Coast comes with a relatively simple (i.e. not feature-packed) logger.
The goal was to adhere to the 12factor app rules and not really worry about logging.
All requests and responses are logged to stdout and look a little something like this:
2019-03-02 10:56:58 -0700 GET "/" :home/index 200 text/html 4ms
The format is more generally:
handler keyword called
response content type
It's old school, but don't be afraid to use
println if you get stuck for any reason.
The logger may grow up in the future, the goal may be to copy well-known frameworks' loggers, but for now, this will do.
