Deep-dive tutorials, practical product notes, and real-world engineering advice for developers building modern web apps.
Row Level Security finally clicked for me after one scary near-miss. Real policies you can copy — todos, blogs, teams, and admin roles.
Production errors don't come with stack traces. Here's my exact debugging workflow for Next.js — digests, logs, Sentry, and hydration bugs.
NextAuth kept fighting me, so I built auth with Supabase and @supabase/ssr instead. Cookies, middleware, protected routes — the full setup.
After three painful refactors, this is the exact Next.js folder structure I now use for every large project. Copy it and save yourself the mess.
My client didn't want a dashboard, he wanted Google Sheets. Here's the free setup I use to sync Supabase data to Sheets automatically.
Ten real Supabase errors from my production apps — RLS violations, JWT expiry, connection limits — with the exact fixes that worked.
I built a complete inventory system for a client with Next.js and Supabase. The schema, the race-condition mistake, and what I'd do differently.
Most "build a SaaS" tutorials either hand-wave the hard parts or drown you in setup. This is the middle path: the exact, sensible stack for shipping a Next.js SaaS in 2026 — auth, data, billing, and deploy — without over-engineering it.
A while back I was manually copying leads from a Google Sheet into an email tool, one row at a time, three times a day. It was the kind of task that takes ten minutes but eats your whole afternoon because you keep putting it off. I finally got sick of it and signed up for Zapier. Great — problem solved. Until the free tier ran out, my "zaps" started failing quietly, and the bill for doing anything remotely complex made me wince.
