EmpackAn express-based web server framework

The framework is designed to provide an easy and lightweight development experience.

Express-Compatible

Fully compatible with existing Express middleware and ecosystem — integrate or migrate without friction.

Modular DI Architecture

Supports singleton, transient, and request-scoped lifecycles. Combined with lazy middleware resolution for high performance and clean structure.

Type-Safe Decorators

Define routes using intuitive decorators like @Controller, @Get, and @Post, with full support for parameter binding and type inference.

Built-in Mediator Support

Implements the mediator pattern to decouple controllers from application services. Controllers focus only on input/output while business logic lives in dedicated handlers.

Automatic OpenAPI Generation

Seamlessly generates complete OpenAPI specs from route and type metadata. Perfect for Swagger UI and API-first collaboration.

Lightweight

Empack minimizes boilerplate and server setup overhead. Developers can focus entirely on business logic while the framework handles routing, dependency injection, validation, and documentation out of the box.
