gun-react-native-sqlite

A Gun <> SQLite Adapter for React Native apps to enable long-term storage for Gun data.

This is an updated fork of the original package by sjones6.

Installation

npm install gun-react-native-sqlite --save or yarn add gun-react-native-sqlite.

This module depends on react-native-sqlite-storage for SQLite bindings. Follow instructions here to ensure that SQLite is installed and accessible.

Run

import Gun from './gun-rn/index';
import GunSQLite from './gun-react-native-sqlite/index';
const adapter = GunSQLite.bootstrap(Gun);

const gun = new Gun({

    // Defaults
    sqlite: {
        database_name: "GunDB.db",
        database_location: "default", // for concerns about location on iOS, see [here](https://github.com/andpor/react-native-sqlite-storage#opening-a-database)
        onOpen: () => {},
        onErr: err => {},
        onReady: err => {} // don't attempt to read/write from Gun until this has been called unless you like to live dangerously
    }
})

Cleaning Up Old Data

Depending on your application, your graph data can grow in size and has the potential to overwhelm your DB storage size.

The adapter provides a hook to clear out data that is older than a certain time:

import GunSQLite from './gun-react-native-sqlite/index';
const adapter = GunSQLite.bootstrap(Gun);


// Do a whole bunch of stuff, load and store data, etc, etc

// Clear out anything older than 24 hrs from local storage
adapter.clean(Date.now() - (1000 * 60 * 60 * 24), err => {
    if (!err) {
        console.log("All cleaned up!");
    }
});

Assuming that you're storing this data somewhere else (like, on a server somewhere), this does not delete the data from Gun permanently; it just removes it from local storage.

TODO

  • Support createFromLocation option
  • Android testing/support
  • Performance profiling

Compatibility

This has only been testing with iOS, but it should be compatible with Android. If using Android, please report any issues; even better, submit a PR.
