feat(angular): support binding routing data to component inputs (#27694)
Issue number: Resolves #27476 --------- <!-- Please do not submit updates to dependencies unless it fixes an issue. --> <!-- Please try to limit your pull request to one type (bugfix, feature, etc). Submit multiple pull requests if needed. --> ## What is the current behavior? <!-- Please describe the current behavior that you are modifying. --> Ionic Angular application on Angular v16 cannot use the [`bindToComponentInputs`](https://angular.io/api/router/ExtraOptions#bindToComponentInputs) feature to assign route parameters, query parameters, route data and route resolve data to component inputs. ## What is the new behavior? <!-- Please describe the behavior or changes that are being added by this PR. --> - Ionic Angular developers can use the option on `RouterModule.forRoot` to enable the Angular feature for binding the route snapshot data to the component inputs. **Modules** ```ts @NgModule({ imports: [ RouterModule.forRoot([/* your routes */], { bindToComponentInputs: true // <-- enable this feature }) ] }) export class AppModule { } ``` **Standalone** ```ts import { withComponentInputBinding } from '@angular/router'; bootstrapApplication(App, { providers: [ provideRouter(routes, //... other features withComponentInputBinding() // <-- enable this feature ) ], }); ``` With this feature enabled, developers can bind route parameters, query parameters, route data and the returned value from a resolver to input bindings on their component. For example, with a route configuration of: ```ts RouterModule.forChild([ { path: ':id', data: { title: 'Hello world' }, resolve: { name: () => 'Resolved name' }, loadComponent: () => import('./example-component/example.component').then(c => c.ExampleComponent) } ]) ``` and a component configuration of: ```ts @Component({ }) export class ExampleComponent { @Input() id?: string; @Input() title?: string; @Input() name?: string; @Input() query?: string; } ``` Navigating to the component with a url of: `/2?query=searchphrase` The following would occur: - `id` would return `2` - `title` would return `Hello world` - `name` would return `Resolved name` - `query` would return `searchphrase` ## Does this introduce a breaking change? - [ ] Yes - [x] No <!-- If this introduces a breaking change, please describe the impact and migration path for existing applications below. --> ## Other information <!-- Any other information that is important to this PR such as screenshots of how the component looks before and after the change. --> This PR will need to be targeted to a minor release once a design doc is approved by the team. Dev-build: `7.1.3-dev.11689276547.129acb40`
