Express OpenID Connect Middleware

express-openid-connect is an Express.js middleware designed to integrate OpenID Connect (OIDC) authentication into web applications, streamlining user login and session management. Currently at version 2.20.2, the library is actively maintained with a regular release cadence, frequently addressing bug fixes and introducing minor features. It abstracts away much of the complexity of OIDC flows, particularly when used with Auth0 as an identity provider, by handling authentication, logout, and session management automatically. Key differentiators include its focus on Express applications, deep integration capabilities with Auth0, and providing sensible defaults to secure web applications, while also offering extensive configuration options for advanced use cases. It ships with TypeScript types, enhancing developer experience for type-safe applications.
