Overview of this book

Filled with useful React patterns that you can use in your projects straight away, this book will help you save time and build better web applications with ease. React 17 Design Patterns and Best Practices is a hands-on guide for those who want to take their coding skills to a new level. You’ll spend most of your time working your way through the principles of writing maintainable and clean code, but you’ll also gain a deeper insight into the inner workings of React. As you progress through the chapters, you’ll learn how to build components that are reusable across the application, how to structure applications, and create forms that actually work. Then you’ll build on your knowledge by exploring how to style React components and optimize them to make applications faster and more responsive. Once you’ve mastered the rest, you’ll learn how to write tests effectively and how to contribute to React and its ecosystem. By the end of this book, you'll be able to avoid the process of trial and error and developmental headaches. Instead, you’ll be able to use your new skills to efficiently build and deploy real-world React web applications you can be proud of.

Taking Your First Steps with React

Hello, readers!

This book assumes that you already know what React is and what problems it can solve for you. You may have written a small/medium application with React, and you want to improve your skills and answer all of your open questions. You should know that React is maintained by the developers at Facebook and hundreds of contributors within the JavaScript community. React is one of the most popular libraries for creating UIs, and it is well known to be fast, thanks to its smart way of working with the Document Object Model (DOM). It comes with JSX, a new syntax for writing markup in JavaScript, which requires you to change your thinking regarding the separation of concerns. It has many cool features, such as server-side rendering, which gives you the power to write universal applications.

In this first chapter, we will go through some basic concepts that are essential to master in order to use React effectively, but are straightforward enough for beginners to figure out:

  • The difference between imperative and declarative programming
  • React components and their instances, and how React uses elements to control the UI flow
  • How React changed the way we build web applications, enforcing a different new concept of separation of concerns, and the reasons behind its unpopular design choice
  • Why people feel JavaScript fatigue, and what you can do to avoid the most common errors developers make when approaching the React ecosystem
  • How TypeScript changed the game
