Installation

# install adapter
npm i @nano-sql/adapter-react-native --save
# link async storage
react-native link @react-native-community/async-storage

Usage

import { NativeStorage } from "@nano-sql/adapter-react-native";
import { nSQL } from "@nano-sql/core";

nSQL().createDatabase({
    id: "my_db",
    mode: new NativeStorage(true), // true to enable index cache, leave blank otherwise
    tables: [...]
}).then(...)

API

The NativeStorage class accepts one optional argument that is used to enable or disable index caching.

If true is passed in, table indexes will be stored in javascript memory to increase write performance and range query performance. If false or nothing is passed in, write performance and range queries will be slower but indexes will only be loaded into memory as they are needed, then cleared from memory.
