Question

What steps can be taken to ensure Vue application admin page contents are not displayed without proper authentication?

By implementing role-based authentication in Vue app, we can efficiently manage routes and components visibility between regular users and administrators.

As the number of roles increases, the application size grows, making it challenging to control CRUD operations effectively.

I am exploring a secure model setup where user/admin content is not served to the browser until authentication is verified. This includes ensuring that JavaScript scripts are not loaded.

My suggestion involves using a simple HTML page with redirection to a separate application containing a JWT token with user details for enhanced security.

Is this approach viable or is there a more efficient way to accomplish this in Vue? Should Express be integrated to load server contents post-login?

I am seeking an example or reference material on building a secure application.

Furthermore, I am interested in methods to clear the browser cache after logging out or when the token expires.

When faced with a code base that is becoming unmanageable, creating a new Vue instance or application can help simplify things; however, vue.js offers tools to maintain tidy code, even with diverse roles and routes.

In the router file (index.js in the src/ router directory), you can implement router guards to control access to certain routes based on specific conditions:

path: "/uploadavatar",
    name: "UploadAvatar",
    component: () =>
      import(
        /* webpackChunkName: "uploadavatar" */ "../views/UploadAvatar.vue"
      ),
    beforeEnter(routeTo, routeFrom, next) { 
    // Perform necessary checks here, such as user roles
    }

If feasible, explore using router guards to meet your requirements.

Managing state across various objects in the application can be challenging without Vuex, especially when dealing with different roles. Vuex serves as a central store for application state, ensuring changes made by one component are reflected throughout the entire application, providing a seamless flow of data among components and views.

Utilizing Vuex is crucial for role-based security as it maintains a 'single source of truth' for application data, reducing the risk of unauthorized access due to inconsistencies in authentication status across components.

Embracing both router guards and Vuex offers flexibility and simplifies your application structure:

For handling granular component behavior tied to roles, organizing code within each component methodically for clarity and ease of maintenance is recommended.

Let's create a pair of functions to handle authentication verification.

import Login from '@/components/Auth/Login';
import AdminContents from '@/views/user/admin/contents';
import Home from '@/components/Home/Home';
import Vue from 'vue';
import Router from 'vue-router';
import store from '../store';

Vue.use(Router);

const checkAuthentication = (to, from, next) => {
  if (store.getters['auth/isAuthenticated']) {
    return next();
  }
  return next('/login');
};

const checkNotAuthenticated = (to, from, next) => {
  if (!store.getters['auth/isAuthenticated']) {
    return next();
  }
  return next('/');
};

const router = new Router({
mode: 'history',
routes: [
  {
    path: '/login',
    name: 'Login',
    component: Login,
    beforeEnter: checkNotAuthenticated,
  },
  {
    path: '/',
    component: Home,
    children: [
     {
      path: '/admin-contents',
      name: 'admincontents',
      component: AdminContents,
      beforeEnter: checkAuthentication,
     },
    ],
  },
 ],
});
