Learn React Hooks

Overview of this book

React Hooks revolutionize how you manage state and effects in your web applications. They enable you to build simple and concise React.js applications, along with helping you avoid using wrapper components in your applications, making it easy to refactor code. This React book starts by introducing you to React Hooks. You will then get to grips with building a complex UI in React while keeping the code simple and extensible. Next, you will quickly move on to building your first applications with React Hooks. In the next few chapters, the book delves into various Hooks, including the State and Effect Hooks. After covering State Hooks and understanding how to use them, you will focus on the capabilities of Effect Hooks for adding advanced functionality to React apps. You will later explore the Suspense and Context APIs and how they can be used with Hooks. Toward the concluding chapters, you will learn how to integrate Redux and MobX with React Hooks. Finally, the book will help you develop the skill of migrating your existing React class components, and Redux and MobX web applications to Hooks. By the end of this book, you will be well-versed in building your own custom Hooks and effectively refactoring your React applications.

Interactions between Hooks

Our whole blog app now works in the same way as before, but it uses our custom Hooks! Until now, we have always had Hooks that encapsulated the whole logic, with only constant values being passed as arguments to our custom Hooks. However, we can also pass values of other Hooks into custom Hooks!

Since Hooks are simply JavaScript functions, all Hooks can accept any value as arguments and work with them: constant values, component props, or even values from other Hooks.

We are now going to create local Hooks, which means that they will be placed in the same file as the component, because they are not needed anywhere else. However, they will still make our code easier to read and maintain. These local Hooks will accept values from other Hooks as arguments.

The following local Hooks will be created:

  • A local Register Effect Hook
  • A local Login Effect Hook...
