monorepos are regaining a lot of popularity, they cut complexity and costs.
monorepo is a single version control repository that houses the code for multiple, often independent projects.

• Projects within a monorepo can be entirely separate applications, services (like microservices), or shared libraries.
• They might even use different programming languages or frameworks.
• The key is that all the code lives in one repository, making it easier to share code, manage dependencies, and perform atomic commits across related projects.

Turborepo (by Vercel) is a build system
you can break down a mono repo down into small focused package and you can cache each build. saving a lot of costs in CI compute.
