 * Bootstraps an instance of an Angular application and renders a standalone component as the

 *
 * @usageNotes
 * The root component passed into this function *must* be a standalone one (should have the
 * `standalone: true` flag in the `@Component` decorator config).
 *
 * ```typescript
 * @Component({
 *   standalone: true,
 *   template: 'Hello world!'
 * })
 * class RootComponent {}
 *
 * const appRef: ApplicationRef = await bootstrapApplication(RootComponent);
 * ```
 *
 * You can add the list of providers that should be available in the application injector by
 * specifying the `providers` field in an object passed as the second argument:
 *
 * ```typescript
 * await bootstrapApplication(RootComponent, {
 *   providers: [
 *     {provide: BACKEND_URL, useValue: 'https://yourdomain.com/api'}
 *   ]
 * });
 * ```
 *
 * The `importProvidersFrom` helper method can be used to collect all providers from any
 * existing NgModule (and transitively from all NgModules that it imports):
 *
 * ```typescript
 * await bootstrapApplication(RootComponent, {
 *   providers: [
 *     importProvidersFrom(SomeNgModule)
 *   ]
 * });
 * ```
 *
 * Note: the `bootstrapApplication` method doesn't include [Testability](api/core/Testability) by
 * default. You can add [Testability](api/core/Testability) by getting the list of necessary
 * providers using `provideProtractorTestingSupport()` function and adding them into the `providers`
 * array, for example:
 *
 * ```typescript
 * import {provideProtractorTestingSupport} from '@angular/platform-browser';
 *
 * await bootstrapApplication(RootComponent, {providers: [provideProtractorTestingSupport()]});
 * ```
 *
 * @param rootComponent A reference to a standalone component that should be rendered.

 * sanitized so that an attacker cannot inject e.g. a `javascript:` URL that would execute code on
 * the website.
 *
 * In specific situations, it might be necessary to disable sanitization, for example if the

 * Users can bypass security by constructing a value with one of the `bypassSecurityTrust...`
 * methods, and then binding to that value from the template.
 *
 * These situations should be very rare, and extraordinary care must be taken to avoid creating a
 * Cross Site Scripting (XSS) security bug!
 *
 * When using `bypassSecurityTrust...`, make sure to call the method as early as possible and as
 * close as possible to the source of the value, to make it easy to verify no security bug is
 * created by its use.
 *
 * It is not required (and not recommended) to bypass security if the value is safe, e.g. a URL that
 * does not start with a suspicious protocol, or an HTML snippet that does not contain dangerous
 * code. The sanitizer leaves safe values intact.
 *
 * @security Calling any of the `bypassSecurityTrust...` APIs disables Angular's built-in
 * sanitization for the value passed in. Carefully check and audit all values and code paths going
 * into this call. Make sure any user data is appropriately escaped for this security context.
