This native RN library provides bindings for LevelDB. What makes it special is that it uses RN's JSI to avoid the JSON (de)serialization that's usually required when going over the bridge.
In my tests our library performed 2x (iPhone XS) to 7x faster (Samsung J5) than either AsyncStorage or react-native-sqlite-storage, as both depend on the RN's bridge.
We are going to be using this in production long term. Looking forward to your comments and happy to help if you are planning to use this.
