React Design Patterns and Best Practices

By: Michele Bertoli

Overview of this book

Taking a complete journey through the most valuable design patterns in React, this book demonstrates how to apply design patterns and best practices in real-life situations, whether that’s for new or already existing projects. It will help you to make your applications more flexible, perform better, and easier to maintain – giving your workflow a huge boost when it comes to speed without reducing quality. We’ll begin by understanding the internals of React before gradually moving on to writing clean and maintainable code. We’ll build components that are reusable across the application, structure applications, and create forms that actually work. Then we’ll style React components and optimize them to make applications faster and more responsive. Finally, we’ll write tests effectively and you’ll learn how to contribute to React and its ecosystem. By the end of the book, you’ll be saved from a lot of trial and error and developmental headaches, and you will be on the road to becoming a React expert.

The state

We have seen how to create a component with the factory, extending the React class or using stateless functional components.

Let's now go deeper into the topic of state and see exactly why it is important to use it and find out how it works.

We will learn when we should use stateless functions rather than stateful components and why that represents a fundamental decision in designing components.

External libraries

First of all, it is important to understand why we should consider using the state inside our components and why it can help us in different ways.

Most of the tutorials or boilerplates for React, already include external libraries to manage the state of the application, such as Redux or MobX.

This leads to a common misconception for which you cannot write a stateful application using React only, which is far from the truth.

The direct consequence is that many developers try to learn React and Redux together, so they never find out how to use the React state correctly.
