AxilJS — Backend Ecosystem
A modular, next-generation JavaScript/TypeScript backend ecosystem for production-grade apps — one coherent toolkit from HTTP and routing to ORM, auth, real-time, queues, AI and observability.
The problem
Backend teams keep re-implementing the same infrastructure — HTTP handling, routing, auth, validation, security, data access, queues, events, real-time, testing and observability — differently on every project.
Architecture
- 01Package-based architecture with npm workspaces and CLI tooling
- 02Unified HTTP, routing, ORM, auth, validation, WebSockets, SSE, queues and AI modules
- 03Built for both low-latency monoliths and microservices
- 04Developer experience, reliability and enterprise adoption as first principles

What I owned
- 01Architected the overall ecosystem and its package boundaries
- 02Designed the HTTP and routing infrastructure
- 03Implemented authentication, security, validation and ORM / data access
- 04Designed event and queue infrastructure; added WebSockets and SSE
- 05Integrated AI / LLM capabilities and built the CLI tooling
- 06Focused on testing, observability, extensibility and developer experience
Outcome
A reusable backend ecosystem covering infrastructure from HTTP and routing through data, security, events, queues, real-time, AI, testing, observability and CLI tooling.
