How can I implement authentication in a Vue.js app using vue-resource?

To implement authentication in a Vue.js app using vue-resource, you can follow these steps: 1. Install vue-resource. 2. Set up your API endpoints for login and registration. 3. Use vue-resource to make HTTP requests to these endpoints. 4. Store the authentication token in local storage or Vuex. 5. Create a navigation guard to protect routes.

Can you show me an example of how to make a login request?

Sure! Here's a simple example:

this.$http.post('https://yourapi.com/login', { username, password })
  .then(response => {
    localStorage.setItem('authToken', response.data.token);
    this.$router.push('/dashboard');
  })
  .catch(error => {
    console.error('Login failed:', error);
  });

What should I do if the login fails?

If the login fails, you should handle the error in the catch block. You can display an error message to the user, like this:

.catch(error => {
  this.errorMessage = 'Invalid credentials, please try again.';
});

How can I protect my routes after logging in?

You can use navigation guards in Vue Router. For example:

router.beforeEach((to, from, next) => {
  const isAuthenticated = !!localStorage.getItem('authToken');
  if (to.matched.some(record => record.meta.requiresAuth) && !isAuthenticated) {
    next({ path: '/login' });
  } else {
    next();
  }
});
