Node.js subdomains

Question

I'm trying to get my Node.js powered site to run on one instance serving multiple domains. I have my main domain, example.com and then I have admin.example.com and api.example.com which all have different routes etc, I'm using Express.

So far I've added two A records for the subdomains, and also added two entries into /var/vhosts on my CentOS box.

127.0.0.1 api.example.com
127.0.0.1 admin.example.com
127.0.0.1 example.com

I'm aware that Express has a express.vhost method so I've already tried:

app.use(express.vhost('api.example.com', require('./lib/subdomains/api')))
app.use(express.vhost('admin.example.com', require('./lib/subdomains/admin')))

But that still only serves my main routes which is imported below. What am I missing?

Answer 1

If anybody else finds this question, you might want to check that you're passing your vhost route parameters the right way around.

I was using:

app.get('/', function(res, req) { /* Do stuff.. */ }

When it should be. The first argument for the callback function is req, then the second one is res.

app.get('/', function(req, res) { /* Do stuff.. */ }

Be diligent with your code :)
