Network.Wai.Middleware.RequestLogger

Basic stdout logging

logStdout :: Middleware

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

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.
