This project is a mostly a convenience wrapper around the original mustache.js (Thanks @janl !).

Added Bonus Features

Support for Express.js

This project will plug right in to Express.js as a view engine. Just add this project as a dependency to your Express application, then configure your app like so:

var express = require("express"),
    mustachio = require("mustachio"),
    app = express.createServer();

app.configure(function() {
  // ...
  app.register('.mustache', mustachio);
  app.set('view engine', 'mustache');
  // ...

Caveat: due to a bug in older versions of Express, Mustachio will only work with versions 2.2.2+.

Express Partials

When using Express, Mustachio supports Express' partial file lookup, so using Mustache's partial syntax should just work. For example, if you put this in your template: {{> rad }}, you could put your partial template in any of these places:


File lookup is performed in the above order.

View Helper Objects !!!

The one really killer feature of this project is it's support for view helper objects. View helper objects allow you to keep your view-rendering logic truly isolated by providing a space for all of your view-specific logic. This keeps your request handlers/controllers clean of view-specific code.

When your template is loaded ("myview.mustache", for instance), we also check for a corresponding helper file to load (such as "myview.mustache**.js**").



Name: {{ name }} - Age: {{ age }}


module.exports = {
  name: function() {
    return this.first + " " + this.last;

Now let's render that from within express:

app.get('/', function(req, res){
  res.render("myview", {
    first: "Dan",
    last: "Dean",
    age: 5000

Our template will get rendered using our god damned amazing helper!

Name: Dan Dean - Age: 5000

View Helper Scope

One thing to note is how view helper scope works. View helpers only work on their associated views, and are not inherited by parent or child views.
