Angular 2 : multiple HTML pages within same component

Question

I am new to angular 2, I have a component named Register, in this 1 component I have 5 HTML pages where one click of 1st register page I will go to the 2nd register page and on click of 2nd register page I will go to the 3rd register page. How can I make 5 HTML pages in 1 component I means is there a way to achieve multiple templates per component? How to do routing? The main intent is to have separate HTML & SCSS files and routing logic.

As of now I am rendering pages using ngIf which has made my page very lengthy. Is there a way around to achieve this?

<!--View 1-->
        <div class="open-card-BG" *ngIf="registerView=='regView1'">
Register Page 1
</div>
            <!--View 2-->
            <div class="open-card-BG" *ngIf="registrationView=='regView2'">
Register Page 2
</div>


    @Component({
      selector: 'register-page',
      templateUrl: './register-page.component.html',
      styleUrls: ['./register-page.component.scss'],
      providers : [RegisterService,Configuration,LocalStorageService]
    })
        ngOnInit() {
        this.registerView= "regView1";
      }

    changeView(view) {

          this.registerView= view;
      }

      previousView(view) {

          this.registerView= view;
      }

Try do like this :

@Component({
    selector: 'register-page',
    template: `
            <div class="open-card-BG" *ngIf="registerView == 'regView1'">Reg View 1 Content</div>
            <div class="open-card-BG" *ngIf="registerView == 'regView2'">Reg View 2 Content</div>
            `,
    styleUrls: ['./register-page.component.scss'],
    providers: [RegisterService, Configuration, LocalStorageService]
})

export class Appcomponent {
    registerView = 'regView1';
}

Else do like this

page1.component.html

<div>
    <h1>Page1 Component Content</h1>
</div>

page2.component.html

<div>
    <h1>Page2 Component Content</h1>
</div>

home.component.html

<div>
    <div class="open-card-BG" *ngIf="registerView == 'regView1'">
         <app-page1-component></app-page1-component>
    </div>
    <div class="open-card-BG" *ngIf="registerView == 'regView2'">
         <app-page2-component></app-page2-component>
    </div>
</div>

component.ts

@Component({
    selector: 'app-home',
    templateUrl: './home.component.html',
    styleUrls: ['./home.component.css']
})

export class HomeComponent {
    registerView = 'regView1';
}

Using *ngIf would be the most sensible way to do this. If it gets to the point that you are having to use *ngIf to cover large chunks of HTML then it's probably more of an indication that these should be separate components since they clearly have significantly different views.

If there is a lot of shared logic in your .ts files you can make a class with all the shared logic and use class inheritance on your individual components.

export class BaseComponentLogic implements OnInit {

    ...

}

@Component({...})
export class MyFirstComponent extends BaseComponentLogic implements OnInit {

   ...
}

@Component({...})
export class MySecondComponent extends BaseComponentLogic implements OnInit {

   ...
}
