How do I implement authentication in a Vue CLI app using Axios?

To implement authentication in a Vue CLI app using Axios, you can follow these steps: 1. Set up your Vue project with Vue CLI. 2. Install Axios using npm. 3. Create a service for API calls. 4. Use Axios to send login requests to your backend. 5. Store the authentication token in local storage.

Can you show me a code example for the login request?

Sure! Here's a simple example:

import axios from 'axios';

const login = async (credentials) => {
  try {
    const response = await axios.post('https://yourapi.com/login', credentials);
    localStorage.setItem('token', response.data.token);
    return response.data;
  } catch (error) {
    console.error('Login failed:', error);
    throw error;
  }
};

This function sends a POST request with user credentials and stores the token.

What should I do after logging in?

After logging in, you should redirect the user to a protected route and set up Axios to include the token in the headers for subsequent requests. You can do this by creating an Axios instance with interceptors.

How do I protect routes in Vue Router?

You can protect routes in Vue Router by using navigation guards. Check if the user is authenticated before allowing access to certain routes.
