JS port of the Twig templating language.


Twig.js is a pure JavaScript implementation of the Twig PHP templating language (

The goal is to provide a library that is compatible with both browsers and server side JavaScript environments such as node.js.

Twig.js is currently a work in progress and supports a limited subset of the Twig templating language (with more coming).

Documentation is available in the twig.js wiki on Github.

For a list of supported tags/filters/functions/tests see the Implementation Notes page on the wiki.


Download the latest twig.js release from github:

Twig.js can be installed as a bower package with:

bower install twig.js

Include twig.js or twig.min.js in your page, then:

var template = twig({
    data: 'The {{ baked_good }} is a lie.'
    template.render({baked_good: 'cupcake'})
// outputs: "The cupcake is a lie." 

Twig.js can be installed with NPM

npm install twig

You can use twig in your app with

var Twig = require('twig'), // Twig module
    twig = Twig.twig;       // Render function

Twig is compatable with express 2 and 3. You can create an express app using the twig.js templating language by setting the view engine to twig.

Express 3

var Twig = require("twig"),
    express = require('express'),
    app = express();
// This section is optional and used to configure twig. 
app.set("twig options", {
    strict_variables: false
app.get('/', function(req, res){
  res.render('index.twig', {
    message : "Hello World"
Message of the moment: <b>{{ message }}</b>

An Express 2 Example is available on the wiki.
