How can I implement authentication in Vue 3?

To implement authentication in Vue 3, you can use libraries like Vue Router for routing and Vuex for state management. You can also integrate with authentication services like Firebase or Auth0.

What are the steps to set up Vue Router for protected routes?

First, install Vue Router, then define your routes. Use navigation guards to protect routes by checking if the user is authenticated before allowing access.

Can you show me an example of a login component?

Sure! Here's a simple login component example:

<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>

What about handling user roles and permissions?

You can manage user roles by storing them in your authentication state and using conditional rendering in your components to show or hide features based on the user's role.
