TypeDI is a dependency injection library for TypeScript and JavaScript that manages service registration, resolution, and lifecycle via decorators and containers. It supports constructor and property injection, singleton and transient services, and multiple or scoped containers.

Use cases

• add dependency injection to a TypeScript Node.js app
• inject services with decorators instead of manual wiring
• swap fake dependencies in unit tests
• manage singleton and transient service lifecycles
• use multiple or scoped DI containers
• structure a large codebase with inversion of control

When to choose

• you use TypeScript with decorators and want decorator-based DI
• you want a lightweight, well-tested DI container for Node or browser
• you need named services, factories, or scoped containers
• you want easily testable classes with injectable dependencies

When to avoid

• you want zero-config DI without reflect-metadata and tsconfig changes
• you prefer functional composition over class-based patterns
• you need DI features like interface-only binding without tokens
• your project is plain JavaScript and needs full decorator ergonomics
