Load Nodejs Module into A Web Worker

I'm intending to use web worker inside my Node.js application for some concurrent tasks. However since the 'webworker-threads' module follows the implementation of HTML5 web worker, requiring Nodejs modules like require("fs") inside web worker does not work. importScripts() can load js files but I would like a functionality inside the web worker so that I can require npm-installed modules. Is there a workaround for that?

Solution

  • author of webworker-threads here. Thank you for using the module!

    There is a default native_fs_ object with the readFileSync you can use to read files.

    Beyond that, I've mostly relied on onejs to compile all required modules in package.json into a single JS file for importScripts to use, just like one would do when deploying to a client-side web worker environment. (There are also many alternatives to onejs -- browserify, etc.)

    Hope this helps!
