Monorepo
A monorepo is a software development strategy where multiple projects or components are stored in a single version-controlled repository, rather than in separate repositories. It centralizes code management, dependencies, and tooling across an organization or large codebase, enabling shared libraries, consistent workflows, and easier cross-project collaboration. This approach is commonly used by large tech companies like Google, Facebook, and Microsoft to manage complex systems.
Developers should use a monorepo when working on large-scale applications with interdependent components, such as microservices, shared libraries, or full-stack projects, to simplify dependency management, enforce code consistency, and streamline CI/CD pipelines. It is particularly beneficial in organizations where teams need to coordinate changes across multiple projects, as it reduces integration overhead and facilitates atomic commits that span different parts of the codebase.
