/**
|
||
|
|
* Bootstrapping for Angular applications.
|
||
|
|
*
|
||
|
|
* You instantiate an Angular application by explicitly specifying a component to use
|
||
|
|
* as the root component for your application via the `bootstrap()` method.
|
||
|
|
*
|
||
|
|
* ## Simple Example
|
||
|
|
*
|
||
|
|
* Assuming this `index.html`:
|
||
|
|
*
|
||
|
|
* ```html
|
||
|
|
* <html>
|
||
|
|
* <!-- load Angular script tags here. -->
|
||
|
|
* <body>
|
||
|
|
* <my-app>loading...</my-app>
|
||
|
|
* </body>
|
||
|
|
* </html>
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* An application is bootstrapped inside an existing browser DOM, typically `index.html`.
|
||
|
|
* Unlike Angular 1, Angular 2 does not compile/process providers in `index.html`. 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}.
