    A simple HTTP vhost reverse proxy / port sharing implementation for node.js. Run multiple node HTTP servers (Domains, IP's) through one port.

    This project implements a simple HTTP multi domain name / IP / directory HTTP reverse proxy for virtual hosting / port sharing. It simply does what a reverse proxy does combined with some mod_rewrite feature support.

    This project also shows the power of node.js by being implemented in less than 100 lines of code.

    PERFORMANCE NOTICE: This code has NOT been tested in production / high load environments. So be warned and evaluate it on your own before using it in production. Feedback is welcome! (It SHOULD be NOT LESS faster than the http-proxy module implementation.)


    Make sure:

    • node.js is installed (>= 0.8.*)
    • npm is installed


        [sudo] npm install -g port-vhoster


    A valid configuration file for port-vhoster is written in JSON notation as a single object that should provide three key/value pairs:

    • description (String) = Description, printed to the terminal on startup.
    • port (Number) = Source port (share port) to listen to (e.g. 80).
    • vhosts (Object) = Key ($ip OR $domain/port) / value (target $ip:$port/$path)-pairs of vhost-configurations.

    Configuration example

    The following configuration is a simple routing example. You can add more vhosts to the config object too:

            "description": "Routing with port sharing on port 80 (HTTP) for some domains and paths...",
            "port": 80,
            "vhosts": {
                "": "",
                "": "",
                "": "",
                "": ""

    Take a look at the examples directory for more inspiration.


    By default, port-vhoster searches for a config file called port-vhoster.json in current working directory. If you want to use a different name, run port-vhoster with the optional argument to name the config file:

        [sudo] port-vhoster [$alternative-config-file.json]

    You may need super-user permissions if you want port-vhoster to listen to a port below 1024 (e.g. port 80).

    Logging and running in stand-alone mode

    If you're on a Unix/Linux/Mac OS X system you can run port-vhoster in server mode easily:

    Starting (e.g. - don't forget to: chmod +x!):

        echo "Starting port-vhoster..."
        nohup port-vhoster > port-vhoster.out 2> port-vhoster.err < /dev/null &

    Stopping (e.g. - don't forget to: chmod +x!):

        echo "Stopping port-vhoster..."
        kill $(ps aux | grep '[p]ort-vhoster' | awk '{print $2}')

    For sure, server mode and logging may also be possible on Microsoft Windows platform but that's currently untested.
