Supabase Local Dev Loop

Overview

Run the full Supabase stack locally — Postgres, Auth, Storage, Realtime, Edge Functions, and Studio — using Docker and the Supabase CLI. Local development mirrors production APIs exactly, enabling offline work, fast iteration, and repeatable migration workflows. Schema changes flow through supabase db diff to generate migrations, and supabase db reset replays them cleanly.

Prerequisites

• Docker Desktop installed and running (required for all local services)
• Node.js 18+ (for npx supabase commands)
• No global install needed — all commands use npx supabase

Instructions

Step 1: Initialize Project and Start Local Stack

# Initialize Supabase in your project root
