomeMsg Welcome to Educative return lt div gt lt ExampleComponent welcomeMsg welcomeMsg gt lt div gt The stateful component named ExampleComponent is added into the component in the example above PropsReact components receive parameters called Props HTML attributes are used to pass props to components React s data flow between components is uni directional from parent to child only Props are an optional input and can be used to send data to the component They are read only since they are immutable attributes They are useful for displaying fixed values as a result of this StatesState a unique built in object in React enables components to produce and manage their own data Contrary to props components cannot generate or maintain state internally although they can pass data with state State should not be modified directly but it can be modified with a special method called setState Examplethis state id “ wrongthis setState correct id JSXJSX is Referred as JavaScript XML We can write HTML in React thanks to JSX React s use of JSX makes adding and writing HTML simpler It is a JavaScript syntactic enhancement It should be used with React to specify how the user interface should appear Although JSX may resemble a template language it has all of JavaScript s capabilities EventsReact has the ability to take action in response to user events much as HTML DOM events The same HTML eventsーclick change mouseover etc ーare available in React Event handlers determine what action is to be taken whenever an event is fired This could be a button click or a change in a text input Essentially event handlers are what make it possible for users to interact with your React app Handling events with React elements is similar to handling events on DOM elements with a few minor exceptions Conditional RenderingReact allows us to build many components that each have the required behavior Then based on a few factors or the status of our application we may render them In other words a component chooses which components it will return depending on one or more circumstances The same way that JavaScript s conditions function in React conditional rendering does as well The elements that reflect the current state are created using JavaScript operators and React Component updates the UI to match them Example of conditional rendering Consider the following component that only renders a warning button if a warning message is passed as props function Warning props const warningMessage props if warningMessage return null return lt gt lt button gt Warning lt button gt lt gt Now if you pass in warning Message to the component a warning button will be rendered However if you don t will return null and the button will not be displayed lt Warning warning Message Warning message gt the warning button is rendered lt Warning gt the warning button is not rendered React UI frameworksMaterial UIMaterial UI is the best and most preferred library among the front end developers To develop a user interface in our React apps we can simply import and use several components from the Material UI package As a result the developers may save a lot of time by not having to create everything from start It s using an MIT License so it s free even for commercial use It uses the same license as React See Material UI provides us Various in built Templets components icons APIs etc to enhance our web app thus makes it easy for a developer its just like buying or borrowing any component for our project rather than building it from scratch for more info checkAnt DesignThe Experience Technology Department of Ant Financial has developed Ant Design a design language for middleware that aims to standardize user interface requirements for middleware projects cut down on unnecessary implementation and design costs and free up resources for design and front end development It is the second most popular UI for React developers It is a Enterprise class UI with a set of high quality react components specially designed for web applicationsYou could require data flow solutions like Redux or MobX while developing actual projects Chakra UIYou may create React apps using the Chakra UI component toolkit which is straightforward flexible and user friendly Chakra UI helps us build innovative features for our web app To implement most trending feature we use Chakra UI Light and Dark UI Chakra is extremely time efficient has excellent accessibility defaults is well designed and documented and looks fantastic right out of the box If you need more information about Chakra UI Discord channel for Chakra React BootstrapTo construct responsive component based UI components ReactJS Bootstrap was designed as a front end toolkit component library As a substitute for JavaScript Bootstrap it provides easily accessible dynamic and easy to integrate components to speed up our development process JQuery is used by Javascript Bootstrap to power the interface of its components Because Javascript Bootstrap directly manipulates the Document Object Model DOM it is in opposition to ReactJS declarative methodology There have been instances when ReactJS projects have used Javascript Bootstrap but their support components have only used basic Vanilla Bootstrap stylesheets and have not used JQuery Hence React developers developed their component library that follows the Virtual DOM concept and does not involve JQuery Important HooksIn React hooks are a brand new feature They provide state and other React capabilities without the need for class creation useStateWe can keep track of the state in a function component with the React useState Hook By executing useState in our function component we initialize our state UseState returns two values after accepting an initial state The current StateFunction that updates the current