Monorepo
A monorepo is a software development strategy where multiple projects or packages are stored in a single version-controlled repository, rather than in separate repositories. It centralizes code management, enabling shared dependencies, unified builds, and streamlined collaboration across teams. This approach is commonly used in large-scale applications to maintain consistency and reduce integration complexity.
Developers should use monorepos when working on interconnected projects that share libraries, configurations, or tooling, such as in microservices architectures or multi-package JavaScript applications. It simplifies dependency management, enforces code standards, and facilitates cross-project refactoring, making it ideal for organizations like Google or Facebook that manage vast codebases. However, it may add overhead for smaller teams or unrelated projects.
