Jade is an elegant solution to templating and works great on the server combined with Express, but what if you want to use it on the client with a framework like Backbone? Here is a method I have used with success that depends on Stitch:

Server-Side:

// require dependencies
var express = require('express');
var stitch = require('stitch');
var app = module.exports = express.createServer();
var package;
// configure express to use stylus middleware
app.configure(function(){
  app.use(express.bodyParser());
  app.use(express.methodOverride());
  app.set('views', __dirname + '/views');
  app.set('view engine', 'jade');
  app.use(require('stylus').middleware({ src: __dirname + '/public' }));
  app.use(app.router);
  app.use(express.static(__dirname + '/public'));
});
// stitch files together for browser
package = stitch.createPackage({
  paths: [__dirname + '/public/app'], // directory with files to stitch
  compilers: {
    jade: function(module, filename)  {
      var jade = require('jade');
      var source = require('fs').readFileSync(filename, 'utf8');
      source = "module.exports = " + jade.compile(source, {compileDebug : false, client: true}) + ";";
      module._compile(source, filename);
    }
  }
});
// serve stitched files with express from specific path
app.get('/javascripts/application.js', package.createServer());

Client-Side:

// include script https://raw.github.com/visionmedia/jade/master/runtime.js
// include script /javascripts/application.js
var template = require('templates/hello'); // p Hello, #{name}
var context = {name: "World!"};
var content = template(context); // Hello, World!
// or
require('templates/hello')({name: "World!"});
