Internal registries like Verdaccio, Artifactory, and GitHub Packages are essential for managing a monorepo efficiently and avoiding dependency chaos.
Verdaccio is a lightweight option suitable for small teams, while Artifactory offers enterprise-grade features but comes at a higher cost.
GitHub Packages is integrated with GitHub and ideal for teams already using GitHub Actions, but storage limits may be a concern for private packages.
Key steps for building an npm empire include choosing the right registry, publishing packages, enforcing version control, automating processes, and prioritizing security and documentation.
