Supabase Edge Functions run on Deno Deploy and are far more capable than simple REST handlers. This guide covers three advanced patterns every indie developer should know: streaming responses (for LLM integrations), WebSocket upgrades (for real-time features), and background jobs using EdgeRuntime.waitUntil. The most common use case is streaming LLM output without blocking the client. // supabase/
Supabase Realtime streams PostgreSQL changes to clients over WebSocket. Combine it with Flutter and you can ship live notifications, "who's online" indicators, and collaborative editing in dozens of lines of code. This guide covers all three channel types — Postgres Changes, Presence, and Broadcast — with production-ready examples. Type Use Case Data Source Postgres Changes React to INSERT/
If you've been building with Supabase, you know their Storage API is fantastic for web apps. But sometimes, you just need your files on your local machine—whether for a manual backup, bulk editing, or migrating data. While you could write a script using the Supabase SDK, there is a much faster, "no-code" way to manage your files like a Pro: Cyberduck. Note: Cyberduck is an official Supabase partne
