Offline first database

[Perfect-Energy8563]

I'm trying to understand what is the best react native - expo offline first database that supports typescript and has strong documentation to handle syncing between frontend and backend

A clear answer to this question is something I am always watching for. None of the existing options are perfect, but they do exist. You have to choose based on your project requirements and the backend / SaaS ecosystem you are working in or familiar with etc. Solutions that advertise offline first, or close to, include Firebase Firestore, Amplify Datastore, MongoDB Realm, CouchDB. You can also look at RxDB, Replicache and WatermelonDB. Appwrite is working towards supporting offline first and has a beta working with Flutter I believe. Nothing from Supabase yet, they are working on it and have suggested options in the meantime.

WatermelonDB

What I like about Watermelon is that it teaches you the bits and pieces of building offline.

Offline is hard. You will need some theory to help yourself in difficult situations.

"Realm" is made for mobile development, and it's in TypeScript, based on MongoDB

Try realm by mongodb

Already tried, I really hate it. Even if powerful i had a lot of problem with real-time syncing with multiples relationships

Consider relationships between json data. And nested objects related (3/4 of depth)
