How do I implement authentication and routing in Vue 3?

To implement authentication in Vue 3, you can use libraries like Vue Router for routing and Vuex for state management. First, set up Vue Router to manage your routes, then create a login component that handles user authentication.

What are the steps to set up Vue Router?

First, install Vue Router using npm. Then, create a router instance and define your routes. Finally, add the router to your Vue instance.

Can you show me an example of a login component?

Sure! Here's a simple login component:

<template>
  <form @submit.prevent="login">
    <input v-model="username" placeholder="Username" />
    <input v-model="password" type="password" placeholder="Password" />
    <button type="submit">Login</button>
  </form>
</template>
<script>
export default {
  data() {
    return {
      username: '',
      password: ''
    };
  },
  methods: {
    login() {
      // Handle login logic here
    }
  }
};
</script>

How do I protect certain routes from unauthorized access?

You can use navigation guards in Vue Router. Define a guard that checks if the user is authenticated before allowing access to certain routes.
