Redux is one of those libraries that makes perfect sense when you read the docs — but feels completely different when you're the one writing the slice, dispatching actions, and watching components react to state changes. Theory gets you started; building gets you fluent.
Ready to code? Try the challenge: Shopping cart with Redux
Let's be honest: for most React applications, Redux is overengineering. With Context and useReducer, you can build a global state solution that's just as capable — less boilerplate, fewer dependencies. But the job market has its own rules. Many teams still use Redux, many codebases were built with it, and many job descriptions list it as a requirement. Knowing Redux isn't about ideology — it's about being ready for the code you'll actually encounter.
This challenge puts you in the driver's seat of a real Redux workflow: you'll build a fully functional shopping cart powered by Redux Toolkit, from the slice logic all the way up to a multi-component React UI.
What you'll build
You'll create a complete shopping cart interface with the following features:
- Add products to the cart with quantity tracking
- Remove products individually
- Update product quantities in real time
- Toggle the cart's open/closed state from a global slice
- Display a running total derived from the cart state
