AsyncTask

Execute tasks on web Workers without seperate files. In browsers without Worker support it fallbacks to iframe.

Nodejs support using child_process is under way.

Install

npm install async-task

Usage

var AsyncTask = require( 'async-task' )

var task = new AsyncTask({
  doInBackground: function( a, b ) {
    return a + b
  }
})

task.execute(1, 2)
  .then(function( result ) {
    result === 3
  })
  .catch( handleException )

API

AsyncTask( options )

Creates a new AsyncTask

options

• options.doInBackground The work(function) to be done in the worker.
• options.keepAlive Keep worker alive so .execute can be called multiple times.

asyncTask.execute( args... ):bluebird/Promise

Execute the doInBackground function with supplied args.

Roadmap

• doInBackground can return a promise or maybe even a generator* so you can iterate over asyncTask.execute
• Nodejs support using child_process
