What self-hosting gives you
A self-hosted npm registry runs in infrastructure you operate. That can help when you need control over network placement, data residency, or deployment changes. It also makes your team responsible for the registry's uptime and the path from a package upload to a successful install.
Plan the whole service
- Storage and recovery: keep package metadata and tarballs durable, back them up together, and practice restoring both.
- Authentication: issue separate publish and read credentials, scope their permissions, and provide rotation and revocation.
- Transport: serve the registry over HTTPS, keep certificates current, and ensure your DNS and proxy preserve npm requests.
- Operations: monitor publish and install failures, capacity, backups, and security updates. Test behavior when storage or the authorization service is unavailable.
- Customer delivery: external customers need exact package access that you can remove when a relationship ends.
When a managed registry fits
If your main goal is private package delivery rather than operating registry infrastructure, a managed service can take on the hosting work. PrivateNPM.com is a hosted private npm registry with shared scopes, private registry namespaces, custom domains, publisher keys, and read-only download keys. A custom registry domain changes the address customers use; it does not make the deployment self-hosted.
Compare the total operating work alongside subscription cost: backups, upgrades, incident response, and the time required to build customer access rules. See plans and limits or start with the private registry basics.
