Verdaccio In-Memory Authentication Plugin

verdaccio-auth-memory is an authentication plugin for Verdaccio, a lightweight private npm proxy registry. It is designed to store user credentials and session data exclusively in runtime memory. This crucial design choice means that all user information, including registered users and active sessions, will be lost upon any restart of the Verdaccio server. The current stable version is 10.3.2. As part of the Verdaccio monorepo, it follows a coordinated release schedule with the main Verdaccio project and other associated plugins. Its primary differentiator is its ephemeral nature, making it explicitly unsuitable for production environments that require persistent user management. Instead, it is primarily intended for development, testing (e.g., unit tests, CI environments), or transient demonstration purposes where data loss on restart is acceptable and even desired for a clean state.
