Supabase released @supabase/middleware, a composable, type-safe middleware library for Web Fetch handlers. It allows developers to define per-request logic once and run it on any runtime that supports fetch, including frameworks like Hono, H3, Elysia, NestJS, and TanStack Start via a short bridge file. The library is MIT-licensed and free.

## Evidence

Verbatim from https://supabase.com/blog/supabase-middleware:

> You can now write per-request logic once and run it on any runtime that supports fetch. The same middleware also works inside frameworks like Hono, H3, Elysia, NestJS, and TanStack Start.
