Ways to grant entry to a Vue.js page exclusively to authenticated users or when localStorage is present

My Vue.js application is set up with vue-router as shown below. index.html

<p>
  <router-link to="/" exact> Home </router-link>
  <router-link to="/about"> About </router-link>
  <router-link to="/contact"> Contact </router-link>
  <router-link to="/login"> Login </router-link>
  <router-link to="/register"> Register </router-link>
</p>
<router-view></router-view>

The routes are defined in the /routes.js file:

import VueRouter from 'vue-router';

let routes = [
  {
    path: '/',
    component: require('./components/Home.vue')
  },
  {
    path: '/about',
    component: require('./components/About.vue')
  },
  {
    path: '/login',
    component: require('./components/Login.vue')
  },
  {
    path: '/register',
    component: require('./components/Register.vue')
  }
];

export default new VueRouter({
  mode: 'history',
  routes
});

In my index.js file, where I initialize the app, I am considering implementing something within the created(){} module. However, I'm unsure about the specifics.

I have the capability to manage sessions and would like to restrict access to a page based on session existence. Can someone advise on how this can be achieved?

One helpful tool for verifying data before transitioning to a new page is Navigation Guards.


When it comes to checking if a user is logged in before moving between pages, Navigation Guards can be quite useful. For example:

If a user is currently on the /home page and wishes to navigate to /dashboard, a Navigation Guard will ensure that the user is logged in before granting access to the /dashboard. If the user is not logged in, they will be redirected to the /login page.

There are various methods for setting user data upon login, but it's important to prioritize system security when implementing these features.

For more information on verifying logged-in users, you can check out this related question. Additionally, this article demonstrates how to perform user authentication using Vuex, which can offer some valuable insights.
