A simple logging middleware for WAI applications that supports the 'log-*' family of packages: https://hackage.haskell.org/package/log-base

Currently there are no logging options but contributions are welcome. When logging to stdout, the output looks like this:

2019-02-21 19:51:47 INFO my-server: Request received {
  "url": "/api/myapi",
  "body-length": "KnownLength 0",
  "method": "GET",
  "user-agent": "curl/7.54.0",
  "remote-host": "127.0.0.1:61249"
}
2019-02-21 19:51:47 INFO my-server: Sending response
