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.

Chapter 3. Create Truly Reusable Components

To create truly reusable components we have to understand the different possibilities that React gives us for defining components and when it is better to choose one or another. A new type of component has been introduced in React which lets us declare a component as a stateless function. It is crucial to understand this component and learn when and why it should be used.

You may have already utilized the internal state of components, but you may still be unclear about when it should be used and the problems it can give us. The best way to learn is by seeing examples, and we will do that by starting from a component which serves a single purpose and transforming it into a reusable one.

Let's first take a step back and revisit the basic concepts, so that we can move forward and create a living style guide of components by the end of this chapter.

In this chapter we will see:

  • The different ways we can follow to create React components and when we should...
