POExpressJS Server - How to handle multiple domains
text
Body
copied!<p>I'm fooling around a little with Express and I'm wondering, what the "most correct" way is to handle multiple domains which are linked to the same server.</p> <p>Lets assume we have </p> <ul> <li>foo.com</li> <li>bar.net</li> <li>baz.com</li> </ul> <p>which all point to <code>111.222.333.444</code>. That machine is running NodeJS with Express. My current solution looks like this:</p> <pre><code>var express = require( 'express' ), app = module.exports = express.createServer(), // ... more lines ... app.get( '/', routes.index.bind( app ) ); </code></pre> <p>Thus far this is pretty straightforward. The only exception so far is in my <code>app.configure</code> call, where I didn't make a call to <code>.use( express.static() )</code>. Thats because the <code>.routes.index()</code> method looks like so right now:</p> <pre><code>var fs = require( 'fs' ), // ... more lines ... exports.index = function( req, res ) { var host = /(\w+\.)?(.*)\.\w+/.exec( req.header( 'host' ) ), app = this; switch( host[ 2 ] ) { case 'foo': app.use( express.static( '/var/www/foo' ) ); fs.readFile( '/var/www/foo/index.html', 'utf8', fileReadFoo ); break; case 'bar': app.use( express.static( '/var/www/bar' ) ); fs.readFile( '/var/www/bar/index.html', 'utf8', fileReadBar ); break; case 'baz': // ... lines ... res.render( 'index', { title: 'Baz Title example' } ); break; default: res.send('Sorry, I do not know how to handle that domain.'); } function fileReadFoo( err, text ) { res.send( text ); } function fileReadBar( err, text ) { res.send( text ); } }; </code></pre> <p>What happens here is, that I analyse the <code>req.header</code> for the <code>host</code> entry and parse the domain name. Based on that, I call the <code>.static()</code> method so <em>Express</em> can serve the right static resources etc., furthermore, I just simply read and send the contents of the <em>index.html</em> files. I tried to use <em>Jade</em> aswell for serving plain <em>HTML files</em>, but the <code>include</code> directive in <em>Jade</em> only accepts relative pathes.</p> <p>However, this indeed works, but I'm pretty unsure if that is a good practice. </p> <p>Any advice / help welcome.</p> <hr> <p><strong>Update</strong></p> <p>I think I need to make this more clear. I'm not a beginner by any means. I'm very aware how ES works and other servers like NGINX. I'm looking for qualified answers on what the right thing with NodeJS/Express is. If it doesn't make any sense to use Node/Express for that, please elaborate. If there is a better way to do this with Node/Express, please explain.</p> <p>Thanks :-)</p>
