Section

Auth in an Afternoon

Supabase Auth with email OTP + Google. Do not build your own.

Section

Roles and RLS

Roles table, RLS policies, a has_role function. Ship every project with these on day one.

Section

Stripe in One Sitting

Payment Links for MVPs. Checkout Sessions when you need metadata. Webhooks for provisioning.

Section

Transactional Emails

Resend + React Email. Signup, receipt, password reset. That is enough.

A single templated page is fine. Existence matters more than perfection.
