Reload app if the authentication is successful

To reload your app after successful authentication using Amplify Gen 2 with Vue, you can implement a custom handler for the authentication process. Here's how you can achieve this:

1. Use the Authenticator component provided by Amplify UI.

2. Implement a custom handler for the "Sign In" action. This handler will be triggered after a successful authentication.

3. In this handler, you can add logic to reload the page or app.

Here's a basic implementation:

<template>
  <Authenticator :services="services">
    <!-- Your app content -->
  </Authenticator>
</template>

<script>
import { Authenticator } from '@aws-amplify/ui-vue';
import { Auth } from 'aws-amplify';

export default {
  components: { Authenticator },
  data() {
    return {
      services: {
        async handleSignIn(formData) {
          try {
            // Perform the sign-in
            const user = await Auth.signIn(formData.username, formData.password);
            
            // If sign-in is successful, reload the page
            if (user) {
              window.location.reload();
            }
            
            return user;
          } catch (error) {
            console.error('Error during sign in:', error);
            throw error;
          }
        }
      }
    };
  }
}
</script>

In this example, we're using a custom handleSignIn method. After a successful sign-in, it calls window.location.reload() to refresh the entire page. This approach ensures that your app reloads and re-initializes with the new authentication state.

Remember to adjust this code according to your specific app structure and requirements. Also, ensure that you have properly configured Amplify in your Vue app for this to work correctly.

If you prefer a more granular approach without reloading the entire page, you could instead emit a custom event after successful authentication and handle the app state update in your Vue components. This would allow you to refresh only specific parts of your app that depend on the authentication state.

Here's a solution that works:

function AuthStateListener({ children }) {
      // subscribe just to the route change
  const { route } = useAuthenticator(ctx => [ctx.route]);
  const router = useRouter();

  useEffect(() => {
    if (route === 'authenticated') {
      // next/navigation: use router.refresh() to re-fetch server data
      // next/router: use router.reload() for full reload
      if (router.refresh) {
        router.refresh();
      } else {
        window.location.reload();
      }
    }
  }, [route, router]);

  return <>{children}</>;
}

Then wrap your SSR components and they'll refresh automatically upon login:

<AuthStateListener>
    <MySsrComponent/>
</AuthStateListener>
