I've made my React book available as a GitHub repo so teacher or student can easily download as a zip, clone it, or fork it if you'd like to help improve it.
The book covers various aspects of React such as
- Fundamentals, how create components, working with data and functions, rendering data
- Redux, the pattern itself and all the things that goes with it like the store, actions, reducers and saga
- Advanced APIs and patterns like Context API, Render props, Hooks and more
- Testing, using Jest, Nock and React Testing library
