What are the best practices for using routing guards in Vue.js?

When using routing guards in Vue.js, it's important to keep your logic simple and maintainable. You should also ensure that guards are reusable and avoid duplicating code.

Can you give me an example of a reusable routing guard?

Sure! You can create a global guard that checks for user authentication. If the user is not authenticated, redirect them to the login page.

How do I implement a global guard in my Vue.js application?

You can implement a global guard by using the beforeEach method in your router configuration. Here's a simple example:

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

What should I avoid when using routing guards?

Avoid complex logic in your guards, as it can make your code harder to read and maintain. Also, try not to perform heavy operations in guards to keep your navigation smooth.
