Learn React with TypeScript 3

By: Carl Rippon

Overview of this book

React today is one of the most preferred choices for frontend development. Using React with TypeScript enhances development experience and offers a powerful combination to develop high performing web apps. In this book, you’ll learn how to create well structured and reusable react components that are easy to read and maintain by leveraging modern web development techniques. We will start with learning core TypeScript programming concepts before moving on to building reusable React components. You'll learn how to ensure all your components are type-safe by leveraging TypeScript's capabilities, including the latest on Project references, Tuples in rest parameters, and much more. You'll then be introduced to core features of React such as React Router, managing state with Redux and applying logic in lifecycle methods. Further on, you'll discover the latest features of React such as hooks and suspense which will enable you to create powerful function-based components. You'll get to grips with GraphQL web API using Apollo client to make your app more interactive. Finally, you'll learn how to write robust unit tests for React components using Jest. By the end of the book, you'll be well versed with all you need to develop fully featured web apps with React and TypeScript.

Using the rest and spread syntax is very common nowadays, particularly when building React apps. We've seen how TypeScript 3, with the enhancement of tuples, allows us to use rest and spread in a strongly-typed fashion.

We've also seen how we can use the unknown type to reduce our use of the any type. The unknown type does require us to write more code, but it also allows us to create a more strongly-typed, more maintainable code base.

TypeScript has always made working with large code bases easier. With the introduction of project references, we can now split our solution into smaller projects more easily. This approach makes large solutions even more maintainable and flexible, and also yields faster build times with the new --build flag.

We briefly went through how using defaultprops in a React component has improved. We'll be using this frequently as...
