Resonate HTTP Service Design

SDK version: This skill reflects @resonatehq/sdk v0.11.4 (current on npm).

Overview

Use this skill to design HTTP services where route handlers start or await durable workflows. The HTTP server is the entrypoint; durable functions do the work and coordinate via Resonate. Downstream services (like a database service) expose their own durable functions and are invoked via RPC.

Architecture Model

• HTTP service: Express/Fastify server handling routes and mapping requests to durable workflows.
• Worker service: Resonate worker group that runs durable functions for business logic.
• DB service: Separate worker group exposing durable DB functions via Resonate RPC.
• Resonate Server: Durable promise store and coordination hub.
