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.~~

Deep Merge

Quick function to deep merge using Object.assign(). Thoughts?

    /**
     * Simple is object check.
     * @param item
     * @returns {boolean}
     */

This is no longer a bug. I'm keeping the gist for historical reasons, as it helped to get it fixed. Make sure to read the notes by the end of the post.

How to remove hide the select arrow in Firefox using `-moz-appearance:none;`

TL;DR (or, the fix)

Set -moz-appearance to none. This will "reset" the styling of the element;
Set text-indent to 0.01px. This will "push" the text a tiny bit^[1] to the right;

Slimdown

This project has moved to github.com/jbroadway/slimdown

A very basic regex-based Markdown parser. Supports the following elements (and can be extended via Slimdown::add_rule()):
