gulp - laravel elixir - combine compiled coffeescript/browserify files with sourcemaps -

i trying compile coffeescript code 1 file , browserify another, combine them. works fine , each file gets source-map in build directory, can't combine them while generating combined source-map.

any way of doing elixir or need gulp pipe chain?

elixir(function(mix){ mix.browserify(['vendor-modules.js'], 'resources/assets/js/build/vendor-modules.js')     .coffee([         '_classes/*.coffee',          'main.coffee',          'react/home/*.coffee',         'react/home.coffee',     ], 'resources/assets/js/build/app-main.js')     .scripts([         'build/vendor-modules.js',         'build/app-main.js',     ], 'public/assets/js/app.js'); });
