Show HN: A local-first, real-time global canvas using CRDTs (opens in new tab)

This is a demo of a family of libraries intended to make it easy to build local-first, real-time applications for mobile, desktop and the web using CRDTs.

It currently has support for using Sqlite, PostgreSQL or a plain old record store (Hive) as data storage backend. https://github.com/cachapa/crdt

There's also a websocket sync layer that transparently handles the connection and delta changesets between participants. https://github.com/cachapa/crdt_sync
