How do I use async/await in Vue routing guards?

You can use async/await in Vue routing guards by defining your guard as an async function. This allows you to handle asynchronous operations like API calls before navigating.

Can you show me a code example?

Sure! Here's a simple example:

const router = new VueRouter({
  routes: [
    {
      path: '/protected',
      beforeEnter: async (to, from, next) => {
        const isAuthenticated = await checkAuth();
        if (isAuthenticated) {
          next();
        } else {
          next('/login');
        }
      }
    }
  ]
});

What if I need to handle errors in the guard?

You can use a try-catch block within your async function to handle errors. For example:

beforeEnter: async (to, from, next) => {
  try {
    const isAuthenticated = await checkAuth();
    if (isAuthenticated) {
      next();
    } else {
      next('/login');
    }
  } catch (error) {
    console.error('Error during authentication:', error);
    next('/error');
  }
}
