class Foo {
    hello() {
        return "world"
    }
}

@injectable class Bar {
    @inject(Foo) foo: Foo

        console.log(`fizz${baz} from ${this.foo.hello()}`)
    }
}

const bar = new Bar("buzz")

API

@injectable

Decorator that makes a class injectable and ensures it works properly

Caveats

• Transforms class into a proxy

@inject(target, ...args)

@inject.singleton(target, ...args)

replaceService(dependency, newDependency)

Overrides the dependency as to point to a different one

@injectable class A {
    @inject(B) b: B;
}

const a0 = new A();
replaceService(B, C);
const a1 = new A();

expect(a0.b instanceof B).toBe(true);
