Upon launching my app, I desire the route /home to be automatically displayed. Unfortunately, the Angular 2 version I am utilizing does not support the "useAsDefault: true" property in route definitions.
To address this issue, I considered implementing the following approach in app.component.ts (a common solution found in various online examples):
export class AppComponent implements OnInit {
constructor(private _router: Router) {}
ngOnInit() {
this._router.navigate(['/home']);
}
}
However, upon attempting this method, I encountered the error message:
"Error:(29, 12) TS2346: Supplied parameters do not match any signature of call target."
After incorporating the Elvis operator, the error was resolved successfully:
export class AppComponent implements OnInit {
constructor(private _router?: Router) {}
ngOnInit() {
this._router.navigate(['/home']);
}
}
If anyone could provide insight into why this is occurring, it would be greatly appreciated. Below is a snippet from my app.component.ts file for reference:
import {Component, OnInit} from '@angular/core';
import {Router, Routes, ROUTER_DIRECTIVES } from '@angular/router';
import {NavbarComponent} from "./navbar.component";
import {UsersComponent} from "./users.components";
import {PostsComponent} from "./posts.component";
import {HomeComponent} from "./home.component";
@Component({
selector: 'my-app',
templateUrl: 'app/app.component.html',
directives: [NavbarComponent, ROUTER_DIRECTIVES]
})
@Routes([
{path: '/home', component: HomeComponent},
{path: '/users', component: UsersComponent},
{path: '/posts', component: PostsComponent}
])
export class AppComponent implements OnInit {
constructor(private _router?: Router) {}
ngOnInit() {
this._router.navigate(['/home']);
}
}
