[Feature Request] Support for ZenStackMiddleware in NestJS Fastify Projects

[LeUKi]

Is your feature request related to a problem? Please describe. Yes. ZenStackMiddleware currently only supports Express.js, but I am using NestJS with Fastify due to its superior performance benefits. The existing @zenstackhq/server/express middleware cannot be directly integrated into a NestJS Fastify project. Attempts to adapt parameters or simulate Express behavior (e.g., modifying MiddlewareOptions) have failed, likely due to incompatible request/response object structures or middleware execution flows.

Describe the solution you'd like I request support for ZenStackMiddleware in NestJS Fastify projects .

Describe alternatives you've considered Manual adapter layer : I attempted to wrap the Express middleware for Fastify by adapting req/res objects and parameters, but this failed due to deeper incompatibilities. Manual solutions are error-prone and require ongoing maintenance.

Hi @LeUKi , the @zenstackhq/server package actually has a fastify adapter

Have you looked at it? I've never tried using it with NestJS though.
