Writing Tasks

Writing tasks is as easy as:

• Your task must export an uberclass
• Your class when instantiated must accept one argument, “callback” which should be fired when
  • Processing has finished and there is no error
  • Processing has hit an error before finishing

Below is an example from the “backend-example-module”

ExampleTask from the “backend-example-module”

var Class = require( 'uberclass' )
  , async = require( 'async' )
  , debug = require( 'debug' )( 'ExampleTask' );
var ExampleTask = module.exports = Class.extend(

{

    init: function( callback ) {

      debug( ‘Starting…’ );
async.parallel([
this.proxy( ‘doSomething’ ),
this.proxy( ‘doSomethingElse’)
],
function(err, results){
debug( ‘Finished.’ );
callback( err );
});
},

doSomething: function( callback ) {
callback( null );
},

doSomethingElse: function( callback ) {
callback( null );
}
});
