ExpressBackend

Defined in: src/http/backend/ExpressBackend.ts:81
Express-backed HTTP backend — drop-in alternative to the Fastify default. Intended for teams that already have an Express-based plugin ecosystem (session stores, auth, observability) they want to reuse.
express is an optional peer dependency: install it only if you use
this backend. When no app is injected, the backend imports express
dynamically and builds a fresh one.
