Overview of this book

Reading, navigating, and debugging a large frontend codebase is a major issue faced by frontend developers. This book is designed to help web developers like you learn about ReactJS and TypeScript, both of which power large-scale apps for many organizations. This second edition of Learn React with TypeScript is updated, enhanced, and improved to cover new features of React 18 including hooks, state management libraries, and features of TypeScript 4. The book will enable you to create well-structured and reusable React components that are easy to read and maintain, leveraging modern design patterns. You’ll be able to ensure that all your components are type-safe, making the most of TypeScript features, including some advanced types. You’ll also learn how to manage complex states using Redux and how to interact with a GraphQL web API. Finally, you’ll discover how to write robust unit tests for React components using Jest. By the end of the book, you’ll be well-equipped to use both React and TypeScript.

Using Apollo Client

In this section, we will learn about Apollo Client and use it within the app we have built, replacing the use of React Query and fetch.

Understanding Apollo Client

Apollo Client is a client library for interacting with GraphQL servers. It has query and mutation hooks called useQuery and useMutation, like React Query. Apollo Client also stores the data in a client cache like React Query and requires a provider component placed above the components requiring GraphQL data.

One thing that Apollo Client does that React Query doesn’t is that it interacts with the GraphQL API directly instead of requiring a function to do this.

Installing Apollo Client

Our first job is to install Apollo Client, which we can do by running the following command in a terminal:

npm i @apollo/client graphql

This library includes TypeScript types, so no additional package is required to be installed.
