_Elegant Dependency Injection in JavaScript and TypeScript._

- `Optional`, `SkipSelf`, `Self`, `Many` support; just like Angular!
- Purely functional injection without any runtime reflection.
- Strict integration with TypeScript.
- Easy testability with the Container-based API.
- Rigorously tested API (nearly 100% coverage!)
- **🔥 10 kB bundle size.** (no dependencies!)

~~(The only thing it can't do is make coffee.)~~

_Dependency Injection in 23 lines:_

```ts
import { Service, Container } from '@typed-inject/injector';

// Make a service that logs a message to the console.
@Service([])
class LogService {
  log(message: string) {
    console.log(message);
  }
}

// Then, use our logging service in our root service,
// which will log "hello world!" to the console.
@Service([LogService])
class RootService {
  // Store the instance of the logger inside the class.
  constructor(private logger: LogService) {}
  run() {
    this.logger.log('hello world!');
  }
}

// Now, run our service!
Container.get(RootService).run();
```
