How to Set Up Authentication With AWS Amplify in Next

AWS Amplify is a tool that lets frontend web and mobile developers build and deploy full-stack applications on AWS. We will add the auth feature of Amplify to an already existing front-end web crypto app. The app will allow users to sign in to see the latest crypto prices after signing up. The code for implementing the feature in the next-gen branch of the app is this GitHub branch auth repo. We use the useAuthenticator composable to access the current user signed in during sign-up.
