Logging

Could just use default console.log and console.error and then use bash redirects to a file

node index.js > regular.log 2> error.log

Packages

• pino

• winston

• roarr

• log4js

allow for log levels, easy toggling logs on and off based on environment

Logging frameworks will also (generally) support writing to more than just stdout/stderr. Winston calls these “transports” while Bunyan calls them “streams”. For example, you can configure writing to stdout, a file, and a database all at once.
