"Ferret Chat" is a real-time chat project that takes advantage of MQTT over Websockets through AWS IoT. It uses restricted permission credentials to establish a connection over a signed URL (SigV4), using Paho as the client.
The project also includes a very simple client interface for letting you chat.
-
Launch the Cloudformation to setup an IAM User with restricted permissions as well as an IoT Thing (which provides an endpoint you can connect to).
-
Copy the outputs from the Cloudformation, whilst will provide a set of AWS Credentials which will be used to connect to the "chat room".
-
In the AWS IoT Console, copy the host domain name for the Thing, ie.
my-endpoint.iot.us-east-1.amazonaws.com -
Load up
client/index.htmlin your browser. -
Enter in the IoT Endpoint, the copied Access Key and Secret and hit connect.
-
Once connected, the interface will send a message to the chat room telling everyone that you've connected.
-
Connect using multiple tabs or browsers to increase the number of participants.
