Best practice to use WebSocket

[cflorion]

Hi,

I am asking my question here because there is no Discussions tabs on https://github.com/hummingbird-project/hummingbird-websocket.

This is the first time I use Websocket via Swift-NIO and I am a bit lost.
I usually use https://github.com/Building42/Telegraph.
Telegraph keeps an array of the connected webSockets so when I need to send then data, I loop over the array of connected webSockets and send them data individually.

With Hummingbird I am not sure how I should implement this behaviour.

app.ws.addUpgrade()
app.ws.add(middleware: HBLogRequestsMiddleware(.info))
app.ws.on("/ws") { [weak self] req, ws in
    ws.initiateAutoPing(interval: .seconds(60))
    ws.onClose { [weak self] (ws) in
    }
}

I wanted to create my own array of connected webSockets. When app.ws.on("/ws") is called, I add ws to my array. When ws.onClose {...} is called I remove ws from my array.
But the webSocket object is not Hashable and have not unique identifier so I don't know how to remove it from the array.

I may have mistunderstood how webSockets work with NIO. Does someone have already done this ?
Thanks

Yes the websocket code doesn't have any support for storing connections. I have left that up to you. The websocket chat example in hummingbird-examples has a basic connection manager https://github.com/hummingbird-project/hummingbird-examples/blob/main/websocket-chat/Sources/App/ConnectionManager.swift

Makes sense! Thanks
