type ModLogger = LogFunc Source #

type Formatter = TimedFastLogger -> CallStack -> LogSource -> LogLevel -> Utf8Builder -> IO () Source #

jsonFormatter :: Text -> Text -> Formatter Source #

Builds LogMessage and json encodes to string

newLogger :: LogType -> Formatter -> IO (TimedFastLogger, ModLogger) Source #

Creates a logger module using a given formatting function. | Also returns the underlying TimedFastLogger for use outside of your app (e.g. in some WAI middleware).

buildLogger :: Text -> Text -> IO ModLogger Source #

Convenient function to create json formatted logger with appName & appVer values
