Amazon Cognito Auth JS Promises

Wrapper around amazon-cognito-auth-js providing Promise-based APIs for Cognito User Pools authentication in browser apps. Version 1.1.5 (last release Feb 2020) is stable but unmaintained. It supports sign-up, sign-in, sign-out, and token management via OAuth2 flows. Compared to the newer @aws-amplify/auth or amazon-cognito-identity-js, this package offers a lighter, promise-based interface but lacks ongoing updates and TypeScript types. Requires a User Pool App Client ID, App Web Domain, and scope array configured in AWS Console.
