The 0.13.0 improvements to React Components are often framed as "es6 classes" but being able to use the new class syntax isn't really the big change. The main thing of note in 0.13 is that React Components are no longer special objects that need to be created using a specific method (createClass()). One of the benefits of this change is that you can use the es6 class syntax, but also tons of other patterns work as well!

Below are a few examples creating React components that all work as expected using a bunch of JS object creation patterns (https://github.com/getify/You-Dont-Know-JS/blob/master/this%20&%20object%20prototypes/ch4.md#mixins). All of the examples are of stateful components, and so need to delegate to React.Component for setState(), but if you have stateless components each patterns tends to get even simpler. The one major caveat with react components is that you need to assign props and context to the component instance otherwise the component will be static. The reason is

The issue:

..mobile browsers will wait approximately 300ms from the time that you tap the button to fire the click event. The reason for this is that the browser is waiting to see if you are actually performing a double tap.

(from a new defunct https://developers.google.com/mobile/articles/fast_buttons article)

touch-action CSS property can be used to disable this behaviour.

touch-action: manipulation The user agent may consider touches that begin on the element only for the purposes of scrolling and continuous zooming. Any additional behaviors supported by auto are out of scope for this specification.

Why we dropped Lerna from PouchDB

We dropped Lerna from our monorepo architecture in PouchDB 6.0.0. I got a question about this from @reconbot, so I thought I'd explain our reasoning.

First off, I don't want this post to be read as "Lerna sucks, don't use Lerna." We started out using Lerna, but eventually outgrew it because we wrote our own custom thing. Lerna is still a great idea if you're getting started with monorepos (monorepi?).
