I'm currently trying to write-up a simple echo server app that echoes back the the request headers when the server receives a GET request. It should look something like this:

Here is my routing code for the request:

app.get('/', function(req,res)
var s = '';
for(var name in req.headers) s += name + ': ' + req.headers[name] + 'n';
res.render('home', output: s));

It results in this response:

It seems that my newline character is not working as intended. I'm sure it's some silly mistake but I can't seem to figure it out.

  Since browser understands html only while rendering, you should use <br /> instead of n to split the lines.

In order to handle the new line character n in html, you have to use the <pre> tag.

The tag defines preformatted text.

Text in a element is displayed in a fixed-width font (usually
Courier), and it preserves both spaces and line breaks.

var values = ['foo', 'bar', 'baz'];

document.getElementById('no-newline').innerHTML = values.join('n');
document.getElementById('newline').innerHTML = values.join('n');

<div id="no-newline"></div>
<pre id="newline"></div>

Otherwise use: <br /> instead of n
