IoT WebSockets in Web Browser with Cognito

Original text for StackOverflow Question:

Does anyone know of any good working examples or tutorials for using AWS IoT as a websocket connection in the browser with AWS Cognito? I've been looking at the AWS IoT Documentation but I've only been able to find server-side examples. If anyone has any experience with this or knows of any good resources please let me know!

How to use AWS IoT to send/receive messages to/from Web Browser

We are trying to use Amazon Web Services Internet of Things (AWS IoT) to send messages from/to a Web Browser (e.g: . Given that the AWS IoT supports JavaScript we expect that this is possible ...

We have searched at the AWS IoT Documentation but only found server-side examples (which expose AWS secrets/keys...)

Are there any good working examples or tutorials for using AWS IoT to send/receive messages via WebSockets/MQTT in the browser (e.g: authenticating with AWS Cognito)? Thanks!

This is the most complete tutorial we have found: http://dev.classmethod.jp/cloud/aws/aws-iot-mqtt-over-websocket/ access in Chrome to get auto-google-translate (its in Japanese...!) 😉

@nelsonic I'm trying to do this exact thing as well and have hit the same wall as you. Did you ever make any progress?

[nelsonic]

@dandonahoe we got the IoT part working: https://github.com/dwyl/chat
the "cognito" part was a bit more effort than we had time for.
if you manage to get it all working we'd love to know how. thanks! 👍

@nelsonic any possibility of making a tutorial? 😛

[nelsonic]

@Tee88 what specifically are you hoping to learn? 🤔

@nelsonic I have multiple IoT things that a generating time-series data. Each device is owned by a different user. Users should be able to monitor sensors readings in real time.How can achieve that using AWS IOT, WebSockets and Cognito?

@nelsonic Hi, could you share what u did on aws console to configure IoT to enable this?

I haven't used aws IoT but aws iot describe-endpoint does return an endpoint which I don't know why it is there.
