Deployment

Zusam is composed of a PHP server and a single-page-application. The backend uses Symfony and Sqlite, the frontend is made with Preact and ParcelJS.

Requirements:

• PHP 8.1+ (with iconv, mbstring, curl, xml, sqlite3 and imagick extensions)
• Ffmpeg 3+

Installation guides:

• Debian buster with nginx
• Debian buster with apache
• Docker

Status

The project has the goal of being really stable for the backend once 1.0 is hit. That means no database structure changes, an update system and a stable API.
The webapp can still change a lot after that point.
For now, Zusam is completely usable in a day-to-day basis but is subject to significative evolutions with upcoming updates and doesn't guarantee backwards compatibility.
I try my best to make updates as easy as possible.

Webapp compatibility

The webapp targets Firefox ESR and at most one-year old Chrome.
It should work on the latest versions of Edge and Safari but is not tested on them.
