Notes from building next-supabase-saas.
A step-by-step guide to wiring Supabase (database + auth) into a Next.js App Router project. Covers the lib/supabase client helpers, environment variables, and RLS basics — with a real-world example from my vocal practice app.
I built two SaaS projects with Next.js + Supabase + R2 + Modal. Both times, the hardest part wasn't the business logic — it was the setup.
