Epic: Make Zitadel Easier to Adopt in Backend #39
Description
Summary: Deliver the core zitadel-backend-auth library and official integration examples for key Node.js backend frameworks, to simplify Zitadel adoption.
The Node.js backend ecosystem is a fragmented landscape of frameworks like Express.js, NestJS, Fastify, Hapi, and Koa. Users often integrate authentication using abstraction libraries like Passport.js. Our goal is to build a comprehensive zitadel-backend-auth library, potentially piggybacking on existing patterns, to significantly simplify the implementation of Zitadel authentication directly onto these backend frameworks.
