What are routing guards in Vue.js and how do I use them?

Routing guards are functions that control access to routes in a Vue.js application. They can be used to protect routes, redirect users, or perform checks before entering a route.

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

Sure! You can define a beforeEnter guard in your route configuration like this:

const routes = [
  {
    path: '/protected',
    component: ProtectedComponent,
    beforeEnter: (to, from, next) => {
      const isAuthenticated = // your authentication logic;
      if (isAuthenticated) {
        next();
      } else {
        next('/login');
      }
    }
  }
];

What other types of guards are there?

In addition to beforeEnter, there are global guards like beforeEach, afterEach, and route-specific guards like beforeRouteEnter, beforeRouteUpdate, and beforeRouteLeave.

How do I test if my routing guards are working?

You can test routing guards by trying to navigate to protected routes without authentication and checking if the redirection works as expected.
