How to pass parameters to constructor of canActivate?

Issue

I have the following route path:

{
    path: 'teacher',
    component: DashboardTeacher, canActivate: [AccessGuardTeacher('Teacher')]
}

As you can see I tried to pass parameter 'Teacher' in class AccessGuardTeacher:

export class AccessGuardTeacher implements CanActivate {

  constructor(private role: string) {
  }
}

How to do that right?

Solution

Angular 14+ Solution

{
    path: 'edit',
    component: Cmp,
    canActivate: [
      () =>
        inject(Service).hasUserPermissions(['WRITE_SOMETHING'])
          ? true
          : inject(Router).parseUrl('/goSomewhere'),
    ],
  },
