Welcome to PRODROMUS, a very tiny XMPP client.

"Hey there, I'm PRODROMUS, a very simple XMPP messaging client, mainly reasonable as contact form replacement/supplement or support contact utility."

"Prodromus" is Latin and means as much as "express messenger", "courier". Prodromus makes use of the great Strophe.js library. It also uses jQuery.

Visit the projekt wiki for more information as well as a screencast.


The client itself only requires JavaScript and a BOSH endpoint. The endpoint has to be reachable on the same domain as PRODROMUS was accessed due to JavaScript cross-domain restrictions. The simplest way is to set up a reverse proxy with Apache's mod_proxy - see the contents/example.htaccess example file.

Another requirement is a XMPP server with SASL anonymous enabled.


  1. Download PRODROMUS.
  2. Copy the files to your web server.
  3. Ensure a BOSH endpoint / connection manager is accessible under the same domain you access PRODROMUS. If you're using Apache you can enable mod_proxy, rename the source:contents/htaccess.sample to .htaccess and adjust the URL of your BOSH-Service. ejabberd, for example, already comes with built-in BOSH support.
  4. Open contents/prodromus.js and configure PRODROMUS to fit your needs. The following values are important: XMPP_SERVER, BOSH_SERVICE and RECEIVER. You can also configure the date format and language, currently English ("en") and German ("de") are supported.
  5. You should be ready to go. Try it by opening prodromus.html in your browser. You can integrate PRODROMUS into your website later.
