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.

Trade-offs of Redux

To wrap up, let us summarize the pros and cons of using Redux in a web application. First, let us start with the positives:

  • Provides a certain project structure that allows us to easily extend and modify code later on
  • Fewer possibilities for errors in our code
  • Better performance than using React Context for state
  • Makes the App component much simpler (offloads state management and action creators to Redux)

Redux is a perfect fit for larger projects that deal with complex state changes, and state that is used across many components.

However, there are also downsides to using Redux:

  • Writing boilerplate code required
  • Project structure becomes more complicated
  • Redux requires a wrapper component (Provider) to connect the app to the store

As a result, Redux should not be used for simple projects. In these cases, a Reducer Hook might be enough. With a Reducer Hook...
