vhost

Previously connect.vhost().

Install

$ npm install vhost

API

var vhost = require('vhost')

vhost(hostname, server)

Create a new middleware function to hand off request to server when the incoming host for the request matches hostname.

hostname can be a string or a RegExp object. When hostname is a string it can contain * to match 1 or more characters in that section of the hostname. When hostname is a RegExp, it will be forced to case-insensitive (since hostnames are) and will be forced to match based on the start and end of the hostname.

When host is matched and the request is sent down to a vhost handler, the req.vhost property will be populated with an object. This object will have numeric properties corresponding to each wildcard (or capture group if RegExp object provided) and the hostname that was matched.

// for match of "foo.bar.example.com:8080" against "*.*.example.com":
req.vhost.host === 'foo.bar.example.com:8080'
req.vhost.hostname === 'foo.bar.example.com'
req.vhost.length === 2
req.vhost[0] === 'foo'
req.vhost[1] === 'bar'

Examples

using with connect for static serving

var connect = require('connect')
var serveStatic = require('serve-static')
var vhost = require('vhost')

var mailapp = connect()

// add middlewares to mailapp for mail.example.com

// create app to serve static files on subdomain
var staticapp = connect()
staticapp.use(serveStatic('public'))

// create main app
var app = connect()

// add vhost routing to main app for mail
app.use(vhost('mail.example.com', mailapp))

// route static assets for "assets-*" subdomain to get
// around max host connections limit on browsers
app.use(vhost('assets-*.example.com', staticapp))

// add middlewares and main usage to app

app.listen(3000)

using with connect for user subdomains

var connect = require('connect')
var serveStatic = require('serve-static')
var vhost = require('vhost')

var mainapp = connect()

// add middlewares to mainapp for the main web site

// create app that will server user content from public/{username}/
var userapp = connect()

userapp.user(function(req, res, next){
  var username = req.vhost[0] // username is the "*"

  // pretend request was for /{username}/* for file serving
  req.originalUrl = req.url
  req.url = '/' + username + req.url

  next()
})
userapp.use(serveStatic('public'))

// create main app
var app = connect()

// add vhost routing for main app
app.use(vhost('userpages.local', mainapp))
app.use(vhost('www.userpages.local', mainapp))

// listen on all subdomains for user pages
app.use(vhost('*.userpages.local', userapp)

app.listen(3000)
