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.

Installing Redux

Before we can use Redux, we need to install it along with the TypeScript types. We will also install an additional library called redux-thunk, which we need in order to implement asynchronous actions:

  1. If we haven't already, let's open our React shop project in Visual Studio Code from where we left off in the last chapter. So, let's install the core Redux library via npm in the terminal:
npm install redux

Note that the core Redux library contains TypeScript types within it. So, there is no need for an additional install for these.

  1. Let's now install the React-specific bits for Redux. These bits allow us to connect our React components to the Redux store. Let's install these via npm:
npm install react-redux
  1. Let's also install the TypeScript types for react-redux:
npm install --save-dev @types/react-redux
  1. Let's install redux...
