Strobe Templates is a part of a larger Node.js framework I’m working on.
The template syntax is the same as in Django templates.

For now, Strobe Templates have the following template tags:

{% for x in y %}{% endfor %}
{% if x %}{% else if y %}{% else %}{% endif %}
{% extends template_name %}
{% include template_name %}
{% block block_name %}

You can define your own template tags in the “tags.js” module. Template inheritance is done in the same way as Django, only in an asynchronous way. Strobe templates support caching of parsed templates.
One important difference from Django templates is that the render() method returns an array of strings. It’s your job to call .join("") on the rendered output.

Requirements

• node.js >= 0.1.95 (works with lesser versions if you remove the buffer.toString in the load method of the template prototype)

Simple usage example:

var sys = require('sys')
  , templates = require('template');

templates.setTemplatesDir('/path/to/templates/dir');
templates.setDebug(false);

var context = { foo: 1, bar: 2 };
var template = new templates.Template('path/to/template.html');
template.load( function( err, template ) {
  if( err ) // load/parse errors (invalid filename, bad template syntax)
    sys.puts( err );
  else
    template.render( context, function( err, output ) {
      if( err ) // render errors (invalid filename in context variables, bad context variables)
        sys.puts( err );
      else 
        sys.puts( output.join("") );
    });
});

Adding some default values to all context instances (Something like a context_processor in Django)

var Context = require('template').Context;
// This will be available in all context insances
Context.addToDefault({ MEDIA_URL: "http://media.url/" });
// Clear the defaults
Context.clearDefault();

Run a benchmark and a test output:

$ node tests/run.js

Used Code

• Visionmedia’s ext library (extensions to Object and sprintf )

Todos

• Add filters for variable tags
