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 Apollo GraphQL client

Apollo client is a client library for interacting with GraphQL servers. It has many benefits over using a generic HTTP library like axios, such as being able to read and write data declaratively with React components right in our JSX and having caching switched on right out of the box.

In this section, we'll refactor what we built in the last section with axios to use Apollo, and then extend our app a little more to include a GitHub repository search.

Installing Apollo client

Our first job is to install Apollo into our project.

  1. To add Apollo client to our project, let's install the following packages via npm:
npm install apollo-boost react-apollo graphql
  • apollo-boost contains everything...
