What are the differences between global and local guards in Vue 3 routing?

In Vue 3, global guards are applied to all routes, while local guards are specific to individual routes. Global guards are defined in the router instance, affecting every route, whereas local guards are defined within the route configuration.

Can you give me an example of how to implement a global guard?

Sure! You can implement a global guard using the beforeEach method on the router instance. For example:

router.beforeEach((to, from, next) => {
  // Perform some checks
  next(); // Proceed to the route
});

What about local guards? How do they differ in implementation?

Local guards are defined directly in the route configuration. For example:

const routes = [
  {
    path: '/protected',
    component: ProtectedComponent,
    beforeEnter: (to, from, next) => {
      // Check if user is authenticated
      next(); // Proceed if authenticated
    }
  }
];

When should I use global guards instead of local guards?

Use global guards for checks that apply to all routes, like authentication or logging. Use local guards for route-specific logic.
