BITS Lazy Load

This module provides the ability to have a soft dependency on another module.

Use

const LazyLoad = require('@lgslabs/bits-lazy-load');
const MODULE_NAME = 'some-other-module';

class MyClass() {
  constructor() {
    this._boundOnLoaded = this._onLoaded.bind(this);
    this._boundOnUnloaded = this._onUnloaded.bind(this);
    this._lazyLoad = null;
  }

  load({messageCenter}) {
    this._lazyLoad = new LazyLoad();
    return Promise.resolve()
    .then(() => this._lazyLoad.load({
      messageCenter,
      moduleName: MODULE_NAME,
      onLoaded: this._boundOnLoaded,
      onUnloaded: this._boundOnUnloaded,
    }));
  }

  unload({messageCenter}) {
    return Promise.resolve()
    .then(() => this._lazyLoad.unload());
  }

  _onLoaded(messageCenter) {
    // when the module is loaded, do something
  }

  _onUnloaded(messageCenter) {
    // when the module is unloaded, do something
  }
}
