Rich text editing with DraftJS Plugins

Earlier this year Facebook open sourced its React based rich text editing framework Draft.js. At Facebook it powers status updates, comments & notes. Others used it to build editors matching Medium’s experience.

Together with a whole team of open source contributors I built a plugin architecture on top of Draft.js. In this talk I walk you through the existing plugins and show how you can build your own feature-rich text editor for the web with only a handful lines of code. 🤓

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.~~

npm Users By Downloads (git.io/npm-top)

npm users sorted by the monthly downloads of their modules, for the range May 6, 2018 until Jun 6, 2018.

A lot of people mentioned other immutable JS libraries after reading my post. I thought it would be good to make a list of available ones.

There are two types of immutable libraries: simple helpers for copying JavaScript objects, and actual persistent data structure implementations. My post generally analyzed the tradeoffs between both kinds of libraries and everything applies to the below libraries in either category.

Libraries are sorted by github popularity.
