Angular 2 Routing run in new tab

Question

I am working with a asp.net core application with angular2 and my routing is working fine.

Answer 1

Try this please, <a target="_blank" routerLink="/Page2">

---

Update1: Custom directives to the rescue! Full code is here: https://github.com/pokearound/angular2-olnw

import { Directive, ElementRef, HostListener, Input, Inject } from '@angular/core';

@Directive({ selector: '[olinw007]' })
export class OpenLinkInNewWindowDirective {
    //@Input('olinwLink') link: string; //intro a new attribute, if independent from routerLink
    @Input('routerLink') link: string;
    constructor(private el: ElementRef, @Inject(Window) private win:Window) {
    }
    @HostListener('mousedown') onMouseEnter() {
        this.win.open(this.link || 'main/default');
    }
}

Notice, Window is provided and OpenLinkInNewWindowDirective declared below:

import { AppAboutComponent } from './app.about.component';
import { AppDefaultComponent } from './app.default.component';
import { PageNotFoundComponent } from './app.pnf.component';
import { OpenLinkInNewWindowDirective } from './olinw.directive';
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { RouterModule, Routes } from '@angular/router';

import { AppComponent } from './app.component';


const appRoutes: Routes = [
  { path: '', pathMatch: 'full', component: AppDefaultComponent },
  { path: 'home', component: AppComponent },
  { path: 'about', component: AppAboutComponent },
  { path: '**', component: PageNotFoundComponent }
];

@NgModule({
  declarations: [
    AppComponent, AppAboutComponent, AppDefaultComponent, PageNotFoundComponent, OpenLinkInNewWindowDirective
  ],
  imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    RouterModule.forRoot(appRoutes)
  ],
  providers: [{ provide: Window, useValue: window }],
  bootstrap: [AppComponent]
})
export class AppModule { }

First link opens in new Window, second one will not:

<h1>
    {{title}}
    <ul>
        <li><a routerLink="/main/home" routerLinkActive="active" olinw007> OLNW</a></li>
        <li><a routerLink="/main/home" routerLinkActive="active"> OLNW - NOT</a></li>
    </ul>
    <div style="background-color:#eee;">
        <router-outlet></router-outlet>
    </div>
</h1>

Tada! ..and you are welcome =)

Update2: As of v2.4.10 <a target="_blank" routerLink="/Page2"> works

Answer 2

In my use case, I wanted to asynchronously retrieve a url, and then follow that url to an external resource in a new window. A directive seemed overkill because I don't need reusability, so I simply did:

<button (click)="navigateToResource()">Navigate</button>

And in my component.ts

navigateToResource(): void {
  this.service.getUrl((result: any) => window.open(result.url));
}

Note:

Routing to a link indirectly like this will likely trigger the browser's popup blocker.

Answer 3

This seems a little confused.

Opening your application in another window or tab will require your entire application to be re-bootstrapped, and then for your router to... pick up that url, convert it into a route, and load the appropriate component.

This is exactly what will happen if you just use a link instead. In fact, that's all that's happening.

The point of the router is to swap components in and out of your router-outlet, which is something that's been bootstrapped and exists within the confines of your running application and isn't shared across multiple windows.

Answer 4

Late to this one, but I just discovered an alternative way of doing it:

On your template,

<a (click)="navigateAssociates()">Associates</a> 

And on your component.ts, you can use serializeUrl to convert the route into a string, which can be used with window.open()

navigateAssociates() {
  const url = this.router.serializeUrl(
    this.router.createUrlTree(['/page1'])
  );

  window.open(url, '_blank');
}

This directive works as a [routerLink] replacement. All you have to do is to replace your [routerLink] usages with [link]. It works with ctrl+click, cmd+click, middle click.

import {Directive, HostListener, Input} from '@angular/core'
import {Router} from '@angular/router'
import _ from 'lodash'
import qs from 'qs'

@Directive({
  selector: '[link]'
})
export class LinkDirective {
  @Input() link: string

  @HostListener('click', ['$event'])
  onClick($event) {
    // ctrl+click, cmd+click
    if ($event.ctrlKey || $event.metaKey) {
      $event.preventDefault()
      $event.stopPropagation()
      window.open(this.getUrl(this.link), '_blank')
    } else {
      this.router.navigate(this.getLink(this.link))
    }
  }

  @HostListener('mouseup', ['$event'])
  onMouseUp($event) {
    // middleclick
    if ($event.which == 2) {

      $event.preventDefault()
      $event.stopPropagation()
      window.open(this.getUrl(this.link), '_blank')
    }
  }

  constructor(private router: Router) {}

  private getLink(link): any[] {
    if ( ! _.isArray(link)) {
      link = [link]
    }

    return link
  }

  private getUrl(link): string {
    let url = ''

    if (_.isArray(link)) {
      url = link[0]

      if (link[1]) {
        url += '?' + qs.stringify(link[1])
      }
    } else {
      url = link
    }

    return url
  }
}
