Ember object ownership (getOwner, service injections, etc.)

:warning: Importing getOwner from discourse-common/lib/get-owner is deprecated.

To access e.g. services there a couple of methods at your disposal.

• In components/controllers/routes you should use service injections

  jsCopy

  import { service } from "@ember/service";
  
  export default class Something extends Component {
    @service router;
  

• In cases where a service can be unavailable (i.e. it comes from an optional plugin) there's a optionalService injection

  jsCopy

  import optionalService from "discourse/lib/optional-service";
  
  export default class Something extends Component {
    @optionalService categoryBannerPresence;
  

• In API initializers you have the access to api.container

  jsCopy

  apiInitializer((api) => {
    const router = api.container.lookup("service:router");
  

• And for a direct replacement of an existing code you can use

  jsCopy

  import { getOwner } from "@ember/application";
  

• …or if you still need the fallback shim (in a non-component/controller/route/widget context) use

  jsCopy

  import { getOwnerWithFallback } from "discourse-common/lib/get-owner";
