REQUIREMENTS FOR THE EXAMPLES

The example, chat.hs, requires stm-lifted and conduit-combinators which are not dependencies of yesod-websockets. Installing the extra packages needed for the chat.hs example can be installed with the command:

$ cabal install stm-lifted conduit-combinators

The oldest GHC you can use for all examples (chat.hs, chat-with-*.hs, etc.) as of writing this is the one bundled with base-4.11, namely GHC 8.4.

TIMEOUTS

Versions of yesod-websockets prior to 0.2.1 may experience session timeouts after about 30 seconds of inactivity. Refer to the patch in the websockets library which addresses this issue:
