Creating a Modular Monorepo, Frontend Meets Backend
· 2 min read
Overview
Once the schema and core features were taking shape, I needed a scalable way to manage both frontend and backend in a single codebase. My goals were:
- Reduce context switching
- Share types between API and UI
- Optimize for developer speed and clarity
I chose a monorepo setup using PNPM workspaces. This let me keep backend (NestJS), frontend (Next.js), and shared types/utilities in separate packages—but in one unified repository.
Monorepo Structure
Here's the high-level layout I landed on:
apps/
├── frontend/ # Next.js app (SSR, client, UI logic)
└── backend/ # NestJS API with Prisma
packages/
├── shared/ # Common interfaces, enums, helper functions
└── config/ # Shared tsconfig, eslint, env loaders
prisma/ # Central schema, migrations
scripts/ # Utility scripts for seeds, exports
