TypeScript is an amazing technology that helps developers write better code with less errors - simply because it let's you catch & fix type-related errors whilst writing the code (instead of when testing the application).

But using TypeScript with React can sometimes be tricky. Especially when building more complex, dynamic components, defining the right types can be challenging.

That's why I built this course!

Because this course will teach you how to use TypeScript with React - and, of course, the course will introduce you to all the core concepts & patterns you need to work with components, state, side effects & more in a type-safe way!

This course will:

  • Teach you WHY using TypeScript in your React projects might be a good idea
  • Introduce you to the key TypeScript concepts you'll need - when working with React & in general
  • Get you started with using TypeScript with React - for components, state & more
  • Explore more advanced, complex patterns & examples
  • Help you with building dynamic or even polymorphic components in a type-safe way
  • Teach you how to use TypeScript with React's Context API
  • Explore how you can enhance code used with useReducer() with help of TypeScript
  • Cover data fetching & useEffect() with TypeScript
  • Use the popular Redux library in a type-safe way
  • Build or improve multiple demo projects so that can apply your knowledge

By the end of the course, you'll be able to use TypeScript in your own (future) React projects and write better, more type-safe code.
