This repository contains the code for a demo application which was used during my presentation titled "Introduction to AWS IoT Core" at the AWS User meetup organized by Philip Morris in Krakow on September 21st 2022: https://www.youtube.com/watch?v=EXWysnJ7TeU&t=5320s
message_broker_demo.js contains a script showcasing the integration with the Message Broker.
Initially the script subscribes to IoT Core using a wildcard topic.
Afterwards a series of messages are published to a topic matching this wildcard.
Upon receiving the messages through the subscription they are printed.
The client directory contains a React application which simulates an IoT client.
The application allows the sending and receiving of MQTT messages using the Message Broker.
Additionally, it is possible to interact with the Device Shadow API using AWS reserved MQTT topics.
