I have simple navigation in angular 6 app,

Here is HTML

<nav class="main-nav>
<ul class="main-nav__list " ng-sticky [addClass]="'main-sticky-link'" [ngClass]="ref.click === true? 'Navbar__ToggleShow' :''">
            <li class="main-nav__item">
              <a class="main-nav__link" routerLink="['/']" routerLinkActive="active">Home</a>
            </li>
            <li class="main-nav__item"> 
              <a class="main-nav__link" routerLink="['/about']" routerLinkActive="active">About us</a>
            </li>

          </ul>
</nav>

    CommonModule,
    RouterModule.forRoot(routes),
  ],

I have tried different combination to solve the issue but still not able to get rid of this error,

what am I doing wrong in my code? any help will be helpfull thanks

This question is related to javascript html angular typescript angular-routerlink

The answer is


In case you need the [] syntax, useful for "edit forms" when you need to pass parameters like id with the route, you would do something like:

[routerLink]="['edit', business._id]"

As for an "about page" with no parameters like yours,

[routerLink]="/about"

or

[routerLink]=['about']

will do the trick.


As the error says your router link should match the existing routes configured

It should be just routerLink="/about"
