The text explores various tools for managing monorepos, which are repositories that contain multiple projects, particularly for JavaScript and TypeScript applications. It highlights the complexities of monorepos, such as managing dependencies and improving scalability, and compares five popular tools: Bazel, Gradle, Lage, Lerna, and Rush, each with their unique features, benefits, and challenges. Bazel is noted for its speed and scalability but requires BUILD files and has a steep learning curve. Gradle is praised for its fast build times and integration with major IDEs, although it lacks support for running commands on multiple machines. Lage, developed by Microsoft, offers ease of adoption and efficient CPU usage, but it only works with npm. Lerna is user-friendly and supports multiple package management but is not actively maintained. Rush, also from Microsoft, is designed for large teams and repositories but lacks multi-language support. The article concludes that Earthly, an open-source CI/CD framework, can be used alongside these tools to enhance build processes with containerized and parallel task execution.
