Supabase Realtime

This handles WebSocket connections to Supabase Realtime using websocat, letting you subscribe to database changes, broadcast messages between clients, and track presence in channels. You get practical bash scripts for listening to INSERT, UPDATE, and DELETE events on specific tables, filtering by row conditions, and processing changes with custom handlers. The examples show how to build continuous listeners that pipe events through jq for processing, which is useful for triggering workflows or notifications when your database changes. It's honestly a bit clunky compared to using the JavaScript client, but if you're working in bash or need to integrate realtime features into shell scripts, the patterns here give you what you need to subscribe to table events and handle the WebSocket protocol directly.
