What it is ?

Demo of AWS Cognito based authentication client + server application.

The client triggers authentication of user, and stores user's session. It also performs calls to backend, which is able to verify the token to check if user is authenticated.

There is also authorization example, that checks for existence for a specific group in user's data.

Client

React based SPA.

Backend

Simple Node.js "REST" api.

AWS Services

Cognito as Identity and User Pool. It provides authentication via OAUTH 2.0 OpenID Connect.

Local - Development

yarn install
yarn start

It starts the client listening on http://localhost:3000 and the server listening http://localhost:3001
