Lerna

Lerna is a tool for managing JavaScript projects with multiple packages, known as monorepos. It optimizes workflows by handling tasks like linking dependencies, versioning, and publishing across packages in a single repository. It is commonly used with npm or Yarn to streamline development in large-scale applications.

Also known as: LernaJS, Lerna tool, Lerna monorepo, Lerna CLI, Lerna package manager

Why learn Lerna?

Developers should use Lerna when working on projects with interdependent packages, such as libraries, frameworks, or microservices, to reduce complexity and improve consistency. It is particularly valuable for teams needing coordinated releases, shared dependencies, and efficient testing across multiple packages, as seen in projects like Babel or React.
