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

Chrome 51 has some pretty wild behaviour related to console.log in service workers. Canary doesn't, and it has a load of really good service worker related stuff in devtools.

Storage

Motivation

There are 3 major types of storage is browsers up to date:

• IndexedDB. The future.
• localStorage. Limited in size and can be observed through the storage event.
• WebSQL. Dropped by the W3C but it's still very present in the wild, with notable platforms like iOS and PhoneGap.

YUI Button

Goal

To introduce a new Button component for YUI 3 that addresses the following user stories

• "I want buttons on my site to look consistent & attractive."
• "I want to be able to programmatically control buttons in my application."
• "I want to my buttons to be intelligent and interact with one another in groups."
• "I want my application to be able to dynamically generate buttons."

// A response to jashkenas's fine proposal for minimalist JavaScript classes.

// Harmony always stipulated classes as sugar, so indeed we are keeping current
// JavaScript prototype semantics, and classes would only add a syntactic form
// that can desugar to ES5. This is mostly the same assumption that Jeremy
// chose, but I've stipulated ES5 and used a few accepted ES.next extensions.

// Where I part company is on reusing the object literal. It is not the syntax
// most classy programmers expect, coming from other languages. It has annoying
// and alien overhead, namely colons and commas. For JS community members who
