Streaming response disconnect hook
I'm experimenting with a worker that responds with an indefinite
ReadableStream - for the sake of this example, let's just say that it sends the current time as a string every second. I'd like to know when the client manually disconnects, and when that happens, write the number of messages I've sent until that point to a data store. Is there any way to achieve this reliably with Workers? I'm primarily interested in Rust, but would also be interested in a TS/JS solution.1 Reply
There's no way to detect a client disconnect today, it's something that has come up before though
I'd recommend filing a discussion on workerd: https://github.com/cloudflare/workerd/discussions
