hapi‑saml2 is a Hapi.js plugin that adds SAML 2.0 single‑sign‑on (and optional single‑logout) capabilities to a Hapi server by wrapping the node‑saml library. It exposes standard SAML endpoints (metadata, login, logout, callback) and lets developers hook into the login/logout flow via configurable callbacks, making it suited for Node developers needing SAML authentication in Hapi applications.
