Keycloak Node.js Connect Adapter

The `keycloak-connect` package provides a Node.js Connect-friendly middleware for integrating applications with Keycloak, an open-source identity and access management solution. It simplifies implementing authentication and authorization using Keycloak for modern applications and services. The current stable version is 26.1.1. However, this package is officially deprecated by the Keycloak project, with plans for removal in the future, and users are advised to seek alternative integration strategies. Key differentiators included its direct integration with the Connect/Express ecosystem, providing session management and protection for routes, but its deprecation signals a shift away from this specific adapter approach in favor of more generic OIDC client libraries. While it offered a streamlined setup for Keycloak, its maintenance and future are uncertain due to the deprecation notice.
