This article has been quite the inspiration for many projects and progress on this front. I think we're seeing more and more developments around CRDTs and local-first frameworks / applications.
I'm working on a few projects in this area:
- https://www.typecell.org - Notion meets Notebook-style live programming for TypeScript / React
- https://www.blocknotejs.org - a rich text editor built on TipTap / Prosemirror that supports Yjs for local-first collaboration
- https://syncedstore.org - a wrapper around Yjs for easier development
In my experience so far, some things get more complicated when building a local-first application, and some things get a lot easier. What gets easier is that once you've modeled and implemented the data-layer (which does require you to rethink / unlearn a few principles), you don't need to worry about data-fetching, errors etc. as much as in a regular "API-based" app.
Another interesting video I recommend on this topic is about Linear's "Sync Engine" which employs some of the local-first techniques as well: https://www.youtube.com/watch?v=Wo2m3jaJixU
