var browserify = require('browserify');
var source = require('vinyl-source-stream');

  var bundler = browserify({
    entries: ['./app/scripts/app.js'],
    debug: true,
    transform: ['reactify', 'debowerify']
  });

  return bundler
    .plugin('minifyify', {

      output: 'dist/scripts/bundle.map.json'
    })
    .bundle()
