logStdout :: Middleware

Production request logger middleware. Implemented on top of logCallback, but prints to stdout

logCallback

Arguments

:: (ByteString -> IO ())

A function that logs the ByteString log message.

-> Middleware

Prints a message using the given callback function for each request. Designed for fast production use at the expense of convenience. In particular, no POST parameter information is currently given

This is lower-level - use logStdout unless you need this greater control

logStdoutDev :: Middleware

Development request logger middleware. Implemented on top of logCallbackDev, but prints to stdout

Flushes stdout on each request, which would be inefficient in production use. Use logStdout in production.

logCallbackDev

Arguments

:: (ByteString -> IO ())

A function that logs the ByteString log message.

-> Middleware

Prints a message using the given callback function for each request. This is not for serious production use- it is inefficient. It immediately consumes a POST body and fills it back in and is otherwise inefficient

This is lower-level - use logStdoutDev unless you need this greater control

Deprecated

logHandle :: (ByteString -> IO ()) -> Middleware

logHandleDev :: (ByteString -> IO ()) -> Middleware
