Managing dependencies across multiple repositories can be challenging, prompting many organizations to adopt Monorepos, which consolidate multiple projects into a single repository. This approach, used by companies like Facebook and Google, simplifies dependency management and allows for shared resources across projects. Lerna is a tool designed to manage Node.js-based Monorepos, facilitating tasks such as executing shared commands across projects and linking dependencies. By using Lerna, each project maintains its own package.json for dependency management, and commands can be run in parallel across different projects, enhancing efficiency. The tutorial explores setting up a Monorepo using Lerna with TypeScript and React projects, detailing the process of managing dependencies and executing tests. Additionally, it introduces Codefresh, a platform for building and deploying Monorepos using Docker, providing a streamlined workflow from development to deployment. This comprehensive guide aims to simplify Monorepo management, offering insights into tools and processes that enhance project scalability and maintainability.
