JavaScript Framework Integrations: - Express.js middleware with router and request-level facade - Fastify plugin with decorators and route helpers - NestJS module with forRoot/forRootAsync and decorators - Hono middleware for edge environments Rust Framework Integrations (feature-gated): - Axum integration with Tower layer and extractors - Actix-web integration with middleware and extractors Deployment Tools: - Docker images (multi-stage builds for JS and Rust) - docker-compose.yml for single node deployment - docker-compose.cluster.yml for multi-node cluster - Kubernetes Helm chart with HPA, PVC, and ConfigMap support CLI Enhancements: - Queue management commands (create, delete, list, info, purge) - Message operations (send, receive, peek, ack, reject) - Cluster management (status, join, leave) - Statistics and health check commands Closes #28 Co-Authored-By: Claude Opus 4.5 --- docker-compose.cluster.yml | 136 +++ docker-compose.yml | 56 ++ docker/Dockerfile
