Key/value Storage Library For React Native

An extremely fast, small mobile key-value key/value storage library for React Native. ~30x faster than AsyncStorage!

Features:

Get and set strings, booleans and numbers
Fully synchronous calls, no async/await, no Promises, no Bridge.
High performance because everything is written in C++ (even the JS functions have C++ bodies!)
~30x faster than AsyncStorage
Uses JSI instead of the “old” Bridge

1. Install and import the library.

# NPM
$ npm i react-native-mmkv

import { MMKV } from 'react-native-mmkv';

2. Set & get storage.

// set
MMKV.set('site.name', 'VueScript');
MMKV.set('is-vue', true);

// get
const sitename = MMKV.getString('site.name')
const isVue = MMKV.getBoolean('is-vue')

3. Get all keys.

const keys = MMKV.getAllKeys()

4. Delete an entry.

MMKV.delete('site.name')
