GulpTaskmodule to compile js with browserify, works good with async.js

var browserify = require('browserify');

var buffer = require('vinyl-buffer');

var gulp = require('gulp');
var sourcemaps = require('gulp-sourcemaps');
var gutil = require('gulp-util');
var gif = require('gulp-if');

        noParse = noParse || [];

        var onError = function (err) {
            gutil.beep();
            gutil.log(err);
            this.emit('end');
        };

        var b = browserify({
            entries: source,
            fast: debug,
            debug: debug,
            noParse: noParse
        });

        var outputName = paths[paths.length-1].split('.').slice(0, -1).join('.');
        var outputPath = paths.slice(0, -1).join('/');

        return b.bundle()
            .on('error', onError)
            .pipe(source_stream(outputName + ".js"))
