NodeJS Template frameworks


Server-side engine with block inheritance, autoescaping, macros, asynchronous control, and more. Heavily inspired by jinja2, very similar to Twig (php).

Docs - http://mozilla.github.io/nunjucks/
Install - npm i nunjucks

Basic usage with Express below.
app.js

var express = require ('express');
var nunjucks = require('nunjucks');
var app = express();
app.use(express.static('/public'));
// Apply nunjucks and add custom filter and function (for example).
var env = nunjucks.configure(['views/'], { // set folders with templates
 autoescape: true,
 express: app
});
env.addFilter('myFilter', function(obj, arg1, arg2) {
 console.log('myFilter', obj, arg1, arg2);
 // Do smth with obj
 return obj;
});
env.addGlobal('myFunc', function(obj, arg1) {
 console.log('myFunc', obj, arg1);
 // Do smth with obj
 return obj;
});
app.get('/', function(req, res){
 res.render('index.html', {title: 'Main page'});
});
app.get('/foo', function(req, res){
 res.locals.smthVar = 'This is Sparta!';
 res.render('foo.html', {title: 'Foo page'});
});
app.listen(3000, function() {
 console.log('Example app listening on port 3000...');
});

/views/index.html

<html>
<head>
 <title>Nunjucks example</title>
</head>
<body>
{% block content %}
{{title}}
{% endblock %}
</body>
</html>

/views/foo.html

{% extends "index.html" %}
{# This is comment #}
{% block content %}
 <h1>{{title}}</h1>
 {# apply custom function and next build-in and custom filters #}
 {{ myFunc(smthVar) | lower | myFilter(5, 'abc') }}
{% endblock %}
