Managing logout feature effectively in Vue.js/LaravelEnsuring proper logout functionality

I'm currently in the process of building a simple SPA with Vue and Laravel. So far, I've managed to set up user registration and login functionalities.

However, one thing that's stumping me is how to implement a logout feature.

Here's what my current setup looks like:

AuthController.php:

public function logout()
{
        $accessToken = auth()->user()->token();

        $refreshToken = DB::table('oauth_refresh_tokens')
        ->where('access_token_id', $accessToken->id)
        ->update([
            'revoked' => true
        ]);

        $accessToken->revoke();

        return response()->json(['status' => 200]);
}

routes/api.php:

Route::middleware('auth:api')->group(function () {
    Route::post('/logout', 'API\AuthController@logout');
    Route::get('/get-user', 'API\AuthController@getUser');
});

So far, here's what I've attempted:

Layout.vue:

methods: {
            logout() {
                axios.post('/api/logout').then(response => {
                    this.$router.push("/login")

                }).catch(error => {
                    location.reload();
                });
            }
 }

This method invokes my logout function in Auth.js:

logout() {
    localStorage.removeItem('token')
    localStorage.removeItem('expiration')
}

Unfortunately, when users click on the logout button, they're not immediately logged out (or redirected to the login page) – they can still access "user only pages". A manual page refresh seems to be required for proper log out.

Can someone offer guidance on this? Is this the correct way to implement a secure logout mechanism?

Although it may be considered outdated, I recently delved into Laravel and Vue development and successfully implemented a simple logout feature. By leveraging the built-in authentication system of Laravel, you can mimic the logout action in app.blade.php as follows:

<b-dropdown-item href="#" onclick="event.preventDefault(); document.getElementById('logout-form').submit();">Sign Out</b-dropdown-item> //this replaces a standard <a> tag
<b-form id="logout-form" action="logout" method="POST" style="display: none;">
   <input type="hidden" name="_token" :value="csrf">
</b-form>

To make this functionality work, ensure that the csrf token is accessible within your script data object like so:

export default {
 data() {
   return {
     csrf: document.querySelector('meta[name="csrf-token"]').getAttribute('content')
   }
 },
 methods: {
   submit : function(){
     this.$refs.form.submit();
   }
 }
}

Additionally, include a meta csrf tag in the head section of your blade.php file:

<meta name="csrf-token" content="{{ csrf_token()}}">

This setup assumes that you will integrate the logout functionality in your navbar .vue component.

Although I haven't personally worked with Laravel, it seems like handling logouts on the client side is feasible without requiring any backend changes. By removing the auth token from local storage, the user will no longer have access to protected data.

It appears that when you refresh the page, your getUser function is called, resulting in being logged out only at that moment. This occurs because an empty token is sent to your backend server, which is unable to find a user associated with it and returns a default guest object. To complete the logout process, make sure to clear the user state after deleting the token in your logout() function or send a request to the /get-user endpoint.

For logging out, make sure to have axios installed and then follow the steps below in Laravel versions 6*, 7*, or 8*:

npm install axios

Lastly, use this code to trigger the logout function upon clicking:

axios.post("logout").then(response => { 
   console.log(response);
})
.catch(error => {
   console.log(error);
});

When it comes to handling logout links, my preference is to send a request to Laravel in order to invalidate the current user's (Passport JWT) token.

Here's the method I am using:

On the backend:

AuthController.php

Within this file, I have created a logout method:

  ...

  public function logout(Request $request) {
    $request->user()->token()->revoke();

    return response()->json([
       'message' => 'Successfully logged out'
    ]);
  }

routes/api.php

I have set up a route that requires authentication for access.

Route::group(['middleware' => 'auth:api'], function() {
  ...

  Route::get('/logout', 'AuthController@logout');
});

On the frontend:

In this case, I am utilizing Vue's single file components

App.vue

<template>
  <nav>
    <ul>
      ...
        <li v-if="isLoggedIn">
          <a id="logout-link" href="#" @click.prevent="logout">Logout</a>
        </li>
    </ul>
  </nav>
  ...
</template>

<script>
export default {
   ...
   methods: {
     logout(evt) {
       if(confirm("Are you sure you want to log out?")) {
         axios.get('api/logout').then(response => {
          localStorage.removeItem('auth_token');
          
          // Remove any other authenticated user data stored in local storage

          // If you previously set this for subsequent Ajax requests:
          // axios.defaults.headers.common['Authorization'] = 'Bearer ' + auth_token ;
          delete axios.defaults.headers.common['Authorization'];

          // Redirect to login page if using 'vue-router'
          this.$router.go('/login');
        })
        .catch(error => {
          // Even if the api request fails, consider clearing
          // the same data from localStorage
          // This can be done in a finally method to avoid duplication
          localStorage.removeItem('auth_token');
          delete axios.defaults.headers.common['Authorization'];
          this.$router.go('/login');
        });       
       }
     }
   }
}
</script>

The purpose of this approach is to revoke the token on the backend when logging out. However, this step may not be necessary if the token has a short expiration period.
