Binding new service dynamically in application

[areddy548]

we have the following scenario with REST custom connectors.

I have followed the lb4 guidelines to create REST based custom connectors, let's say i have two connectors i.e secrets and hello-world.

I also have the loopback application which has data sources, models, repositories and services for 2 integrations.

But i want to maintain a single controller which has service injection in constructor like below

@inject(ConnectorServiceBindings.CONNECTOR_SERVICE) public externalDataService: ConnectorRepositoryService,

here ConnectorRepositoryService is an interface which has contract for method called getSomething(), so i have 2 services which implements interface for calling respective connector.

So in my application.ts i have this.bind(ConnectorServiceBindings.CONNECTOR_SERVICE).toClass( SecretsService, ); this to bind the injection with respective service.

But i needed to have a condition here to select the binding like below

if (type === "secrets") { // how to pass this type during runtime
    this.bind(ConnectorServiceBindings.CONNECTOR_SERVICE).toClass(
      SecretsManagerServiceService,
    );
   } else {
    this.bind(ConnectorServiceBindings.CONNECTOR_SERVICE).toClass(
      HelloWorldService,
    );
   }

is there a way we can do this binding whenever we get new API request?????

FYI : controller has single POST end point which internally calls interface method using this.externalDataService.getData?.()!;

Question 1 : Why do you want to bind at application.ts?
Ans : In future we want to add more connectors, so doesn't want to touch the controller code every time.

We would like to dynamically load the connector at runtime base on the client request, And we could not find a proper document or an example in loopback.
It would be great if loopback support dynamic loading of connectors at runtime base on user input. Let us know if you need any more information
