Angular is unable to access a service method through an observable subscription

Currently, I have a code for my service like this:

cars() {
    return 'something here';
}

Next, in order to retrieve the data using an observable from the component, I am attempting the following:

getcars() {
    this.dataService.cars().subscribe((result) => {
      console.log(result);
  });
}

Unfortunately, when trying to execute this, I'm encountering the following error message:

Error: Property 'subscribe' does not exist on type 'string'.

How would you suggest resolving this issue?

Answer №1

If you see the error message: Property 'subscribe' does not exist on type 'string', it means that you are attempting to use the subscribe() function on a string. Strings are not Observables that can be subscribed to. You should either avoid using subscribe or make sure to return an observable from the service.

To convert a value into an observable, you can utilize of.

import { of } from 'rxjs';

cars() {
  return of('something here');
}
