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.

Let's have a go at some questions to test our knowledge on what we have just learned:

  1. In the GitHub GraphQL Explorer, create a query to return the last five open issues in the React project. Return the issue title and the URL in the response.
  2. Enhance the last query and make the number of issues that are returned a parameter and make this default to five.
  3. Create a mutation in the GitHub GraphQL Explorer to unstar a starred repository. The mutation should take a required repository id in as a parameter.
  4. What part of the HTTP request does the GraphQL query go in?
  5. What part of the HTTP request does the GraphQL mutation go in?
  6. How can we make the response from the react-apollo Query component type safe?
  7. Is caching on or off by default when you scaffold a project with react-boost?
  8. What prop can we use on the Mutation component to update the local cache?
