JS implementation of the Twig Templating Language

About

Twig.js is a pure JavaScript implementation of the Twig PHP templating language (http://twig.sensiolabs.org/)

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).

Docs

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

Feature Support

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

Install

Download the latest twig.js release from github: https://github.com/twigjs/twig.js/releases or via NPM:

npm install twig --save

Bower

A bower package is available from philsbury. Please direct any Bower support issues to that repo.

Browser Usage

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

var template = twig({
    data: 'The {{ baked_good }} is a lie.'
});

console.log(
    template.render({baked_good: 'cupcake'})
);
// outputs: "The cupcake is a lie."

Webpack

A loader is available from zimmo.be.

Node Usage (npm)

Tested on node >=6.0.

You can use twig in your app with

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

Usage without Express

If you don't want to use Express, you can render a template with the following method:

import Twig from 'twig';
Twig.renderFile('./path/to/someFile.twig', {foo:'bar'}, (err, html) => {
  html; // compiled string
});

Usage with Express

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

app.js

Express 3

var Twig = require("twig"),
    express = require('express'),
    app = express();

// This section is optional and used to configure twig.
app.set("twig options", {
    allow_async: true, // Allow asynchronous compiling
    strict_variables: false
});

app.get('/', function(req, res){
  res.render('index.twig', {
    message : "Hello World"
  });
});

app.listen(9999);

views/index.twig

Message of the moment: <b>{{ message }}</b>

An Express 2 Example is available on the wiki.
