Flutter Tutorial: How to build a web socket API on AWS. Part 2 - Implementation on AWS

Hands-on tutorial and walk-through on how to connect to the AWS server less backend using websockets. Websockets provide real-time low-latency communications in both directions between front- and back-end. However, implementation and communication is different than REST APIs. In part 2 of the mini-series, I explain what needs to be configured and built on AWS, using the API Gateway, Lambda (Node JS), DynamoDB and Cognito. I walk through the implementation on AWS and demonstrate the session management.
