Verdaccio Hosting

How Verdaccio works

Verdaccio implements an npm-compatible registry that can accept private package publications and proxy requests to an upstream registry. When a requested public package is not already cached, Verdaccio can fetch it from the configured uplink and retain a local copy. Package managers then use one registry address for both internal packages and permitted upstream dependencies.

The registry stores package metadata, archives, users, and configuration through its selected storage and authentication plug-ins. The standard setup uses local application storage, while optional plug-ins can connect other backends. Those external services are not part of the hosted package and require separate compatibility, credentials, and administration.

Key Verdaccio features

Access rules can distinguish package scopes and control who may read, publish, or proxy packages. The web interface helps users inspect available packages and versions, while npm-compatible clients handle login, installation, publication, and deprecation commands. Teams should test their chosen npm, Yarn, pnpm, Bun, or other client version against current Verdaccio documentation.

A private registry does not review source code, approve licences, scan every package, or guarantee that cached upstream content is safe. Administrators remain responsible for account policy, package ownership, namespace rules, retention, dependency controls, and the consequences of allowing proxy access to external registries.

Verdaccio vs npm private packages

Verdaccio is a self-hosted registry and proxy whose package data and access policy remain with the operator. npm offers private packages through npm accounts and organisations on its hosted registry, with billing and permissions handled through the provider’s service rather than a customer-operated registry instance.

npm private packages may suit teams that prefer the public npm ecosystem, vendor-hosted administration, and provider-operated availability. Verdaccio is a better fit when an organisation needs an internal endpoint, local caching, custom uplinks, or package policies that it manages directly. Neither choice removes the need for dependency review and credential security.

Who uses Verdaccio

Development teams publish internal libraries, build pipelines install private components, classrooms distribute course packages, and remote offices cache commonly used public dependencies closer to their users. A registry can also isolate experimental packages from public namespaces while preserving familiar package-manager commands.

Verdaccio is not a complete software-supply-chain security platform. Organisations may still need source control, code review, signing, vulnerability scanning, licence checks, provenance controls, build isolation, secret management, and incident procedures around their package workflow.

Self-hosting Verdaccio: requirements and cost

Verdaccio demand grows with package count, archive size, cached dependencies, publication frequency, concurrent installs, metadata requests, and proxy traffic. The catalogue records PostgreSQL and MariaDB as Not required; the default registry data is persisted in application storage and must be protected together with configuration and authentication state.

On AvaHost, Verdaccio uses Plan 1 at €2. The hosted Verdaccio package includes one-click deployment, a custom domain with automated HTTPS, automatic application updates, and scheduled backups. The hosted service supplies the registry application, not npm accounts, external storage backends, vulnerability feeds, code-signing services, build workers, or package approval. Configure package access before sharing the endpoint, use scoped credentials, and test restores and client behaviour before depending on the registry for critical builds.
