React applications can suffer performance issues when handling long tasks on the main thread. Using Web Workers, scripts can run in background threads, preventing the UI from becoming unresponsive. This guide covers the basics of Web Workers, their types, and their integration into a React app to offload intensive tasks. It includes examples of creating a Dedicated Worker, communication methods between the main thread and worker, and implementing these concepts in a React project to filter and display products efficiently.

How to Use Web Workers in React

Great read. Would love some more info on Service workers. The getProducts logic would make more sense in a lib folder, instead of inside the data-worker.js file, but guessing that’s for example reasons.
Great job.

Thanks a lot. It was really easy to follow. The only thing I missed was some real world use cases.
