How to initialize all services without getting?

[gomin1d]

My program:

import "reflect-metadata";
import { Container } from "inversify";
import { DbService } from "@/service/db/db-service";
import { ExpressService } from "@/service/express/express-service";
import { SignUpService } from "@/service/signup/sign-up-service";
import { ProfileService } from "@/service/profile/profile-service";

let container = new Container({ defaultScope: "Singleton" });

container.bind(DbService).toSelf();
container.bind(ExpressService).toSelf();
container.bind(SignUpService).toSelf();
container.bind(ProfileService).toSelf();

But these services are not initialized until I get them via container.get*. How do I cause the initialization of ALL services?
