##Intro
express-subdomain-handler takes the headache out of dynamic subdomain routing in Express. It captures the contents of any
subdomain and writes them into the Express req.url. This means you can write specific route handlers for subdomain urls.
As you can see below, express-subdomain-handler can manage single or multiple subdomains.
##Examples
http://mysubdomain.example.com
=> '/subdomain/mysubdomain/'
http://myexcellentsubdom.example.com/homepage
=> '/subdomain/myexcellentsubdom/homepage'
http://first.second.example.com
=> '/subdomain/first/second/'
http://first.second.example.com/another/page
=> '/subdomain/first/second/another/page'
##Installation
npm install express-subdomain-handler
##Usage
Add express-subdomain-handler to your express middleware stack (before your routes are specified). You need to specify
what the base url of your site is ('example.com', 'example.local', etc), what you what subdomain urls to be prefixed with
('subdomain' by default) and whether you want logging turned on (false by default)
app.use( require('express-subdomain-handler')({ baseUrl: 'example.com', prefix: 'myprefix', logger: true }) );
Setup routes to catch subdomain urls so for http://mysubdomain.example.com/homepage
I would write my route
handler to look like this.
app.get('/myprefix/:thesubdomain/thepage', function(req, res, next){
// for the example url this will print 'mysubdomain'
res.send(req.params.thesubdomain);
});
