# FASI

Fast And Sleek Invite (FASI)

## About

FASI is an HTML invite page for XMPP.
The main purpose, is to provide an interface to share XMPP contacts via HTML
browsers.
It also provides an interface to explore XMPP server conferences, pubsub and
other services.

### Reasons for creating FASI

The main reasons for the realization of FASI are to:

- Add interactive capabilities, as well as vCard information;
- Create rapport with the viewers, by displaying vCard information, such as Full
  Name and Description or Note;
- Realize the beautiful simplicity of XMPP, so that more people would be
  motivated to utilize, install, serve, and develop XMPP software;
- Charm our "normie" friends, so called, by displaying an attractive contact
  HTML page, which they can also utilize;
- Utilize an invitation page, with XMPP capabilities, regardless to the software
  that powers an XMPP server;
- Realize that HTTP is obsolete and should be treated as an optional publishing
  mean, because anything that HTTP offers, is already possible with XMPP, since
  a couple of decades ago.
- Extend support for Gopher and Gemini, which do not allow scripts, and,
  therefore, a server-side is essential for these ASCII type mediums.

### Special features

- Fetch vCards and photos;
- Indicate of available conferences, nodes and services;
- Retrieve number of conferences, nodes, participants, node items and services;
- Preview recent conference messages;
- View journal articles (i.e. PubSub node items that are published as Atom Over
  XMPP).

### Unintended features

- Browse services;
- Explore JID and node items.

### Other features

- Customization for specific brands (e.g. Conversations, Cheogram, monocles chat
  and yaxim);
- Dark mode;
- Dynamic background in accordance to the photo colors.
