Templating with CoffeeScript


With NPM for Node.js

Note: Because of incompatibility with Ender.js the dependence on CoffeeScript will not be installed automatically.

# npm install coffeete coffee-script

Or with Ender.js for the browser

# ender build coffeete


It is very simple and very lightweight. It uses the CoffeeScript compiler for string interpolation. The tool chain: CoffeeTe → CoffeeScript → JavaScript.


Our template

<script id="about-me" type="text/x-coffeete">
  <h1>#{cap name}</h1>
    !{for hobby, i in hobbies
      <li class="#{if i % 2 then 'even' else 'odd'}">

The view data

var view = {
      name: "christopher"
    , about: "I like grapefriut."
    , hobbies: ["Computers", "Martial Arts", "Coffee"]
    , cap: function (str) {
      return str.slice(0,1).toUpperCase()+str.slice(1);

In the browser

var str = document.getElementById('about-me').text
  // Compile a CoffeeTe string to a template function ready to recieve data. 
  , template = coffeete(str)
  // Run our compiled template with the view data to get a ready HTML string. 
  , html = template(view);
// Fill the page with our newly rendered HTML. 
document.getElementsByTagName('body')[0].innerHTML += html;

With Node.js

var str = fs.readFileSync('about-me.chtml').toString()
  , template = coffeete(str)
  , html = template(view);
// Write to a static HTML file or serve directly over HTTP. 
fs.writeFile('about-me.html', html);

Or use the .coffeete file extension to automatically compile your template. Now importing your about-me.coffeete can be done with require.

var template = require('./about-me')
  , html = template(view);
fs.writeFile('about-me.html', html);

The result

  I like grapefriut.
    <li class="odd">
    <li class="even">
      Martial Arts
    <li class="odd">


The downside, specialy when running in the browser, is the dependency on CoffeeScript at runtime and the need to compile your CoffeeTe templates runtime. Therfore you can pre compile your templates into pure JavaScript and save them as CommonJS compliant modules.

# npm install -g coffeete coffee-script

Now we have installed the CoffeeTe CLI globaly.

# coffeete about-me.chtml > about-me.js

Or, if you prefere.

# cat about-me.chtml | coffeete > about-me.js
