海外TECH	DEV Community	An introduction to React Hooks	https://dev.to/ashikarose/an-introduction-to-react-hooks-3f58	An introduction to React HooksIntroductionHooks are here to aid you if you don t like lessons Hooks are methods that let you leverage React s state and lifecycle capabilities without having to use classes It allows you to connect into React state and lifecycle features from function components as the name implies Hooks don t work inside classes and are backwards compatible which means they don t introduce any new features So it s entirely up to you whether you want to use them or not This new functionality allows you to leverage all of React s features including function components Make sure your hooks are written in standard follow format To ensure that hooks are called in the same sequence every time call them at the top level of React functions Avoid calling them from inside loops nested functions or conditions Also make sure you re calling them from a React function component rather than a JavaScript function If you don t follow that guideline you can end up with some unusual behaviours To ensure that these rules are applied automatically React includes a linter plugin To use hooks you don t need to install anything They re included with React starting with version To set up the React development environment you ll need the newest version of Node js to run npx follow these steps npx create react app exploring hooksReact hooks have rendered render props and HOCs Higher Order Components practically unnecessary making sharing stateful code much more pleasant React comes with a number of hooks pre installed The most important are useState and useEffect Need for React HooksTo reuse stateful logices The render props pattern and higher order components HOC are two advanced React ideas It is not possible to reuse stateful component logic in React in any way Although the use of HOC and render properties patterns can solve this problem it makes the code base inefficient and harder to understand because components are wrapped in a slew of others to share functionality Hooks allow us to exchange stateful functionality in a much better and cleaner way without altering the component hierarchy This keyword The keyword this is used for two reasons The first has nothing to do with React and everything to do with javascript To work with classes we must first understand how the javascript this keyword works which is rather different from other languages Although the principles of props state and unidirectional data flow are simple to grasp using the this keyword when implementing class components might be challenging Event handlers must also be bound to the class components Classes have been discovered to not concise efficiently leading in unreliable hot reloading which can be remedied with Hooks Simplifying challenging scenarios When designing components for complicated scenarios like data fetching and event subscription all relevant code is likely to be scattered throughout multiple life cycle methods Effect HookWe use the Effect hook i e useEffect from React function components to conduct side effects tasks like modifying the DOM data fetching and so on These actions are so named because they can have an impact on other components and aren t possible to perform during rendering componentDidMount componentDidUpdate and componentWillUnmount are all powered by the UseEffect hook Because the components require access to their state and props UseEffect is declared inside them UseEffect can be called at the beginning of a render at the end of each render or to specify clean up depending on how we express them They run by default after every render including the first one import React useState useEffect from react function usingEffect const count setCount useState default behaviour is similar to componentDidMount and componentDidUpdate useEffect gt Change document title document title Clicked count times return Clicked count count setCount count gt Button The document title is updated every time the count is updated in the example above Because it runs at the first render and after every update useEffect works similarly to componentDidMount and componentDidUpdate combined This is useEffect s default behaviour although it can be altered Let s have a look at how If you want to use useEffect as componentDidMount then you can pass an empty array in the second argument to useEffect as in the below example import React useState useEffect from react function usingEffect const count setCount useState Similar to componentDidMount useEffect gt Only update when component mount document title You clicked count times return Your click count is count setCount count gt Button Hooks StateThe useState function component is used to define alter and use states using hooks The current state and a function to update the state are returned as two value pairs It s something along these lines This is not the same as setState in a class The fact that setState does not merge the old and new states distinguishes it UseState is a function component that can be called from within a function component or from an event handler The initial state is supplied as an input to useState and it is used on the first render There are no restrictions on the number of state hooks that can be used in a single component we can use as many as we wish import React useState from react function usingStateHook use useState to declare state variable count const count setCount useState return display count value Your click count is count on click update count value using setCount setCount count gt Button In the above example we ve included a counter that keeps track of how many times the button has been pressed In this case useState sets the count to and returns the setCount function which can be used to update the count In the onClick event handler we call setCount with the value count Here count is the previous count value for example if the count was two before setCount will increase it by one to three Custom HooksReact also allows us to create our own hook which is a javaScript function with the word use at the beginning of its name and can call other hooks When we have parts that can be reused in our project we normally develop custom hooks We must first define them which may include the use of other hooks before we can refer to them as other hooks function FriendStatus props const isOnline useFriendStatus props friend id if isOnline null return Loading return isOnline Online Offline function FriendListItem props const isOnline useFriendStatus props friend id return props friend name Wrapping UpHooks allow us to leverage different functionalities such as lifeCycle functions without having to develop classes Get assistance from the best react development agency Hooks come in a variety of shapes and sizes each with its own set of functions The useState and useEffect hooks are the most popular among them	2021-12-13 07:13:56
