Obvious breaking changes

See release 10.0.0-alpha.0 for a full list.

h -> createElement
VNode.nodeName -> VNode.type
VNode.attributes -> VNode.props
VNode.children -> VNode.props.children

This was built and written in 2016. While the project didn't gain much traction, the intro post is kept here for posterity.

Building realtime applications is hard.

A scalable solution to this problem involves many cumbersome steps:

Hooking into replication logs of the database servers, or writing custom data invalidating logic for realtime UI components.
Adding messaging infrastructure (e.g. RabbitMQ) to your project.
Writing sophisticated routing logic to avoid broadcasting every message to every web server.
Reimplementing database functionality in the backend if your app requires realtime computation (e.g. realtime leaderboards).
