Logging levels

[adamziel]

The amount of log messages is too large and reduces the usefulness of the logged information. Let's find a solution that supports:

• Different logging level (at least debug, info, warn, error)
• Custom module labels (like PHP, ServiceWorker, etc.)
• Filtering the output by level and module

There's an NPM library called debug that's popular.

debug - A tiny JavaScript debugging utility modelled after Node.js core's debugging technique. Works in Node.js and web browsers

Maybe has too many features, like assigning unique color to each namespace.

Another NPM library is called log. It's more minimal, and has logging levels as you described.

log - Universal logging utility

This was a super annoying issue when I was initially working on the service worker, but I never had that problem ever since. The default console levels like warn() or debug() seem to be good enough. If this is ever a problem, let's reopen this issue.
