This is * mainly for security reasons, as well as architectural changes in Angular 2. This means * that `index.html` can safely be processed using server-side technologies such as * providers. Bindings can thus use double-curly `{{ syntax }}` without collision from * Angular 2 component double-curly `{{ syntax }}`. * * We can use this script code: * * {@example core/ts/bootstrap/bootstrap.ts region='bootstrap'} * * When the app developer invokes `bootstrap()` with the root component `MyApp` as its * argument, Angular performs the following tasks: * * 1. It uses the component's `selector` property to locate the DOM element which needs * to be upgraded into the angular component. * 2. It creates a new child injector (from the platform injector). Optionally, you can * also override the injector configuration for an app by invoking `bootstrap` with the * `componentInjectableBindings` argument. * 3. It creates a new `Zone` and connects it to the angular application's change detection * domain instance. * 4. It creates an emulated or shadow DOM on the selected component's host element and loads the * template into it. * 5. It instantiates the specified component. * 6. Finally, Angular performs change detection to apply the initial data providers for the * application. * * * ## Bootstrapping Multiple Applications * * When working within a browser window, there are many singleton resources: cookies, title, * location, and others. Angular services that represent these resources must likewise be * shared across all Angular applications that occupy the same browser window. For this * reason, Angular creates exactly one global platform object which stores all shared * services, and each angular application injector has the platform injector as its parent. * * Each application has its own private injector as well. When there are multiple * applications on a page, Angular treats each application injector's services as private * to that application. * * ## API * * - `appComponentType`: The root component which should act as the application. This is * a reference to a `Type` which is annotated with `@Component(...)`. * - `customProviders`: An additional set of providers that can be added to the * app injector to override default injection behavior. * * Returns a `Promise` of {@link ComponentRef}. * * @experimental This api cannot be used with the offline compiler and thus is still subject to * change. */ export declare function bootstrap(appComponentType: Type, customProviders?: Array): Promise>; /** * @experimental */ export declare function bootstrapWorkerUi(workerScriptUri: string, customProviders?: Array): Promise; /** * @experimental */ export declare function bootstrapWorkerApp(appComponentType: Type, customProviders?: Array): Promise>;
