A simple asset manager middleware for connect

Bundle up!

Bundle up is a middleware for connect to manage all client-side assets in an organized way. Everything is manged using an assets file

// assets.js
module.exports = function(assets) {
    assets.root = __dirname


Just point to a file (.js, .css, .coffee or .styl are currently supported) anywhere in your app directory. In your view you can then just render all the css or javascript files by calling renderStyles and renderJs like this:

    != renderStyles
  body!= body
  != renderJs

By default this will render

<link href='/bootstrap/bootstrap.min.css' media='screen' rel='stylesheet' type='text/css'/>
<link href='/generated/app/styles/screen.css' media='screen' rel='stylesheet' type='text/css'/>

<script src='/js/jquery-1.6.4.min.js' type='text/javascript'></script>
<script src='/js/jquery.placeholder.min.js' type='text/javascript'></script>
<script src='/generated/app/client/main.js' type='text/javascript'></script>

All assets will be compiled on-the-fly when bundle:false is set. Therefore the server never needs to be restarted when editing the different assets.

To render bundles bundle:true needs to be passed as a parameter to the middleware. This will concatenate all javascript and css files into bundles and render this:

<link href='/generated/bundle/d7aa56c_global.css' media='screen' rel='stylesheet' type='text/css'/>
<script src='/generated/bundle/1e4b515_global.js' type='text/javascript'></script>

All bundles are generated during startup. The filename will change with the content so you should configure your web server with far future expiry headers.

All files that needs to be compiled, copied (if you are bundling up a file that doesn't reside in your public/ directory) or bundled will end up in public/generated/ directory. This is to have an organized way to separate whats actually your code and whats generated code.

BundleUp(app, __dirname + "/assets", {
  staticRoot: __dirname + "/public/",

The first parameter is the app object and the second is the path to the assets file

  • Add support for addCss("folder/*.css") and addJs("**.coffee") etc.
  • Add support for namespaced assets
