Nunjucks

Server-side engine met block inheritance, autoescaping, macro's, asynchrone besturing en meer. Zwaar geïnspireerd door jinja2, zeer gelijkaardig aan Twig (php).

Basisgebruik met Express hieronder.

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;
