Deploy and Host Verdaccio on Railway

Verdaccio is a lightweight private npm registry. It proxies and caches the public registry, and hosts your own private packages alongside it — npm install keeps working exactly as before, but scoped packages resolve to your instance instead of npmjs.com.

About Hosting Verdaccio

A single service with a persistent volume for package storage and the user database. Point npm at the public domain and it works: published tarballs and cached upstream packages both land on the volume.

Common Use Cases

Private packages without a paid npm org: Publish @yourcompany/* to your own registry and install it anywhere with a token.
A cache in front of npmjs.com: CI installs hit your registry, which keeps a local copy — faster builds and immunity to an upstream outage or an unpublished dependency.
Package testing before release: Publish a release candidate, install it in a real project, and delete it, without burning a version number publicly.

Deployment Dependencies

Verdaccio — the registry
A Railway volume mounted at /verdaccio/storage — packages, cache and the user database
npm, yarn or pnpm on the client side

Implementation Details

Everything stateful is under the volume: storage/ for tarballs, htpasswd for accounts. That single mount is what you back up.

Configuration lives in config.yaml inside the volume, which the image writes on first boot. Registry behaviour — who may publish, which scopes are private, whether uncached upstream packages are allowed — is edited there rather than through environment variables. The defaults allow any authenticated user to publish, so the first thing to do after deploying is create your account with npm adduser --registry https:// and then tighten the packages: section.

Anonymous read access is on by default, which is what makes it usable as a transparent cache. If your package names alone are sensitive, restrict access in the config.

Storage grows with every cached upstream tarball, not only with your own publishes — a busy CI can fill a small volume faster than expected.

Why Deploy Verdaccio on Railway?

Railway is a singular platform to deploy your infrastructure stack. Railway will host your infrastructure so you don't have to deal with configuration, while allowing you to vertically and horizontally scale it.

By deploying Verdaccio on Railway, you are one step closer to supporting a complete full-stack application with minimal burden. Host your servers, databases, AI agents, and more on Railway.

Resources: a small Node process, well under 200 MB at idle, on the order of $5 a month plus volume. The cache is what grows.
