bundling and minification - How can you bundle Angular 2 using System JS Builder? -

i'm using system js system js builder bundle application, assets, , libraries references. problem can bundle libraries referenced explicitly in index.html, e.g:

<script src="node_modules/es6-shim/es6-shim.min.js"></script> <script src="node_modules/zone.js/dist/zone.js"></script> <script src="node_modules/reflect-metadata/reflect.js"></script> <script src="node_modules/systemjs/dist/system.src.js"></script> 

however, can't figure out how can bundle angular 2 itself, or @ least modules required angular 2, aren't referenced in html. how can done?

using systemjs-builder can bundle angular 2 app code , bundle other libraries separately.

i bundled library reference directly in html vendors.min.js, , library referenced through system.config.js plus app code app.min.js. in example can see dependencies in tour of heroes loaded page in <10 network requests (source code).

// bundle dependencies vendors file gulp.task('bundle:libs', function () {     return gulp.src([         'node_modules/jquery/dist/jquery.min.js',         'node_modules/bootstrap/dist/js/bootstrap.min.js',         'node_modules/semantic-ui/dist/semantic.min.js',         'node_modules/es6-shim/es6-shim.min.js',         'node_modules/es6-promise/dist/es6-promise.min.js',         'node_modules/systemjs/dist/system.src.js',         'system.config.js',       ])         .pipe(concat('vendors.min.js'))         .pipe(uglify())         .pipe(gulp.dest('public/lib/js')); });  // compile typescript js gulp.task('compile:ts', function () {   return gulp     .src([         "src/**/*.ts",         "typings/*.d.ts"     ])     .pipe(sourcemaps.init())     .pipe(tsc({         "module": "system",         "moduleresolution": "node",         "outdir": "public/dist/js",         "target": "es5"     }))     .pipe(sourcemaps.write('.'))     .pipe(gulp.dest('public/dist')); });  // generate systemjs-based builds gulp.task('bundle:js', function() {   var builder = new sysbuilder('public', './system.config.js');   return builder.buildstatic('app', 'public/dist/js/app.min.js'); });  // minify js bundle gulp.task('minify:js', function() {   return gulp     .src('public/dist/js/app.min.js')     .pipe(uglify())     .pipe(gulp.dest('public/dist/js')); });  gulp.task('scripts', ['compile:ts', 'bundle:js', 'minify:js']);