stateExampleimport useState from react function FavoriteColor const color setColor useState useEffectYou may instruct React that your component needs to do an action after rendering by using this Hook React will keep track of the function you gave which we ll refer to as our effect and run it once the DOM adjustments have been made UseRefBetween renderings you may maintain values using the useRef Hook It may be used to hold a changeable value that when altered doesn t require a new rendering It may be applied to directly access a DOM element UseContextUtilizing the context is primarily intended to provide your components access to certain global data and to re render when that global data is modified When you have to pass along props from parents to kids context solves the props drilling problem UseReducerTwo parameters are accepted by the useReducer Hook Your own state logic is included in the reducer function and initialState can either be a simple value or more often than not an object The dispatch method and the current state are returned by the useReducer Hook Redux should be used in applications that have several features With these features sharing chunks of the same information While using the useContext and useReducer the Redux functionalities can be reproduced UseCallbackThe useCallback hook is utilized when a component s child is rendering it repeatedly without a reason Pass an array of dependencies together with an inline callback In the event that one of the dependencies has changed useCallback will only return a memoized version of the callback State Management ToolsDevelopers may check the application s state using state management to make sure that modifications reflect the business processes and real world context in the right way The tools used for State management in react are ReduxRedux is a design pattern and framework that uses actions or events to manage and update application state With rules guaranteeing that the state may only be altered in a predictable manner it acts as a central repository for state that must be utilized across the whole program It is one of the most commonly used tool by full stack developers Redux can be used for any application that places a high priority on the ability to predictably store states It should be clear that Redux can be used for the client side frontend with user interfaces MobxA straightforward scalable and state management solution without boilerplate is MobX The code is decoupled portable and most importantly simple to test because it is possible to maintain application state independently of any UI framework It uses the publish subscribe design paradigm to implement observable data Redux outperforms MobX in terms of popularity scalability and the development community However MobX could be your best option if you want to get up to speed quickly and create straightforward apps with minimal boilerplate code HookstateThe declarative React useState concept is extended with new functionality by the Hookstate package and is wrapped in a global version Its main characteristics include A plugin system to enhance the library s functionality with state validation and persistency State management in TypeScript is supported by Hookstate by default React JS PackagesThis files are a kind of manifest file for your application This file plays a very important role in the react application development and deployment In short we can say Package json Metadata associated with project All Dependencies with version scripts Some of the most useful package that you should be familiar with are React RouterReact router is a common library for routing in React It permits switching between views of different React Application components permits changing the browser URL and keeps the UI in sync with the URL React router can be an overkill for certain projects where all you need is basic navigation and routing functionalities In that context React Router is not necessary at all Learn how react hooks can replace react routers AxiosOne of the most commonly used package now a days to built efficient and user friendly application It is a popular library mainly used to send asynchronous HTTP requests to REST endpoints Axios is a Javascript library that implements the Promise API that is native to JS ES and is used to make HTTP requests using node js or XMLHttpRequests from the browser It allows client side XSRF protection and may be used to intercept HTTP requests and answers Additionally it can cancel requests React QueryReact Query is frequently referred to as React s missing data fetching library However it simplifies the process of retrieving caching syncing and updating server data in your React apps in a more technical sense Facebook uses React Query for small parts of its main page There are some apps built fully with React As React Query s fetching mechanisms are agnostically built on Promises you can use React Query with literally any asynchronous data fetching client including GraphQL StorybookA development environment for UI components is called Storybook You may use it to explore a library of components see each component s many states and design and test components in real time By separating components it accelerates and simplifies development This enables you to focus on one element at once Without having to launch a complicated development stack force specific data into your database or use your application s navigation you may create full user interfaces This are the most fundamental tools and technologies used now a days for front end development Thus to be a successful front end developer using react js you must be familiar using this technologies I hope this article was able to provide proper guidance to endure react js expertise	2022-09-29 00:01:21
