Section: Crisp talk Technical level: Intermediate Status: Awaiting details


This talk will outlay basics of web workers, their usage in modern web apps, and caveats while implementing them. At the end of the talk, audience will have a idea about when to use web workers, when NOT to use it and how to implement it.


This is a rough mind map of talk topics:

  1. What is a Web Worker ?
  2. When to use it in a modern PWA ?
  3. Under the Hood (Structured cloning algo, transferable objects)
  4. Caveats
  5. Some performance improvements
  6. A real life example of Web Workers
