Probably will never use node.js nor Nunjucks for any real development, but now for some reason need:
Nunjucks
node.js
I have done:
node.js
and the npm
(e.g. have node
and the npm
command)mkdir njtest && cd njtest
npm install nunjucks
(got a node_modules/nunjucks
directory)mkdir templates
in the templates i have created two files index.html
and layout.html
with the following jinja2/nunjucks
content
layout.html
<!doctype html>
<head>
<title>simple example</title>
</head>
<body>
<h1>Simple example</h1>
{% block body %}{% endblock %}
</body>
index.html
{% extends "layout.html" %}
{% block body %}
hello world
{% endblock %}
./node_modules/nunjucks/bin/precompile templates >templates.js
and in the templates.js
I have the precompiled code.
What I should to do
next to get an running web-server what will use the precompiled template.js
?
Please, don't search anything advanced behing this question. This is probably an stupid-simple question for someone who know node and javascript.
What i know, will need, create a file let says app.js
and need run it with the node
- but what should contain?
require 'nunjucks';
and probably something like: var res = nunjucks.render('templates.js');
and what else? (the simplest possible (one time) solution). Note: want use Nunjucks server-side and not in the browser.
Nunjucks is rich and powerful template engine for JavaScript. Nunjucks is developed by Mozilla and is maintained by Node JS Foundation. Nunjucks can be used in Node and browser. Its is inspired by Jinja2 ( a web template engine for python ).
Start by initialising your Node application as follows:
cd njtest
npm init
You can hit "Enter" to accept the defaults for most of the questions, if you're doing this after creating app.js then it'll automatically detect this and use it as the entry point for your simple server.
Install Express:
npm install express --save
Then create app.js
as follows:
var express = require( 'express' ),
app = express(),
nunjucks = require( 'nunjucks' ) ;
// Define port to run server on
var port = process.env.PORT || 9000 ;
// Configure Nunjucks
var _templates = process.env.NODE_PATH ? process.env.NODE_PATH + '/templates' : 'templates' ;
nunjucks.configure( _templates, {
autoescape: true,
cache: false,
express: app
} ) ;
// Set Nunjucks as rendering engine for pages with .html suffix
app.engine( 'html', nunjucks.render ) ;
app.set( 'view engine', 'html' ) ;
// Respond to all GET requests by rendering relevant page using Nunjucks
app.get( '/:page', function( req, res ) {
res.render( req.params.page ) ;
} ) ;
// Start server
app.listen( port ) ;
console.log( 'Listening on port %s...', port ) ;
Now fire up a browser, go to http://localhost:9000 and up pops your page!
Hope that helps...
