Local first is the first software trend in a long time that has gotten me really excited. The aspect of co-located data and logic is what's most interesting for me for two reasons:

1. Easier to develop - Sync layer handles all the tricky stuff, no need for translation layer between server and client.

2. Better user experience - Immediate UI feedback, no network dependency etc.

I suspect there will be a major tide shift within the next year or two when a local first framework with the developer experience similar to Nuxt or Next comes about. The Rails of local first.

I can't recommend enough the localfirst.fm podcast which has been a great introduction to the people and projects in the space: https://www.localfirst.fm/
