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

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

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

Sure! You can implement a global guard using the beforeEach method in your router setup. For example:

router.beforeEach((to, from, next) => {
  // Perform checks here
  next(); // Call next() to 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 access here
      next();
    }
  }
];

When should I use global guards instead of local ones?

Use global guards for checks that apply to all routes, like authentication. Use local guards for route-specific logic, like permissions for a particular page.
