Example async injectable design for DI in typescript

TestAsyncDI.ts

// unfortunately typescript does not have support for static member checking in interface, if this changes create an interface for this
export default class TestAsyncInjectableService {
    private constructor(
        private injectedString: string
    ) {}

    public static async construct(injectedString: string): Promise<TestAsyncInjectableService> {
        const service = new TestAsyncInjectableService(injectedString);
        await service.doSomethingAsync();
        return service; 
    }
}

// example usage
const injectedString = "";
const injectedService = await TestAsyncInjectableService.construct(injectedString);
