Can I load AMD modules inside a webworker?

I am trying out webworkers for making my computationally heavy Javascript truly parallel. However, I have a problem in that all of my javascript files are AMD modules. Can I use requirejs inside of my webworker? How?

Solution

  • In Web workers, other scripts can be loaded using the importScripts function. The source code of RequireJS shows that Web workers are also supported:

    // Line 23:
isWebWorker = !isBrowser && typeof importScripts !== 'undefined',
// Line 1877:
} else if (isWebWorker) {
    //In a web worker, use importScripts. This is not a very
    //efficient use of importScripts, importScripts will block until
    //its script is downloaded and evaluated. However, if web workers
    //are in play, the expectation that a build has been done so that
    //only one script needs to be loaded anyway. This may need to be
    //reevaluated if other use cases become common.
    importScripts(url);
