simplifies lazy loading with TypeScript

Availabililty

Status for master

Usage

We recommend the use of TypeScript for best Intellisense

smartsystem supports both npm and SystemJs as module loader.

import { LazyModule } from 'smartsystem'

import * as _myPlugin from 'myPlugin' // plugin does not get loaded here at runtime
let myPluginLazy = new LazyModule<typeof _myPlugin>('myPlugin')
myPluginLazy.setLoader('npm') // sets the loader, defaults to npm anyway

import * as _anotherPlugin from 'anotherPlugin' // plugin does not get loaded here at runtime
let anotherPluginLazy = new LazyModule<typeof _anotherPlugin>('anotherPlugin')
anotherPluginLazy.setLoader('systemjs') // sets the loader to systemjs

myPluginLazy.whenLoaded.then(myPlugin => {
    /* do something with myPlugin. 
       myPlugin receives the typings flow from LazyModule class
       This does NOT load the module during runtime
       The promise whenLoaded will be resolved whenever load() is called for the first time */
})

myPluginLazy.load().then(myPlugin => {
    /* do something with myPlugin. 
       myPlugin receives the typings flow from LazyModule class
       This DOES LOAD the module */
})
