    What is this?

    Private npm registry and web for Enterprise, base on koa, MySQL and Simple Store Service.

    Our goal is to provide a low cost maintenance and easy to use solution for private npm.

    What can you do with

    • Build a private npm for your own enterprise. (alibaba is using now)
    • Build a mirror NPM. (we use it to build a mirror in China:
    • Build a completely independent NPM registry to store whatever you like.


    • Support "scoped" packages: npm/npm#5239
    • Support CORS
    • Simple to deploy: only need mysql and a simple store system. You can get the source code through npm or git.
    • Low cost and easy maintenance: package.json info store in MySQL, MariaDB, SQLite or PostgreSQL databases, tarball(tgz file) store in CDN or other store systems.
    • Automatic synchronization: automatic synchronization from any registry specified, support two sync modes:
      • Sync all modules from a specified registry, like npm registry.
      • Only sync the modules that exists in your own registry.
    • Manual synchronization: automatic synchronization may has little delay, but you can syn immediately by manually.
    • Customized client: we provide a client cnpm to extend npm with more features(sync command, gzip support). And it easy to wrap for your own registry which build with
    • Compatible with NPM client: you can use the origin NPM client with, only need to change the registry in config. Even include manual synchronization (through install command).
    • Version badge: base on cnpm-badge
    • Support http_proxy: if you're behind firewall, need to request through http proxy

    PROTIP Be sure to read Migrating from 1.x to 2.x as well as New features in 2.x.
