Answer from AI

Vue Router provides several navigation hooks that allow you to execute code at different points in the routing lifecycle:

  • beforeEach(to, from, next) — a global hook called before each navigation. Can be used for authorization checks or to cancel navigation.
  • beforeResolve(to, from, next) — called after beforeEach and before navigation confirmation, useful for asynchronous operations.
  • afterEach(to, from) — called after navigation is complete, does not have a next parameter, used for logging or analytics.
  • beforeEnter(to, from, next) — a local hook set in route configuration, triggered before entering a specific route.
  • Hooks in components:
    • beforeRouteEnter(to, from, next) — called before entering the route, component is not yet created.
    • beforeRouteUpdate(to, from, next) — called when the route is updated, using the same component.
    • beforeRouteLeave(to, from, next) — called before leaving the route.

Example of using a global hook:

router.beforeEach((to, from, next) => {
  if (to.meta.requiresAuth && !isAuthenticated()) {
    next('/login');
  } else {
    next();
  }
});

These hooks allow flexible navigation management, ensuring security, data loading, and other tasks.
