Question

What are the steps to restrict a user from accessing a specific website?

In my Vue.js project, I've implemented a function that hides a specific menu item for users with insufficient permissions:

<a :href="href" @click="navigate" v-if="hideMenuItem()">
    // some code
</a>

hideMenuItem() {
    if(currentUser.permission == 'All') {
      return true;
    } else return false; 
}

This successfully hides the element on the UI, preventing the user from accessing a certain page by clicking on an anchor link. However, there is a loophole where the user can still access the page by directly entering the URL in their browser. How can I prevent this?

Any help would be appreciated. Thank you!

To achieve this functionality, it is essential to utilize Vue Router and set up validation within the beforeEach loop as outlined in the documentation on [Navigation Guards]: https://router.vuejs.org/guide/advanced/navigation-guards.html#global-before-guards

Here is an example of how you can implement it:

router.beforeEach(async (to, from, next) => {
  const currentUser = store.state.currentUser
  if (currentUser.permission !== 'All') {
    next(loginPage)
  } else {
    next()
  }
})

To implement this logic for a specific page, consider using Navigation guards. You can find more information about Navigation Guards here.

When setting up routes in your routes file, include metadata to control access:

{
    path:'/yourPath',
    meta:{guest:false},
    component:YourComponent
}

Here's an example of redirecting users to the /login page if they are not authenticated:

// INCORRECT
router.beforeEach((to, from, next) => {
  if (to.name !== 'Login' && !isAuthenticated) next({ name: 'Login' })
  // calling `next` twice when user is unauthenticated
  next()
})
// CORRECT
router.beforeEach((to, from, next) => {
  if (to.name !== 'Login' && !isAuthenticated) next({ name: 'Login' })
  else next()
})
