Node.js - EJS example


Question

I am trying to use Embedded Javascript renderer for node. I installed it using npm, as given here: https://github.com/visionmedia/ejs

And I have the following code, but it does not seem to work:

var connect = require('connect'),
 ejs = require('ejs');

var server = connect.createServer(
    connect.bodyDecoder(),
    connect.methodOverride(),
    connect.staticProvider(__dirname + '/public'),
    function(req,res) {
     ejs.render('hi');
    }
);


server.listen(9000);

Any help greatly appreciated.

Accepted Answer

You need to send something to the response. From the connect hello-world

var connect = require('../../lib/connect');

var server = connect.createServer(function(req, res){
  var body = 'Hello World';
  res.writeHead(200, {
      'Content-Type': 'text/plain'
    , 'Content-Length': body.length
  });
  res.end(body);
});

server.listen(3000);
console.log('Connect server listening on port 3000');

So for your app you'll want to replace:

function(req,res) {
 ejs.render('hi');
}

With something like:

function(req,res) {
  res.writeHead(200, { 'Content-Type': 'text/plain' });
  res.end(ejs.render('hi'));
}

Does that work?

try this: (assuming you have the express and ejs modules installed)

var express = require('express');
var app = express.createServer();
app.configure(function() {
    app.use(express.bodyParser());
    app.use(express.static('./static/'));
    app.use(app.router);
});
app.set('view engine', 'ejs');
app.set('view options', {
    layout: false
});
app.get('/', function(req, res) {
res.render('index', {
    message : 'De groeten'
});
});
app.listen(3000);

and put a view in './views'. call it 'index.ejs' and fill it with some html:

<html>
<head>
<title></title>
</head>

<body>
<p>
<%= message %>
</p>
</body>
</html>

works for me!
