Stuff I wish I'd known sooner about service workers

I recently had several days of extremely frustrating experiences with service workers. Here are a few things I've since learned which would have made my life much easier but which isn't particularly obvious from most of the blog posts and videos I've seen.

I'll add to this list over time – suggested additions welcome in the comments or via twitter.com/rich_harris.

Use Canary for development instead of Chrome stable

// NOTE: this adds a filename and line number to winston's output
// Example output: 'info (routes/index.js:34) GET 200 /index'

var winston = require('winston')
var path = require('path')
var PROJECT_ROOT = path.join(__dirname, '..')

var logger = new winston.logger({ ... })

// this allows winston to handle output from express' morgan middleware
