 ### Completed
 
-- [x] **Next.js Adapter** — App Router, Auth/GraphQL/Meta/Data/Storage handlers (9/10)
+- [x] **Next.js Adapter** — App Router, Auth/GraphQL/Meta/Data/Storage handlers (10/10)
 - [x] **NestJS Adapter** — Full DI module, Express/Fastify support (10/10)
 - [x] **Hono Server Plugin** — Production HTTP server with static file serving
-
-### Remaining
-
-- [ ] **Hono Adapter** — Currently a stub (middleware only). Needs full route dispatchers for Auth/GraphQL/Meta/Data/Storage matching Next.js/NestJS completeness
-- [ ] **Next.js Server Actions** — Support for React Server Actions pattern
-- [ ] **Express Adapter** — Standalone Express integration (currently via NestJS only)
-- [ ] **Fastify Adapter** — Standalone Fastify integration (currently via NestJS only)
-- [ ] **SvelteKit Adapter** — Community request
-- [ ] **Nuxt Adapter** — Community request
+- [x] **Hono Adapter** — Full route dispatchers for Auth/GraphQL/Meta/Data/Storage with createHonoApp
+- [x] **Next.js Server Actions** — createServerActions with query/getById/create/update/remove/getMetadata
+- [x] **Express Adapter** — Standalone Express v5 router with all ObjectStack routes
+- [x] **Fastify Adapter** — Fastify plugin with full route dispatchers
+- [x] **SvelteKit Adapter** — Web-standard Request/Response based handler for SvelteKit routes
+- [x] **Nuxt Adapter** — h3 router integration for Nuxt server routes

+- Middleware mode for attaching kernel to requests
+
+## Usage
+
+```typescript
+import express from 'express';
+import { createExpressRouter } from '@objectstack/express';
+
+const app = express();
+app.use(express.json());
+app.use('/api', createExpressRouter({ kernel }));
+
+app.listen(3000);
