ColdBrew

django-coldbrew started as a fork of Django Coffeescript.

ColdBrew provides template tags to compile CoffeeScript into JavaScript from templates. It works with both inline code and external files.

Installation

  1. Add "coldbrew" to INSTALLED_APPS setting.
  2. Make sure that you have coffee executable installed. See CoffeeScript official site for details.
  3. Optionally, you can specify the full path to coffee executable with COFFEESCRIPT_EXECUTABLE setting. By default it's set to coffee.

Example Usage

External file

{% load coldbrew %}

<script type="text/javascript"
        src="{{ STATIC_URL}}{% coffeescript "path/to/script.coffee" %}">
</script>

renders to

<script type="text/javascript"
        src="/media/COFFEESCRIPT_CACHE/path/to/script-91ce1f66f583.js">
</script>

Inline

{% load coldbrew %}

<script type="text/javascript">
  {% inlinecoffeescript %}
    console.log "Hello, World!"
  {% endinlinecoffeescript %}
</script>

renders to

  <script type="text/javascript">
    (function() {
  console.log("Hello, World!");
}).call(this);

  </script>

Note that by default compiled files are saved into COFFEESCRIPT_CACHE folder under your STATIC_ROOT (or MEDIA_ROOT if you have no STATIC_ROOT in your settings). You can change this folder name with COLDBREW_CUP setting.
