Vue Router - Unauthorized access guard error

Vue Router - Unauthorized access guard error

I'm facing a problem with my navigation guard where the IDE is showing an error stating that requiresAuth is an unresolved variable.

router.beforeEach(async (to, from, next)=>{
    if(to.matched.some((record)=> record.meta.requiresAuth)){
        const currentUser = await getCurrentUser();
        if(await currentUser){
            next()
        }
        else{
            next("/about")
        }
    }
});

This issue arises in my router setup, particularly in the second route which has the meta object containing the requiresAuth property that is unresolved.

const router = createRouter({
    history:createWebHistory(),
    routes:[
        {
            path:"/",
            name:"Home",
            component:Home,
        },
        {
            path:"/dashboard",
            component: Dashboard,
            meta:{
                requiresAuth:true,
            }
        }

    ]
})

Upon starting up the app, I encounter the following console error:

Error: Invalid navigation guard at vue-router.mjs:2008:47

The code fails to proceed beyond the first if statement in the beforeEach hook due to the unresolved requiresAuth variable.

Answer №1

It seems that the issue lies in the fact that not all paths of your navigation guard are calling the next() function

All your code is contained within a single if statement. If this initial if condition is not met, vue-router will not know how to proceed.

router.beforeEach(...) {
  if (to.matched...) {
    if(user) {
      next()
    } else {
      next('/about')
    }
  }
  // Error occurs here
}

Mistakes like these highlight why using the next function is not strongly recommended and is only optionally supported in vue-router 4.

The solution, however, is straightforward. Simply ensure that outside of the initial if statement, the very last line of code includes another call to next()
