React 16.8: Official Hook Support

Introducing React Hooks: A New Way of Building React Applications

React.js, one of the most popular JavaScript libraries, has released version 16.8.0, which includes official support for Hooks. With over 100 releases, more than 130,000 GitHub stars, and 2 million-plus projects, React continues to make life easier for developers building amazing user interfaces.

What are Hooks?

Hooks are functions that let you “hook into” React state and lifecycle features from function components. They allow you to use state and other React features without writing a class, making it easier to reuse logic and simplify your code.

Motivation behind Hooks

The React team identified several problems that developers face when building applications with React. These include:

• Difficulty of reusing stateful logic: There was no clear way to attach reusable behavior to a React component.
• Complex components become hard to understand: Logic can be passed from one method to another, making it difficult to maintain and debug.
• Classes are sometimes confusing: Classes can be unintuitive, especially for new developers.

How Hooks Solve these Problems

Hooks provide a platform to let you use React features without classes. They allow you to:

• Extract stateful logic: You can extract stateful logic from a component so it can be tested independently and reused.
• Split complex components: You can split one component into smaller functions based on what pieces are related to what.
• Use React features without classes: You can use React features, such as state and lifecycle methods, without writing a class.

Getting Started with React v16.8

To get started with React Hooks, you need to install the new version 16.8 with your favorite registry. You can do this by running:

• npm install [email protected] or
• yarn add [email protected]

Using Hooks in Your Application

Once you have installed React 16.8, you can start using Hooks in your application. Here is an example of a simple Hook:
“`jsx
import { useState } from ‘react’;

function Counter() {
const [count, setCount] = useState(0);

return (

);
}
“`
Testing Hooks

The React team added a new API called ReactTestUtils.act() in this release. It ensures that the behavior in your tests matches what happens in the browser more closely.

Conclusion

React Hooks provide a new way of building React applications. They allow you to use state and other React features without writing a class, making it easier to reuse logic and simplify your code. With the release of React 16.8, you can start using Hooks in your application today.
