What are the differences between Vue.js router guards and middleware?

What are the differences between Vue.js router guards and middleware?

Vue.js router guards are specific to the Vue Router and control navigation between routes, while middleware is a broader concept used in various frameworks to handle requests before they reach the final route handler.

Can you give me examples of how to use router guards?

Sure! You can use beforeEach to check authentication before navigating to a route. For example:

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

What about middleware? How does it work in Vue?

In Vue, middleware can be implemented using plugins or by creating functions that run before route handlers. They can be used for logging, authentication, or modifying requests.

Which one is better for handling authentication?

Router guards are generally better for handling authentication in Vue.js because they are specifically designed for route navigation control.
