海外TECH	DEV Community	React Hooks	https://dev.to/shardulpathak/react-hooks-4c0o	React HooksReact HooksHooks are the new feature introduced in the React version It allows you to use state and other React features without writing a class Hooks are the functions which hook into React state and lifecycle features from function components It does not work inside classes Hooks are backward compatible which means it does not contain any breaking changes Also it does not replace your knowledge of React concepts Motivation Behind HooksHooks solves wide range of problems Hooks also helps to minimize the complexity of components One of the most common features any application provides is the states State is a plain JavaScript object used by React to represent an information about the component s current situation It s managed in the component just like any variable declared in a function Before Hooks when we wanted to maintain states we need to implement class components with state Maintaining class components with states is always cumbersome process as it requires to write more code need to remember syntax etc There is one sentence used in React Documentation Classes confuse both people and machinesWe can find when we use class components with states the logic is very much tightly coupled with classes and it is very difficult to reuse the class components it also not easy to organize the code when we use classes Classes along with states and other class members requires “this So the understanding of this keyword is very important in case of classes Actually this keyword is confusing in JavaScript we have to understand how this works in JavaScript which is very different from how it works in most languages There is one disadvantage we have to remember to bind the event handlers No Breaking ChangesBefore we continue more on Hooks please note that Hooks are Completely opt in We can write hooks in few components without rewriting existing code backwards compatible Hooks don t contain any breaking changes Why we should opt in React HooksBefore Hooks Functional components only having props It renders the values from props Let s consider below scenario where we need to print name of the user Functional component without using Hooksexport function PrintName props return lt div gt lt h gt Name props name lt h gt lt div gt Class Component with Lifecycle method componentDidMountimport React from react class PrintName extends React Component state names async componentDidMount try const res await fetch api data this setState names await res json catch e console error e render return lt h gt Hello this state names lt h gt Let s refactor the PrintName component from class to functional component using useEffect Hookimport React useEffect useState from react function PrintName const names setNames useState useEffect gt fetch api data then res gt setNames res data return lt gt lt div gt Hello names lt div gt lt gt From above example we can see when we use functional components without hooks they are not able to do much they just print the values received in props When we used the class component we can see they are more flexible and we can bring dynamic nature by implementing life cycle methods e g componentDidMount But we also observed it requires more code to accommodate the dynamic nature into class components Also as per our discussion in above section we need to write cumbersome code to maintain state in class components The changes we made to bring state management and dynamic nature we introduced complexity also these changes made class component more rigid we cannot reuse or separate the logic Finally when we refactor the same example with Hook useEffect in functional component we can easily achieved same output with very minimal code changes without any new complexity When to use a HooksIf you write a functional component and then you want to add some state to it previously you do this by converting it into a class But now you can do it by using a Hook inside the existing function component Rules of HooksHooks are similar to JavaScript functions but you need to follow these two rules when using them Hooks rule ensures that all the state full logic in a component is visible in its source code These rules are Only call Hooks at the top levelDo not call Hooks inside loops conditions or nested functions Hooks should always be used at the top level of the React functions This rule ensures that Hooks are called in the same order each time a component render Only call Hooks from React functionsYou cannot call Hooks from regular JavaScript functions Instead you can call Hooks from React function components Hooks can also be called from custom Hooks Pre requisites for React HooksNode version or aboveNPM version or aboveHooks StateHook state is the new way of declaring a state in React app Hook uses useState functional component for setting and retrieving state Hooks EffectThe Effect Hook allows us to perform side effects an action in the function components It does not use components lifecycle methods which are available in class components In other words Effects Hooks are equivalent to componentDidMount componentDidUpdate and componentWillUnmount lifecycle methods Side effects have common features which the most web applications need to perform such as Updating the DOM Fetching and consuming data from a server API Setting up a subscription etc In React component there are two types of side effects Effects Without CleanupEffects With CleanupCustom HooksA custom Hook is a JavaScript function The name of custom Hook starts with use which can call other Hooks A custom Hook is just like a regular function and the word use in the beginning tells that this function follows the rules of Hooks Building custom Hooks allows you to extract component logic into reusable functions Built in HooksHere we describe the APIs for the built in Hooks in React The built in Hooks can be divided into two parts which are given below Basic HooksuseStateuseEffectuseContextAdditional
