A build system and monorepo management tool for the web ecosystem, written in Rust.
moon is a Rust-based build system and repository management tool for web projects, including monorepos, where multiple related packages live in one repository. It coordinates projects and tasks, standardizes language and package-manager versions, and reduces duplicated scripts. The catalogue skills and instructions support working with moon-managed repositories.
