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.

Data flow

In the last two chapters, we saw how to create single reusable components and how to compose them together effectively.

Now, it is time learn how to build a proper data flow for sharing data across multiple components in our application.

React enforces a very interesting pattern to make data go from the root to the leaves. This pattern is usually called Unidirectional Data Flow, and we will see it in detail in this section.

As the name suggests, in React data flows in a single direction from the top to the bottom of the tree. This approach has many benefits because it simplifies the components' behavior and the relationship between components, making the code more predictable and maintainable.

Every component receives data from its parent in the form of props, and props cannot be modified. When the data is received, it can be transformed into new information and passed to the other children down the tree. Each of the children can hold a local state and use it as a prop for its nested...
