Readme for ghci-websockets-0.0.1

[back to package description]


With ghci-websockets you can send data from GHCi straight to the browser, using a websocket connection that survives GHCi reloads.



The Ghci.Websockets module implements the actual websocket server, broadcasting JSON objects to all clients. Ghci.Websockets.Simple adds a custom message type for text, HTML, and plots on top of that.



This packages uses the foreign-store package internally, which is highly unstable. I wouldn't use ghci-websockets for anything other than GHCi.
