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']
