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.~~

Add a new platform in the UnifiedPush Server

This is simple checklist for those who would like to add a new Push Platform support to UPS (like Blackberry hint for the community hint).

Adapt the Model

Start by updating the Variant Enum class by adding your platform
Create a subclass of the Variant base class , add any properties that are specific to this platform (like API keys, secrets etc ...)

Usage

npm run setup
npm run server

tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

	self.addEventListener('fetch', event => {
	const cached = caches.match(event.request);
	const fetched = fetch(event.request);
	const fetchedCopy = fetched.then(resp => resp.clone());

	// Call respondWith() with whatever we get first.
	// If the fetch fails (e.g disconnected), wait for the cache.
	// If there’s nothing in cache, wait for the fetch.
	// If neither yields a response, return a 404.
