Postgres Realtime location sharing with MapLibre
Using the power of Postgres and Supabase Realtime[0] we can easily draw our live location onto the Map using MapLibre GL JS. In this example, we're using the live location shared from a Telegram bot to a Supabase Edge function to insert the location data into the database. Subsequently Supabase Realtime is broadcasting the location updates to any connected web JavaScript client via WebSockets.
