di allows you to autowire classes into other clases by declaring them as services.
Take this example:
di.ts
import 'reflect-metadata'
export const { di, Service, inject, injectAll } = createServiceLocator();network-service.ts
import {Service} from './di';
@Service()
export class NetworkService() {
public connect() {}
}user-service.ts
import {Service} from './di';
@Service()
export class UserService() {
public UserService(private networkService: NetworkService) {
}
private doStuff() {
this.networkService.connect();
}
}index.ts
const userService = di.get(UserService); // resolves all dependencies
userService.doStuff();Other features include tagging services and injecting all services tagged with a specific tag. Also custom service injections can be propsed.
