Run tasks in background in NativeScript

Issue

I am using NativeScript 2.0 and I am developing an Android module that is NOT allowed to be run in the main thread!

Is there a module that I can use to run a function in a background thread?

Or is it possible to use something like AsyncTask class in "native" JavaScript code (NOT TypeScript!)?

Solution

nativescript added web workers. https://docs.nativescript.org/angular/core-concepts/multithreading-model.html

var worker = new Worker('myWorker');
worker.postMessage('hello');
worker.onmessage = function(msg) {
      console.log('answer from worker',msg.data);
}

in worker myWorker.js

    require('globals'); // necessary to bootstrap tns modules on the new thread
    onmessage = function(msg) {
        postMessage('bye');
    }
