Keep the Main Thread Free With Web Workers

When heavy compute runs on the main thread, the UI stutters. I'll show how to spot main-thread blocking, then move filtering/aggregation work into Web Workers with a clean message protocol, debouncing, progress updates, and cancellation so the UI stays smooth.

Happy to be joining #CASCADIAJS for the 3rd time! 🎉

Every year I come away learning something new from the talks and workshops, and it’s always great to reconnect with old friends while meeting new people like Akshay Upadhya B in the community. Looking forward to another amazing event full of learning, inspiration, and great conversations!🙂

Wrote a good old-fashioned post-conference reflections post about CascadiaJS. You should read it!

Thanks to Carter Rabasa and Carrie Rabasa for staying in the game, and to everyone who made it happen on/off/behind the scene. 🙇 I hope to be back next year!
