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.

React Router gives us a comprehensive set of components for managing the navigation between pages in our app. We learned that the top-level component is Router, which looks for Route components beneath it where we define what components should be rendered for certain paths.

The Link component allows us to link to different pages with an app. We learned that the NavLink component is like Link, but it includes the ability to style it depending on whether it is the active path or not. So, NavLink is perfect for the main navigation element in an app and Link is great for other links that appear on pages.

RouteComponentProps is a type that gives us access to route parameters and query parameters. We discovered that React Router doesn't parse query parameters for us, but can use the native JavaScript URLSearchParams interface to do this for us.
