websocketd (via) Delightfully clever piece of design: “It’s like CGI, twenty years later, for WebSockets”. Simply run “websocketd --port=8080 my-program” and it will start up a WebSocket server on port 8080 and fire up a new process running your script every time it sees a new WebSocket connection. Standard in and standard out are automatically hooked up to the socket connection. Since it spawns a new process per connection this won’t work well with thousands of connections but for smaller scale projects it’s an excellent addition to the toolbok—and since it’s written in Go there are pre-compiled binaries available for almost everything.
