We want software to be local-first. That means we need to make it more convenient to work with complex data on clients.
Homebase React lets you plug a relational database into your React app.
- Replace Redux with something simpler and more declarative
- Gain all the benefits of relational data like a single source of truth
- Query your database with a convenient JSON query syntax
- Query your database with datalog if you need more power
- Traverse your data graph like it's one big JSON object
It is immediately more intuitive than a denormalized JSON store, and over time it will get better as we add more local-first features to it.
- Improve performance
- Document integration with backends
- Swap Datascript out for Datahike
- Immutability
- History / Change Tracking
- Persist to IndexDB
- Local-first conflict resolution for offline caching and sync between multiple devices
