Standard rxjs operators built to run in web workers

rxjs-worker

RXJS extensions for adding web worker functionality via operators and observables

Observables

observable.fromWorker()

Create an observable from a webworker, path, or function

// web worker
const myWorker = new Worker('path/to/web-worker.js');
const observable1 = Observable.fromWorker(myWorker);

// function
const observable2 = Observable.fromWorker(() => {
  self.postMessage('Hello World');
});

// string
const observable3 = Observable.fromWorker('path/to/web-worker.js');

Operators

observable.mapWorker()

simple map function that runs in a web worker

Observable
  .from(['Hello World'])
  .mapWorker(strng => {
    return strng + ', I am from a worker.';
  })
  .subscribe(res => {
    console.log(res); // Hello World, I am from a worker
  });

observable.filterWorker()

returns either the result or null

Observable
  .from(['Hello World'])
  .filterWorker(strng => {
    return strng === 'Hello World';
  })
  .subscribe(res => {
    console.log(res); // Hello World
  });
