Transparent file compilation and dependency management for Node's connect framework in the spirit of the Rails 3.1 asset pipeline.
.coffee(CoffeeScript) files as compiled
.jstogether using Snockets
.styl(Stylus) as compiled
- Serve files with an MD5 hash suffix and use a far-future expires header for maximum efficiency
- Avoid redundant git diffs by storing compiled
.cssfiles in memory rather than writing them to the disk—except when you want them (e.g. for deployment to a CDN).
First, install it in your project's directory:
npm install connect-assets
Also install any specific compilers you'll need, e.g.:
npm install coffee-script npm install stylus npm install nib npm install bootstrap-stylus
Then add this line to your app's configuration:
Finally, create an
assets directory in your project and throw all your
.coffee files in /assets/js and
.styl files in /assets/css.
connect-assets provides two global functions named
css. Use them in your views. They tell connect-assets to do any necessary compilation, then return the markup you need. For instance, in a Jade template, the code
!= css('normalize') != js('jquery')
(where `!= is Jade's syntax for running JS and displaying its output) results in the markup
<link rel='stylesheet' href='/css/normalize.css'> <script src='/js/jquery.js'></script>
You can indicate dependencies in your CoffeeScript files using the Sprockets-style syntax
#= require dependency
js function at that file, two things can happen:
- By default, you'll get multiple
<script>tags out, in an order that gives you all of your dependencies.
- If you passed the
build: trueoption to connect-assets (enabled by default when
If you want to bring in a whole folder of scripts, use
#= require_tree dir
See Snockets for more information.
Note: CSS concatenation is not supported by connect-assets directly, because Stylus already does a fine job of this. Stylus is basically a superset of CSS, so just rename your
.css files to
.styl and learn about its @import syntax.
If you like, you can pass any of these options to the function returned by
'assets'): The directory assets will be read from
global): The object the
jshelper functions will attach to
- ... see the source (
src/assets.coffee) for more.
You can also set the "root path" on the
js helper functions (by default,
To override these roots, start a path with
'/'. So, for instance,
<link rel='stylesheet' href='/css/style.css'>
<link rel='stylesheet' href='/style.css'>
