Asena

A high-performance IoC web framework for Bun runtime, bringing Spring Boot's automatic component discovery and field-based dependency injection to TypeScript.

Philosophy

Spring Boot and Quarkus have established proven patterns for enterprise application development, but developers transitioning to TypeScript often find themselves reimplementing familiar concepts or adapting to unfamiliar architectures. AsenaJS addresses this gap by bringing automatic component discovery, field-based dependency injection to the Bun ecosystem.

The framework eliminates boilerplate through automatic scanning of decorator-annotated classes, removing the need for explicit module declarations or manual wiring. Components marked with @Controller, @Service, or @Repository (via asena-drizzle package) are discovered and registered automatically, allowing developers to focus on business logic rather than configuration. This approach, combined with Bun's native performance characteristics, delivers both the familiar developer experience of Spring Boot and the speed expected from modern JavaScript runtimes.

AsenaJS is designed to make developers familiar with Spring Boot and Quarkus feel at home in the TypeScript ecosystem. As the framework evolves, we remain committed to this philosophy—bringing more proven patterns from the Java world while maintaining the performance advantages that Bun provides and flexiblity of Typescript.
