#DataStorage

react-native-data-storage is a data storage tool for React Native written on top of AsyncStorage.

With react-native-data-storage you can set, get, remove and check for data. You can save integers, booleans, strings, primitive objects and arrays (anything that can be represented as in the JSON format). The methods always return a promise.

##Installation

npm install react-native-data-storage --save

##Reference

set(key, value): sets a new value to the storage. get(key): gets a value in the storage. Promise is rejected if key is not found. An array of keys can be passed and an object with the values will be returned. has(key): checks whether a value has been set to the storage. Promise resolves with true of false. remove(key): removes a value from the storage. getAll(): gets all the values in the storage as an object.

##Usage

import DataStorage from 'react-native-data-storage';

Storage.set('name','John Doe')
.then((data)=>{
    return Storage.has('name');
})
.then((data)=>{
    if(data) return Storage.get('name');
    else return '';
})
.then((name)=>{
    console.log(name); //outputs 'John Doe';
    return Storage.remove('name');
})
.then((name)=>{
    console.log('Completed!');
});
