Appropriate Local Storage for Ionic 3

You can easily use Ionic storage module here. You just need to install SQLite plugin. Details are in the above doc. Then you can use it natively on iOS and Android too without any issue.

Usage:

 // set a key/value
  storage.set('name', 'Max');

  // Or to get a key/value pair
  storage.get('age').then((val) => {
    console.log('Your age is', val);
  });
