PlatformRef

interface

The Angular platform is the entry point for Angular on a web page. Each page has exactly one platform, and services (such as reflection) which are common to every Angular application running on the page are bound in its scope.

interface PlatformRef {
  injector: Injector
  destroyed
  bootstrapModuleFactory<M>(moduleFactory: NgModuleFactory<M>, options?: BootstrapOptions): Promise<NgModuleRef<M>>
  bootstrapModule<M>(moduleType: Type<M>, compilerOptions: (CompilerOptions & BootstrapOptions) | (CompilerOptions & BootstrapOptions)[] = []): Promise<NgModuleRef<M>>
  onDestroy(callback: () => void): void
  destroy()
}

Description

A page's platform is initialized implicitly when a platform is created via a platform factory (e.g. platformBrowser), or explicitly by calling the createPlatform function.

Properties

injector: Injector

Read-Only Retrieve the platform Injector, which is the parent injector for every Angular application on the page and provides singleton providers.

destroyed Read-Only

Methods

Creates an instance of an @NgModule for the given platform for offline compilation.

bootstrapModuleFactory<M>(moduleFactory: NgModuleFactory<M>, options?: BootstrapOptions): Promise<NgModuleRef<M>>

Parameters
moduleFactory NgModuleFactory
options BootstrapOptions Optional. Default is undefined.
Returns

Promise<NgModuleRef<M>>


Usage Notes

Simple Example
my_module.ts:

@NgModule({
  imports: [BrowserModule]
})
class MyModule {}

main.ts:
import {MyModuleNgFactory} from './my_module.ngfactory';
import {platformBrowser} from '@angular/platform-browser';

let moduleRef = platformBrowser().bootstrapModuleFactory(MyModuleNgFactory);
Creates an instance of an @NgModule for a given platform using the given runtime compiler.

bootstrapModule<M>(moduleType: Type<M>, compilerOptions: (CompilerOptions & BootstrapOptions) | (CompilerOptions & BootstrapOptions)[] = []): Promise<NgModuleRef<M>>

Parameters
moduleType Type
compilerOptions (CompilerOptions & BootstrapOptions)[] Optional. Default is [].
Returns

Promise<NgModuleRef<M>>


Usage Notes

Simple Example
@NgModule({
  imports: [BrowserModule]
})
class MyModule {}

let moduleRef = platformBrowser().bootstrapModule(MyModule);
Register a listener to be called when the platform is disposed.
