Why HeliosJS?

Everything you need to build modern Node.js applications

🎯

Decorator-First

Write clean, declarative code using TypeScript decorators. Controllers, routes, and middleware are defined with intuitive decorators.

🚀

TypeScript Native

Built with TypeScript from the ground up. Full type safety, intelligent autocomplete, and excellent IDE support.

🔌

Modular Architecture

Use only what you need. Core package provides the foundation, while HTTP, WebSocket, and middleware packages add functionality.

⚡

High Performance

Built on Node.js core with minimal overhead. Fast routing, efficient middleware execution, and optimized for production workloads.

🔧

Extensible

Create custom plugins, middleware, and decorators. Extend the framework to fit your needs.
