![]() When you use Hooks in your codebase, you may achieve faster iterations, faster learning curves, higher quality development, improved user experiences, smaller error margins, and much more.īuild Your Own “Redux” State Management Using HooksĪs soon as Hooks launched, many development teams planned to migrate all their codebase from Redux, a popular state management tool frequently used with React, to Hooks. Higher quality development processes : Taken all together, these benefits have a very positive impact on the overall development process.This benefit also applies for existing team members. More maintainable code: Function components are easier to read and easier to digest, especially for new developers joining an existing team with an existing code base.This is because a pure function accepts N parameters and returns the same output given the same combination of inputs (this holds true as long as you implement your components as pure functions). More testable code : By definition, function components are easier to test.You get smaller bundles and, as a result, faster loading applications. Smaller and more performant applications : Function components transpile into smaller pieces of code than class components.(It’s very common to see a lot of different things for different purposes in functions like componentDidMount and componentDidUpdate.) This means you can avoid having non-related logic in traditional lifecycle events. Improved code structure: You can restructure complex components more easily by splitting them into smaller pieces.You can read more about this and see examples of custom hooks in the official React documentation. When you do, you can reuse that logic and test both parts separately. Reusable code: You can isolate stateful management logic from the visual aspect of your components more easily.Working with Hooks, you get all the benefits of class components together with the ease of functional components: Instead, if a developer needed state management or lifecycle methods, they had to use class components, which are significantly more complex. ![]() However, prior to the release of Hooks, functional components did not have state or lifecycle methods. They also have better performance benefits. Functional components are easier to read, debug, and test than class components. We’ll also implement our own “Redux” state management layer using Hooks, so you can see what you will need to do to migrate.Ī functional component in React is a JavaScript function that accepts props and returns a React element. In this blog post, we’ll explore the benefits of using Hooks in your ReactJS application. With Hooks, you get such powerful functionality, you might decide to migrate your codebase. Hooks lets you write React applications using only functional components. Introduced in React version 16.8 (February 2019), React Hooks adds support for state management and lifecycle events to functional components.
