Parent Route Abstractions in Vue-Router

I am currently in the process of transitioning my existing website to vuejs. The navigation structure I aim for is as follows:

/login
/signup
/password-reset
/browse
/search
... numerous other paths

Since some of these paths have similar functionalities, I decided to group them under parent routes as children:

[{ // public routes
  path: '/', 
  component: Auth,
  children: [
    { path: '/login', component: Login },
    { path: '/signup', component: Signup },
    { path: '/password-reset', component: PasswordReset },
  ]
}, 
{ // authenticated routes
  path: '/', 
  component: Home,
  children: [
    { path: '/browse', component: Browse },
    { path: '/search', component: Search }
  ]
}]

The issue that arises is clear: both the Auth and Home base components share the same route path which leads to routing errors. Given that there will be a significant number of routes with shared base components and functionalities, I seek to designate them as children of abstract states to avoid conflicts.

Question 1: How can I effectively incorporate these routes along with their parent abstract states without causing conflicts or needing to implement redundant logic in the children components?

Question 2: Is there a way to prevent the parent states from being directly accessible routes, or if they are accessible, automatically redirect to a child state?

Answer №1

When multiple routes share the same path, priority is given to the first route in the array. Therefore, it is important to place the Home route before the Auth route to ensure that the / path always matches the Home route and not the Auth route. This setup also guarantees that direct routing to the Auth route is impossible, which aligns with your desired outcome.

If you wish to restrict access to the Home route, you can specify a redirect action when an exact match is found:

{
  path: '/',
  component: Home,
  redirect: '/browse',           // Redirect to path, or
  redirect: { name: 'browse' },  // Redirect to named route
  children: ...
}

If the Auth component does not have any authentication-specific user interface, you may opt against using "abstract" routes for enforcing authentication. There are various methods available in vue-router to achieve this; one approach is outlined below:

// Routes

{
  path: '/profile',
  component: Profile,
  meta: { auth: true },
}

// Router hooks

router.beforeEach((to, from, next) => {
  if (to.matched.some(route => route.meta.auth) && !authenticated) {
    next('/login');
  } else {
    next();
  }
});
