@suaveplan/api-router-hono — concrete Hono router adapter for the @suaveplan/api plugin system. Implements the abstract Router contract from @suaveplan/api-router on top of a Hono instance, including the HonoBlueGreenSlot atomic-flip primitive and bidirectional Middleware <-> Hono MiddlewareHandler adapters. Passes runRouterConformance.

Stage-4 concrete Hono router adapter for @suaveplan/api. Implements the abstract Router contract from @suaveplan/api-router on top of a Hono Hono instance and provides the matching BlueGreenSlot implementation for hot-reload.

What it ships

• HonoRouter / createHonoRouter() — concrete Router adapter that subclasses the abstract base, mirrors every verb registration onto a private Hono app, and exposes getHonoApp() for ops integrations.
• HonoBlueGreenSlot — BlueGreenSlot impl with atomic flip, in-flight counter, AbortSignal-aware dispose(timeoutMs).
• toHonoMiddleware / fromHonoMiddleware — bidirectional bridge between the onion-model Middleware and Hono's MiddlewareHandler.
• ROUTER_HONO_CODES / RouterHonoError — stable error-code registry (ROUTER_HONO.HONO_INTERNAL_ERROR, ROUTER_HONO.INVALID_HONO_PEER).

Conformance

The package passes runRouterConformance from @suaveplan/api-router/testing — see tests/conformance.test.ts. Adding new behaviours requires re-running the harness against the adapter.

Modules

• src/adapter/adapter.md — adapter façade + factory.
• src/blue-green-slot/blue-green-slot.md — hot-reload primitive.
• src/middleware-adapter/middleware-adapter.md — middleware bridge.
• src/error-codes/error-codes.md — error registry.

Usage

import { createHonoRouter, HonoBlueGreenSlot } from "@suaveplan/api-router-hono";

const router = createHonoRouter({ plugin: "billing" });
router.get("/invoices/:id", () => null);

const slot = new HonoBlueGreenSlot("billing", () => "v1");
slot.setShadow(() => "v2");
const draining = slot.flip();
await slot.dispose(draining.slotId, { timeoutMs: 1_000 });

Dependencies

• @suaveplan/api-router — abstract contract + conformance harness.
• @suaveplan/api-types — OtelSpanLike, TenantId, Principal.
• @suaveplan/error — SuaveplanError + defineCodes.
• hono (peer ≥4.0.0) — wire-side dispatch.

Version

0.1.0 — initial Stage-4 ship. Graduates to 1.0.0 when the plugin system as a whole is declared production-ready.
