Supabase Realtime presence tracking works by monitoring active users within shared channels to enable collaborative app features. You can use it to sync user states across clients and build live monitoring dashboards without polling the database.

Yes, you can broadcast messages to channel groups using Supabase Realtime. This skill demonstrates how to send and receive broadcast events, allowing you to build real-time messaging and notification systems across multiple connected clients.

Prerequisites for setting up Supabase Realtime subscriptions include a configured Supabase project and an understanding of WebSocket connections. This skill covers required tooling, subscription payloads, and example workflows to implement end-to-end real-time patterns.

The best way to manage multiple Supabase Realtime channels for live monitoring is to configure distinct subscriptions for each table and event type. This skill provides example workflows demonstrating how to handle presence events, broadcasts, and database changes simultaneously.

A Supabase Realtime subscription may stop working across multiple tables if channel configurations or event types are incorrectly set up. This skill helps troubleshoot by providing correct message formats, subscription payloads, and practical patterns for real-time data streams.
