Можно с помощью gulp + webpack или gulp + browserify или просто webpack.

Вот что использую я gulp + webpack:

let gulp = require('gulp');
    let webpackStream = require('webpack-stream');
    let webpack = webpackStream.webpack;
    let named = require('vinyl-named');

    const scripts = {
        test: /\.js$/,
        exclude: [/develop\/app/,],
        query:{
            presets: ['es2015']
        },
        loader: 'babel-loader'
    };

    const annotate = {
        test: /\.js$/,
        loader: 'ng-annotate'
    }

    const markup = {
        test: /\.html$/,
        loader: 'ngtemplate!html'
    };

    const uglify = {
        test: /\.js$/,
        loader: 'uglify'
    };

    let config = {
        devtool: 'sourcemap',
        module: {
            loaders: [uglify, scripts, annotate, markup]
        },
        plugins: [
            new webpack.NoErrorsPlugin()
        ]
    };

   gulp.task('buildModules', function(){
        return gulp.src('develop/app/myModule.js')
            .pipe(named())
            .pipe(webpackStream(config))
            .pipe(gulp.dest('build/app'))
    };
