Multithread-it NPM

Multithread-it

A components oriented virtual dom in a worker rendering solution

Multithread-it help you writing web components wich do not block UI. This component will be rendered in a web-worker.

Components are written with virtual-dom and JSX.

Events are propagated from the UI thread to the application worker using an abstraction over Redux.

Example

Your component is the composition of two elements.

A Component working in the application WebWorker

import { MultithreadItComponent } from 'multithread-it';

class Component extends MultithreadItComponent {
  _label; 

  onInit() {
    this.watch(
      state => state.label,
      label => this._label = label
    );
  }

  render() {
    return (
      <div>
        {this._label}
        <button data-click="EVENT_CLICK">-</button>
      </div>
    );
  }
}

An EventsHandlers listening to component events in the UI-thread

import { MultithreadItEventsHandler } from 'multithread-it';

class EventsHandlers  extends MultithreadItEventsHandler {
  constructor(workerStore) {
    super(workerStore);

    this.addEventHandlers(
      'click',
      e => this._click(e)
    );
  }

    _click(e) {
    const target = e.target;
    if (target['data-click'] === 'EVENT_CLICK') {
      e.preventDefault();
      this._worker.dispatchEvent('click', 'clicked');
    }
  }
}

Then, in the application WebWorker a Redux reducer will process events.

function label(state = 'Initialized', action) {
  switch (action.type) {
    case 'click':
      return state = action.data;
    default:
      return state;
  }
}
