Jsdom: Support for Web Workers?

Created on 19 Oct 2017 · 4Comments · Source: jsdom/jsdom

Basic info:

Node.js version: v8.6.0
jsdom version: 11.3.0

Minimal reproduction case

const { JSDOM } = require("jsdom");

const options = {
  url: "http://example.com/",
};
const dom = new JSDOM(`
  <!DOCTYPE html><html><head></head><body></div></body></html>
`, options);

var w = new dom.window.Worker("demo_workers.js");

var w = new dom.window.Worker("demo_workers.js");
        ^

TypeError: dom.window.Worker is not a constructor
    at Object.<anonymous> (/Users/andrew/projects/swagger-linter/no-worker.js:10:9)
    at Module._compile (module.js:624:30)
    at Object.Module._extensions..js (module.js:635:10)
    at Module.load (module.js:545:32)

    at Function.Module.runMain (module.js:665:10)
    at startup (bootstrap_node.js:187:16)
    at bootstrap_node.js:607:3

How does similar code behave in browsers?

You'd probably get the error that the file doesn't exist but Worker would be defined.

Now that node supports the worker threads API should this be investigated again?

Can people refrain from adding +1 comments? They are not helpful.

Fixing this will depend on Worker support in Node.js core, which is already supported by Ayo.js but yet to be backmerged into Node.js. Both the primary author of the feature and I are unfortunately short on time to make this happen soon.
