Interface ExistingProvider<Value>

An optional name to qualify this provider. If specified, the token must be resolved using the same name.

Example:

export class ExtensionContext {
  // Decorator-based injection
  constructor(@Inject(ISecretStorage) @Named("persistent") secretStorage: SecretStorage) {}

  // Function-based injection
  constructor(secretStorage = inject(ISecretStorage, "persistent")) {}
}
Copy

The existing token to alias, with an optional name qualifier.

Example:

container.register(ISecretStorage, {
  useExisting: PersistentSecretStorage,
});

// Or in case we need to alias a name-qualified token
container.register(ISecretStorage, {
  useExisting: [PersistentSecretStorage, "fileSystem"],
});
