Making connections with TCP and Sockets for Workers
Making connections with TCP and Sockets for Workers2021-11-15 Today we are excited to announce that we are developing APIs and infrastructure to support more TCP, UDP, and QUIC-based protocols in Cloudflare Workers. Once released, these new capabilities will make it possible to use non-HTTP socket connections to and from a Worker or Durable Object as easily as one can use HTTP and WebSockets today

A Million WebSockets and Go
By Sergey Kamardin Hi everyone! My name is Sergey Kamardin and I’m a developer at Mail.Ru. This article is about how we developed the high-load WebSocket server with Go. If you are familiar with WebSockets, but know little about Go, I hope you will still find this article interesting in terms of ideas and techniques for performance optimization. 1.

How to detect if a user left a Phoenix channel due to a network disconnect?
I have an Elixir/Phoenix server app and the clients connect through the build in channels system via websockets. Now I want to detect when an user leaves a channel. Sidenote: I'm using the javascript client library inside a Google Chrome Extension. For this I extracted the ES6 code from Phoenix, transpiled it to javascript, and tweaked it a little so it runs standalone. Now when I just close the p
