Chrome can't load web worker

Chrome doesn't let you load web workers when running scripts from a local file.

I use a workaround. Chrome blocks Worker but not <script>. Hence the best way to make a universal solution is this:

function worker_function() {
    // all code here
}
// This is in case of normal worker start
// "window" is not defined in web worker
// so if you load this file directly using `new Worker`
// the worker code will still execute properly
if(window!=self)
  worker_function();

You then link it as normal <script src="...". And once the function is defined, you use this abomination of a code:

new Worker(URL.createObjectURL(new Blob(["("+worker_function.toString()+")()"], {type: 'text/javascript'})));

The problem has been properly explained by Noble Chicken but I have a more general solution for it. Instead of installing wamp or xamp, with python you can navigate to the folder your project is hosted in and type: python -m http.server

Just that and you will have a running server on that folder, reachable from localhost.
