this is super lightweight 5kb typescript

import { Inject } from 'inject.min';

class Example {
  value: string;

  constructor(props?: { param: string }) {
    this.value = props?.param || 'example';
  }
}

class Example2 extends Example {
  constructor(param: string) {
    super({ param });
  }
}

class Test {
  @Inject(Example) example!: Example;
  @Inject(Example2, 'example2') example2!: Example2;
  @Inject(Example, { param: 'example3' }) example3!: Example;

  constructor() {
    console.log(this.example.value); // example
    console.log(this.example2.value); // example2
    console.log(this.example3.value); // example3
  }
}

class Test2 {
  @Inject(Example) example!: Example;
  @Inject(Example2, 'different') example2!: Example2;
  @Inject(Example, { param: 'example3' }) example3!: Example;

  constructor() {

}

class Test3 extends Test {}

const test = new Test(); // example, example2, example3
const test2 = new Test2(); // example, different, example3
const test3 = new Test3(); // example, example2, example3

console.log(test.example === test2.example); // true
console.log(test.example2 === test2.example2); // false
console.log(test.example2 === test3.example2); // true
