Function: port()

port<Port>(injector): (adapter?) => Port

Defined in: libs/act/src/ports.ts:65

The first call initializes the adapter (using the provided adapter or the injector's default). Subsequent calls return the cached singleton. Adapters are disposed in reverse registration order during disposeAndExit.

Type Parameters​

Port​

Port extends Disposable

Parameters​

injector​

Injector<Port>

Named function that creates the default adapter

Returns​

Port function: call with no args to get the singleton, or pass an adapter on the first call to override the default

(adapter?) => Port

Example​

const store = port(function store(adapter?: Store) {
  return adapter || new InMemoryStore();
});
const s = store(); // InMemoryStore
