✅ Ship Checklist · Day 4

From scaffold to subscriptions row.

Work top to bottom. Every box you tick saves automatically — close the tab and come back, your progress is here. The finish line is one row in your subscriptions table. Let's get you there.

Your progress

Name your build

Fill these in first — they flow into your commit

App name

Your verb (the table)

Pricing model

Your price (the number you committed to)

Wire Supabase auth

Build round 1 · ~20 min · the win = logging into your own app

Supabase project created — New project · Singapore region · ~90 sec

Keys in .env.local — URL + anon key from Settings → API (service-role stays server-side)

Magic Link enabled — Auth → Providers → Email → toggle on

Auth scaffold run (Prompt 1) — files dropped in · npm i @supabase/ssr @supabase/supabase-js

Site URL set — Auth → URL Configuration → http://localhost:3000 · dev server restarted

✅ THE WIN: logged into my own app via magic link · /app shows my email

Stuck? Wrong redirect = the Site URL trap. It catches ~40% of builders. Set it, restart, done.

Schema + RLS

3 tables max · lock every one

3 tables created — profiles · your verb · events (run Prompt 2's SQL)

RLS enabled on every table — auth.uid() = user_id

4 owner policies per table — select · insert · update · delete

Padlock check done — Database → Tables → no red unlocked padlocks

Test insert works — created a row via the SDK as the logged-in user

Wire Stripe Checkout

Build round 2 · ~20 min · TEST MODE only

TEST MODE on — orange banner visible

Product + price created — copied the price_xxx ID

3 env vars added — STRIPE_SECRET_KEY · STRIPE_PRICE_ID · NEXT_PUBLIC_URL · restarted

Checkout route built (Prompt 3) — passes customer_email + metadata.user_id

Webhook built (Prompt 4) — req.text() signature verify · upserts subscriptions

Stripe CLI forwarding — stripe listen --forward-to localhost:3000/api/webhooks/stripe · signing secret in env

Test like a founder

Prove it before you ship it

Happy path — 4242 4242 4242 4242 → Stripe shows "Succeeded"

Decline path — 4000 0000 0000 0002 → /pricing handles cancel gracefully

🎯 THE DONE BAR: a row in subscriptions with status=active after the test charge

Ship it & commit

Live URL + a public commit = today's gate

Deployed — pushed to GitHub / Vercel (or Lovable Deploy) · all prod env vars set

Prod URLs updated — Supabase Site URL + Stripe webhook endpoint → your live domain

Tested live on my phone — login + subscribe + row appears

Posted in #day-8-commits — live URL + screenshot of the subscriptions row
