npm install --save-dev gulp-browserify

var gulp = require('gulp');
var browserify = require('gulp-browserify');

// Basic usage
gulp.task('scripts', function() {
	// Single entry point to browserify
	gulp.src('src/js/app.js')
		.pipe(browserify({
		  insertGlobals : true,
		  debug : !gulp.env.production
		}))
		.pipe(gulp.dest('./build/js'))
});

Make sure to pipe only entry points. Browserify will take care of other dependencies for you.

Type : [String || function]

Specifies a pipeline of functions (or module names) through which the browserified bundle will be run. Check out the list of transforms on node-browserify.

If you want to bundle files with extensions other than .js or .json, omit contents from streamed files and set extensions option.

Let's say you want to browserify CoffeeScript, install coffeeify and:

var gulp = require('gulp');
var browserify = require('gulp-browserify');
var rename = require('gulp-rename');

gulp.task('coffee', function() {
  gulp.src('src/coffee/app.coffee', { read: false })
    .pipe(browserify({
      transform: ['coffeeify'],
      extensions: ['.coffee']
    }))
    .pipe(rename('app.js'))
    .pipe(gulp.dest('./build/js'))
});

If you forget { read: false }, gulp-browserify will passes the contents stream of a incoming file to node-browserify. Then node-browserify names the stream as fake_xxx.js and process it. Some transforms such as coffeeify determines whether to transform files with extensions. That is why you need { read: false } for AltJS.

Type : Boolean

Enable source map support. !gulp.env.production would work well.

Type: [String]

Array of extensions that you want to skip in require() calls in addition to .js and .json. Don't forget ..

With { extensions: ['.coffee'] }, you can't do require('app'). Instead, you have to do require('app.coffee').

Type: [String]

Array of paths which should be passed to the ignore function of browserify.

Type: Function

Custom module name resolution function. From node-browserify documentation:

You can give browserify a custom opts.resolve() function or by default it uses browser-resolve.

Obviously, this function must implement the same API as browser-resolve.

Any other options you provide will be passed through to browserify. This is useful for setting things like standalone or ignoreGlobals.

Remove builtins modules defined in lib/builtins.js (browserify module). opts.builtins must be not defined and opts.nobuiltins can be an Array of Strings or simply a String.

gulp.task('scripts', function() {
  gulp.src(['src/index.js'])
    .pipe(browserify({
      nobuiltins: 'events querystring'
    }))
    .pipe(gulp.dest('./build/js'))
});

Example configuration

gulp.task('scripts', function() {
	//single entry point to browserify
	gulp.src(['src/index.js'])
		.pipe(browserify({
		  shim: {
		    angular: {
                path: '/vendor/angular/angular.js',
                exports: 'angular'
		    },
            'angular-route': {
                path: '/vendor/angular-route/angular-route.js',
                exports: 'ngRoute',
                depends: {
                    angular: 'angular'
                }
            }
		  }
		}))
		.pipe(concat('dest.js'))
		.pipe(gulp.dest('./build'))
});

More information about configuring browserify-shim can be found here.

Other than standard Node.js stream events, gulp-browserify emits its own events.

.on('prebundle', function(bundler){})

Event triggered just before invoking bundler.bundle() and provides the bundler object to work with in the callback.

This is especially useful if you want to require(), external() or other methods of node-browserify.

gulp.task('scripts', function() {
  gulp.src('src/js/app.js')
    .pipe(browserify({
      insertGlobals : true,
      debug : !gulp.env.production
    }))
    .on('prebundle', function(bundle) {
      bundle.external('domready');
      bundle.external('react');
    })
    .pipe(gulp.dest('./build/js'))
});

.on('postbundle', function(src){})

Event triggered after the bundle process is over and provides the bundled data as an argument to the callback.
