Synchronous storage for React Native.

Package Exports

  • sync-storage

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (sync-storage) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

SyncStorage

Synchronous storage for React Native AsyncStorage.

Build Status codecov npm version license

Get Started

Installation

yarn add sync-storage
# or
# npm i --save sync-storage

Usage

import SyncStorage from 'sync-storage';

SyncStorage.set('foo', 'bar');

const result = SyncStorage.get('foo');
console.log(result); // 'bar'

Methods Available

init()

Init prepares the SyncStorage to work synchronously, by getting all values for all keys previously saved on RN AsyncStorage. See the example:

const data = await SyncStorage.init();
console.log('AsyncStorage is ready!', data);

get(key: string)

Returns the value of key.

SyncStorage.get('foo'); // 'bar'

set(key: string, value: Any type)

It saves the value on memory and on the AsyncStorage.

SyncStorage.set('foo', 'bar');
SyncStorage.get('foo'); // 'bar'

It also returns a Promise for post verification.

SyncStorage.set('foo', 'bar')
  .then(() => {
    SyncStorage.get('foo'); // 'bar'
  })
  .catch(error => {
    console.log(error);
  });

remove(key: string)

It removes the value from the memory and from the AsyncStorage.

SyncStorage.remove('foo');

It also returns a Promise for post verification.

SyncStorage.remove('foo')
  .then(() => {
    SyncStorage.get('foo'); // undefined
  })
  .catch(error => {
    console.log(error);
  });

getAllKeys()

returns an array from all the keys.

SyncStorage.set('foo', 'bar');
SyncStorage.set('boo', 'baz');
console.log(SyncStorage.getAllKeys()) // ['foo', 'boo']
