Use proper logging

[acelaya]

The server is currently logging some lines via console.log. Use a proper logging service instead.

Using console.log should actually be fine IMO. If you run the app in a container the logs can be flexibly forwarded to any log monitoring service of your choice. If you, however, incorporate that directly into the app, you will add a (maybe later difficult to remove) dependency and add extra load to the app and you might not be able to trace back the log event to the running container instance (if you have multiple instances). In any case, the biggest challenge is to decide which info goes into which channel (debug, warn, log, error), such that the logs can be meaningfully filtered and do not flood your monitoring.

Btw.: Great work! 🚀 If you'd drop a CONTRIBUTING.md file to know how to contribute that would be awesome and also maybe label issues with "contribution welcome" or so.
