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.

Project references

TypeScript 3 allows TypeScript projects to depend on other TypeScript projects by allowing tsconfig.json to reference other tsconfig.json files.

This makes it easier to split our code up into smaller projects. Our frontend code might be in TypeScript, in addition to having our backend in TypeScript. With TypeScript 3, we can have a frontend TypeScript project, a backend TypeScript project, and a shared TypeScript project that contains code that is used in both the frontend and backend. Splitting our code up into smaller projects can also can give us faster builds, because they can work incrementally.
