## 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:
