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.

Interacting with GraphQL APIs

GraphQL is an open source web API language for reading and writing data that is maintained by Facebook. It allows the client to specify exactly what data is returned and request multiple data areas in a single request. This efficiency and flexibility makes it a compelling alternative to a REST API. GraphQL also supports both reading and writing data.

In this chapter, we'll start by experimenting with some GraphQL queries against GitHub to get familiar with the syntax by using the GitHub GraphQL API explorer. We'll explore how we both read and write GraphQL data and how to specify exactly the way we want the data in the response returned to us.
