Like in real life, there is no chat history or account setup. If you want to test the service, feel free to message me: https://app.cannon-chat.online/#/newcontact?deviceId=neatly-... |
Presumably, your server stores a registry of Device IDs and IPs to route messages? What about replacing this with some sort of partitioned DHT to make it decentralized?
Also, the messages flow through your servers? Would it be possible to set up WebSocket connections between the users instead, and how would that compare from a security model perspective?
I don't really know much about any of this, so I'm just asking out of curiosity.
> Presumably, your server stores a registry of Device IDs and IPs to route messages?
Not IPs but Push API registration objects.
> What about replacing this with some sort of partitioned DHT to make it decentralized?
I guess this could be done but it's a task I can't tackle at this point.
> Also, the messages flow through your servers?
Yes but I don't store them. My API just dispatches the message to the recipient's push service. Which means the message exists on my server only in the form of an in-memory variable for several microseconds between being received and sent further.
> Would it be possible to set up WebSocket connections between the users instead, and how would that compare from a security model perspective?
This generally can't be done in a PWA. OS won't allow a persistent WebSocket to run in background.
Also, this would disclose too much information about a client to all the other clients. Currently, all I know about other clients is their Device IDs which are just random strings.
contact for testing at your own risk...
Just a heads up for those testing it out on iOS: "Why can't I reply directly through the push notification? Because your browser that doesn't offer this capability. For example, Safari on iOS doesn't support this feature."
