React Day Berlin

React Day Berlin 2022

This Talk explores the use of web workers in React to improve user experience and performance. It discusses the limitations of JavaScript rendering and how web workers can offload tasks to separate threads. The Talk also highlights the benefits of using concurrent mode in React and introduces the UseWebWorkerHook library for simplifying the creation of web workers. It emphasizes the considerations when using web workers and concludes with a mention of Postman's hiring and new feature release.

<p>We already know, ""if some task takes time, promisify it!"". But some tasks can be computation heavy and can take time to complete, so making them async is of no use since those have to be anyway get picked. Solution? Simple, multithreading! Yeah I know that React and in turn javascript is single-threaded but what if I told you that our life was a lie ever since? Enter web workers! Key takeaways of the talk: 1. An example of a simple product search showing why async js or concurrent mode cannot work. 2. Demystifying web workers. 3. How they make this magic happen under the hood? 4. The Question of life - Aren't they same as concurrent mode? 5. Comparing the same Product list app using web workers, diving deep into the performance. 6. How one can easily misuse web workers and how to avoid it.</p>
