Django template tags to compile CoffeeScript

Primary LanguagePythonOtherNOASSERTION

Django CoffeeScript

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

Installation

  1. Add "coffeescript" 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.
  4. In case you use Django’s staticfiles contrib app you have to add django-coffeescript’s file finder to the STATICFILES_FINDERS setting, for example :
STATICFILES_FINDERS = (
    'django.contrib.staticfiles.finders.FileSystemFinder',
    'django.contrib.staticfiles.finders.AppDirectoriesFinder',
    # other finders..
    'coffeescript.finders.CoffeescriptFinder',
)

Example Usage

Inline

{% load coffeescript %}

<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>

External file

{% load coffeescript %}

<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>

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 COFFEESCRIPT_ROOT and COFFEESCRIPT_OUTPUT_DIR settings.
