JavaScript Monorepos with Lerna

Lerna is a monorepo manager for JavaScript projects that facilitates code sharing by allowing large codebases to be split into independently deployable packages, managing the entire release process, and integrating with tools like npm and Yarn. It supports fixed and independent versioning schemes, enabling developers to choose between maintaining a uniform version across all packages or versioning them separately. Lerna is utilized by notable projects such as Babel, Jest, and AngularJS, and supports CI/CD pipeline integration with tools like Semaphore for automating testing and publishing workflows. By leveraging Lerna's capabilities, developers can streamline development processes, improve package management, and enhance collaboration in monorepos, making it an essential tool for JavaScript developers looking to efficiently manage and publish their packages on NPM.
