shelf VS offix

I think you could encode a “shelf” last-write-wins CRDT into your HTML using data attributes without exploding your file size. You would need to add a data-version attribute, and if you want to support hand-editing or editing by programs that don’t understand the CRDT, a CRC32 or other parity as data-parity so your loader can tell when a user might have edited a row without updating data-version.

Shelf is really simple - the JS implementation is tiny (https://github.com/dglittle/shelf) and a walkthrough of the algorithm here: https://bartoszsypytkowski.com/shelf-crdt/amp/

It wouldn’t handle character level sync - but would let you merge documents at a rows/items/blocks level.

The CRDT I was referencing was Shelf by Greg Little. He's given a few talks about it at the braid meetups. When he first showed it off, Kevin Jahns (the Yjs author) was also there and was as impressed as I was:

The code is all here. Its tiny:

Yeah,I'm trying to implement an electron offline first app that syncs, there seems to readymade solution.

Stuff like https://github.com/aerogear/offix seem to be in the right direction of what I'm looking for but not nearly mature enough.

I don't want to pu to much effort on the app so I would like something more or less ready made, preferably with graphql apis.

Any suggestions welcome.

I ended up with Offix and had to do optimistic cache handling, and I wrote up my experiences in a GitHub ticket on their repo with code as guidance for others. https://github.com/aerogear/offix/issues/715
