Demo of web workers integrated with react/webpack through worker-loader

based on react-boilerplate - Boilerplate for "SurviveJS - React"

To run app: npm start

OK - worker is working now, computing something when the component first appears, and when the user clicks on the component.

Issues:

  • ArrayBuffer and Uint32Array are working in this version with the addition of a 'globals' section to .eslintrc, I still don't know if babel-polyfill is required for some browsers, but current version works in the latest for firefox & chrome on mac. Comment directly below about polyfill black magic still applies.

    • in general, I haven't found any decent doc on polyfilling - it seems to be a thing that some people know about but I have no idea how
      to learn the secret - it's just black magic to me. The world could use some clear ground-up doc on how to do fix things up when babel falls over

  • To use the worker, in the last version I did: var Worker = require('worker!./Worker.js');

In this version, loading is working using an es6 "import" statement and the webpack worker-loader.

Now on to including es6-style imports in the worker file itself. This is supposed to work, and is advertised in the worker-loader webpage (https://github.com/webpack/worker-loader). I split out the fibonacci calculation into its own class in a new /utils directory, just to demo the capability. The import fails with this error: SyntaxError: import declarations may only appear at top level of a module I tried including the babel loader a few different ways to work with the worker loader, but couldn't find the formula to fix the error.

Still todo:

  • I was having a problem with reusing ArrayBuffer - it seems like you can only create a buffer, pass it to a worker, and have it passed back once. I tried to use one repeatedly, and got a javascript error - "An ArrayBuffer is neutered and could not be cloned"
