Synopsis

Basic stdout logging

logStdout :: Middleware Source

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

logStdoutDev :: Middleware Source

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.
