Web Workers promise to help us find that balance and let us build fast and responsive applications even when doing heavy work, but the APIs for working with them leave much to be desired. In this talk, we’ll explore useful patterns for making Web Workers easier to work with and highlight effective ways to communicate between workers, handle complex data processing off the main thread, and test and debug them. What are the key takeaways from this talk? - How to use Web Workers to handle complex data processing off the main thread - Patterns and libraries to make working with Web Workers easier - Strategies for testing and debugging Web Workers - Examples of Web Workers being used in real projects Resources: - Web Workers spec: www.w3.org/TR/workers/ - Promise Worker: github.com/nolanlawson/promise-worker - Workerize: github.com/developit/workerize - Greenlet: github.com/developit/greenlet - Lumen: bit.ly/netflix-lumen - Worker DOM: github.com/ampproject/worker-dom - Game of Life Demo: canvas-of-life.glitch.me - Worker Box: github.com/trentmwillis/worker-box Trent Willis (@trentmwillis) is a Senior UI Engineer at Netflix, where he builds tools and applications to give others insight into their applications.
