NestJS Monorepo Examples

Example repo showing NestJS monorepo mode and conventional monorepo setups.

• conventional-monorepo uses a conventional monorepo setup
• nestjs-monorepo uses NestJS's bespoke monorepo setup

Main Differences

Feature	Conventional Monorepo	NestJS Monorepo	Description
Isolated dependency management	✅	❌	Whether each app can control its own dependencies and lock to specific version if needed. Allows apps to be upgraded one at a time instead of all at once. Dependencies for specific apps are only added to that app, not the root package.json.
Isolated build configuration	✅	❌	Whether the build conifguration can be controlled per-app. NestJS monorepo mode uses Webpack to build the apps which can cause issues with some libs.
Reduced boilerplate & configuration	❌	✅	Fewer things to manage, fewer things to go wrong.
