Passport Keycloak Bearer Strategy

Passport-Keycloak-Bearer is an HTTP Bearer authentication strategy designed for Passport.js, enabling Node.js applications to authenticate requests against a Keycloak identity provider using OAuth 2.0 bearer tokens. This package, currently at version 2.4.1, integrates seamlessly with Connect-style middleware frameworks like Express.js. It focuses on extracting, validating, and propagating JWT claims from access tokens to a `verify` callback, allowing developers to process user information and attach it to `req.user`. While there isn't an explicit release cadence mentioned, the versioning suggests ongoing maintenance. Its key differentiator is the direct integration with Keycloak's token validation, simplifying the setup for Keycloak-backed applications compared to generic JWT strategies that require manual configuration of Keycloak's public keys and issuer metadata.
