Tripleta

Overview

A Splitwise-style group expense-splitting app built on Next.js App Router, Prisma, and MySQL, with NextAuth (Credentials + Google).

Tripleta started as a Lovable + Supabase prototype. Moving to a self-hosted Next.js, MySQL, and Prisma stack meant Postgres Row-Level Security no longer existed to lean on — so authorization had to become an explicit, testable application layer instead of a database-level guarantee.

Highlights

• Deliberate migration off Lovable + Supabase to a self-hosted Next.js + MySQL + Prisma stack.
• Replaced Postgres RLS with an explicit authorization layer (server/dal.ts + server/authz.ts) — access rules live in application code, not database policies.
• NextAuth with both Credentials and Google sign-in.
• Tailwind CSS + shadcn/ui for the interface, Zod for end-to-end input validation.
