LeanTrack

01 / problem

Tracking nutrition without friction

Staying on track means seeing calories and macros against your goals every day, with as little effort as possible when logging a meal.

02 / solution

Goals, products and a daily diary

Users register and sign in, set nutrition goals, manage a list of products and add food diary entries. The API exposes auth, products, diary and goals endpoints, and the frontend is organised by the same features.

03 / architecture

How it works

A pnpm monorepo with a Fastify + TypeORM backend (feature modules for auth, diary, products and goals; config for environment, JWT and database; migrations) and a Vue 3 + Vite frontend split into features, shared code and the router. PostgreSQL runs in Docker Compose. Both apps use TypeScript strict mode, ESLint, Prettier and Vitest.

What I learned

• Mirroring the backend modules in frontend features keeps each feature easy to find on both sides.
• A PRD, a tech spec and user-flow diagrams sit in docs/ next to the code, so the intent behind each module stays on record.
