react-native-key-value-store

A wrapper for React-Native AsyncStorage

Installation

npm i --save react-native-key-value-store

Basic Usage

import Storage from 'react-native-key-value-store';

let value = await Storage.get('foo', 'default value');
console.log(value); // should be default value if foo hasn't already been set

await Storage.set('foo', 'bar');

value = await Storage.get('foo');
console.log(value); // should be 'bar' as it has been set

All methods on the KeyValueStore are async and therefore return promises.

Methods

get(key, defaultValue)

This will get a value based on the key provided. You can also set a default value in case the key does not exist in the store.

set(key, value)

This will set a value based for the key provided.

merge(key, value)

This will merge a value into the existing value in storage

remove(key)

This will delete the key from the store.

keys()

This will return an array of all keys in the store.

Creating Namespaced Stores

The default key value store has a namespace of @Default

You can create your own key value stores with different namespaces

import { KeyValueStore } from 'react-native-key-value-store';

const appStore = new KeyValueStore('@App');

This will allow you to isolate different key/values, and will also affect the return value from keys() method, as it will check the namespace.
