What Is a Monorepo?

A monorepo is a single repository containing the source code for multiple distinct projects or packages, managed together instead of split across separate repositories.

Why it exists

• Multiple related packages (like a shared UI library and several apps that use it) benefit from being versioned, tested, and changed together
• Separate repositories for tightly related code can make coordinated changes across projects slow and error-prone

How to apply it

• Use tooling built for monorepos (like Nx, Turborepo, or npm/pnpm workspaces) to manage dependencies and run builds efficiently across packages
• A monorepo isn't automatically the right choice for genuinely unrelated projects that don't share code or need coordinated releases

FAQ

Does a monorepo mean one single deployable application?

No — a monorepo can still contain many independently deployable applications and packages; it just means their source code lives in one repository rather than several.
