Property Description
provide: any An injection token. Typically an instance of Type or InjectionToken, but can be any.
multi?: boolean When true, injector returns an array of instances. This is useful to allow multiple providers spread across many files to provide configuration information to a common token.

Usage notes


const injector = Injector.create([{provide: String, useValue: 'Hello'}]);


Multi-value example

const locale = new InjectionToken<string[]>('locale');
const injector = Injector.create([
  {provide: locale, multi: true, useValue: 'en'},
  {provide: locale, multi: true, useValue: 'sk'},

const locales: string[] = injector.get(locale);
expect(locales).toEqual(['en', 'sk']);
