a server side mustache.js example using node.js

Question

I'm looking for an example using Mustachejs with Nodejs

here is my example but it is not working. Mustache is undefined. I'm using Mustachejs from the master branch.

var sys = require('sys');
var m = require("./mustache");

var view = {
  title: "Joe",
  calc: function() {
    return 2 + 4;
  }
};    
var template = "{{title}} spends {{calc}}";    
var html = Mustache().to_html(template, view);

sys.puts(html);

Answer 1

I got your example working by installing mustache via npm, using the correct require syntax and (as Derek said) using mustache as an object not a function

npm install mustache

then

var sys = require('sys');
var mustache = require('mustache');

var view = {
  title: "Joe",
  calc: function() {
    return 2 + 4;
  }
};

var template = "{{title}} spends {{calc}}";

var html = mustache.to_html(template, view);

sys.puts(html);

Your example is almost correct. Mustache is an object, not a function, so it doesn't need the (). Rewritten as

var html = Mustache.to_html(template, view);

will make it happier.

Thanks to Boldr http://boldr.net/create-a-web-app-with-node Had to add the following code to mustache.js

for (var name in Mustache)
    if (Object.prototype.hasOwnProperty.call(Mustache, name))
        exports[name] = Mustache[name];

Not exactly sure what it is doing but it works. Will try to understand it now.

It basically adds everything in the Mustache object to the [special] exports object. This is necessary as this is how modules work in node.js nodejs.org/docs/v0.4.8/api/modules.html#modules – Orthogenic

Answer 4

Take a look to A Gentle Introduction to Node.js

To fix I opened up mustache.js and removed the var declaration when Mustache is being created
