Aube vs npminstall

Aube is an open-source Node.js package manager written in Rust for Linux, macOS, and Windows. Its aubr command checks dependencies before running a project script and installs those that are missing or stale. Aube reads and writes supported pnpm, npm, Yarn, and Bun lockfiles, while its content-addressable store shares package directory trees across projects and worktrees. For one-off tools, aubx uses a local binary when available or installs the tool in a throwaway project. Workspaces, filters, and catalogs can be configured through pnpm-workspace.yaml or aube-workspace.yaml, and commands can use a project-pinned Node version. Security checks consider publishing evidence, release age, and known malicious packages during version selection. Dependency lifecycle scripts need project approval or built-in trust, with explicit denials taking precedence. Optional integrity verification checks fetched registry tarballs against recorded values. Installation options include mise, Homebrew, npm, Cargo, distribution packages, and source builds. Aube also provides embedding integrations for Rust, Node-API hosts, and C ABI consumers, plus a GitHub Action. Yarn Plug'n'Play projects are not supported and require a node_modules linker.
