Monorepos solve code sharing but introduce build complexity. Turborepo's caching pipeline is the missing piece that makes them scalable.
Why Monorepo?
If you have a web app, a mobile app, and a backend api, they likely share types, constants, and utilities. Keeping them in separate repos ensures they drift apart. A monorepo ensures consistency.
The Workspace Challenge
We use pnpm workspaces to link dependencies locally. However, building everything on every commit is slow. This is where Turborepo shines.
Remote Caching
Turborepo remembers what has been built. If you only change the "UI-Kit" package, Turbo knows that the "Backend" service doesn't depend on it, and skips its tests and build. When deployed to Vercel, this cache is shared across the entire team.
