Overview:

This is a demo application created using Flask and Cognito to display a UI that manages user registration and authentication. There are rendered html pages and REST API endpoints that correspond to the registration, authentication, and authenticated user view.

About AWS Cognito:

AWS Cognito is a service that enables developers to add user sign-up, sign-in, and access control to their web and mobile applications quickly and securely. It supports user authentication, authorization, and user management, allowing integration with social identity providers and enterprise identity providers via SAML 2.0.

Instructions:

Getting the application up and running requires a few steps outlined below.

Setup virtual environment

python3 -m venv venv;
pip install -r requirements.txt;

Export AWS Access Key and Secret Key to environment variables

export AWS_ACCESS_KEY_ID="{ACCESS_KEY_ID_STRING}";
export AWS_SECRET_ACCESS_KEY="{AWS_SECRET_ACCESS_KEY_STRING}";

Create the Cognito User Pool with the Cognito Pool Manager Script

Note: The 'create' keyword after the script is needed. Creating this Data Stream will incur AWS charges

python3 cognito_pool_manager.py create;

Run the Flask App

python3 app.py;

Cleanup:

Once you are done with using the Cognito User Pool, you should delete the instance to stop incurring further charges.

Delete the Cognito User Pool with the Cognito Pool Script
