Hogan.js is a compiler for the Mustache templating language. For information on Mustache, see the manpage and the spec.
Hogan compiles templates to HoganTemplate objects, which have a render method.
var data = {
screenName: "dhg",
};
var template = Hogan.compile("Follow @{{screenName}}.");
var output = template.render(data);
// prints "Follow @dhg."
console.log(output);
Hogan is fast--try it on your workload.
Hogan has separate scanning, parsing and code generation phases. This way it's possible to add new features without touching the scanner at all, and many different code generation techniques can be tried without changing the parser.
Hogan exposes scan and parse methods. These can be useful for pre-processing templates on the server.
var text = "{{^check}}{{#i18n}}No{{/i18n}}{{/check}}";
text += "{{#check}}{{#i18n}}Yes{{/i18n}}{{/check}}";
var tree = Hogan.parse(Hogan.scan(text));
// outputs "# check"
console.log(tree[0].tag + " " + tree[0].name);
// outputs "Yes"
console.log(tree[1].nodes[0].nodes[0]);
It's also possible to use HoganTemplate objects without the Hogan compiler present. That means you can pre-compile your templates on the server, and avoid shipping the compiler. However, the optional lambda features from the Mustache spec do require the compiler to be present.
Why another templating library?
Hogan.js was written to meet three templating library requirements: good performance, standalone template objects, and a parser API.
