Monorepo` is a single `git repository` that holds the source code for projects, contrasting the poly-repo strategy where each project exists in a separate `git repository`. A well-organized monorepo is more than just colocating different projects; it's about bringing them together to foster communication, reuse, and shorten the feedback loop between collaborating teams. Monorepos offer benefits such as code reusability, consistency, simplified scaffolding, faster feedback loops, enhanced collaboration, security, unified versioning, and better integration with build systems like Nx. However, they also come with challenges that require planning, defining boundaries, and setting up CI efficiently. Netlify has introduced an enhanced monorepo experience to simplify the deployment phase for enterprises, offering advanced heuristics to detect settings, provide site pickers, and streamline local development with the CLI.
