monoship is a CLI tool and library that automates publishing npm workspace packages to any registry (npmjs, GitHub Packages, etc.). It detects which workspace packages have new versions, resolves workspace protocols, handles version conflicts, and supports both classic token authentication and token‑less OIDC trusted publishing—making it ideal for CI/CD pipelines and GitHub Actions. Target users are JavaScript/TypeScript monorepo maintainers who want reliable, automated publishing of their packages.
