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.

;;;; a utility to help with a datomic-datascript roundtrip process involving:
;;; 1. export some data from a datomic database and transact into a datascript instance.
;;; 2. perform one or more transactions against datascript.
;;; 3. transact the sum of all changes made against datascript back into datomic in a single tx

;;; this namespace contains two public functions:
;;; listen-for-changes: listen to datascript transactions and build up a record of changes

-- Optimized MYSQL schema for datomic
-- Unfortunately the bin/sql/mysql-*.sql bootstrapping files for datomic are not
-- very good, and can actually cause failures if not adjusted.
-- One symptom of this is the following error:

-- SQL Error (1071): Specified key was too long; max key length is 767 bytes.

-- Reported here: https://support.cognitect.com/entries/28462168-MySQL-Caveats
