Logging Module

[songz]

Goal

As a engineer, I want to be able to look at my monitoring systems to make sure nothing is broken and set up alerts. For example, if database is down for some reason, I should get alerted right away.

If a user reports an issue, I should be able to look at the logs and figure out what the issue is.

Basic Requirements

Logging module must support these features:

logger.error(....)
logger.log(...)

For now our logging module can just use console.log or console.error

Research

• Figure out which monitoring systems to use.
• Figure out if there is an existing logger (like winston) that already does this so we don't have to build our own logging system.
• Suggestion Multer

Acceptance criteria

• Must log each file name automatically using closure:
  • const log = require('./log')(__filename)
• Support log, warn, error
  • error is used for alerts.
  • warn is used for analysis.
  • log is informational and debugging
• Send a PR to change pg module to use logger module: https://github.com/garageScript/databases/pull/2/files
