React Native Settings module for both Android & iOS.
| In my country (México), software developers are poorly paid, so I have had to look for another job to earn a living and I cannot dedicate more time to maintaining this and other repositories that over the years have never generated any money for me. If anyone is interested in maintaining this repository, I'd be happy to transfer it to them, along with the associated npm package. |

If this library has helped you, don't forget to give it a star 🌟
v2.1.0 works with Gradle 4.10.x, the default in React Native 0.58. If you are using Gradle 3.x please use react-native-cross-settings 1.0.2
yarn add react-native-cross-settings
react-native link react-native-cross-settingsimport Settings from 'react-native-cross-settings';
// Set a listener. It will be called for *each* value that has changed.
const watchId = Settings.watchKeys('strvar', () => {
console.log('strvar changed.');
});
// If you never saved a value in "strvar", this is undefined.
console.log('restored setting:', Settings.get('strvar'));
// => undefined
// Store a value (only string, number, or boolean)
Settings.set({ strvar: 'First setting' });
console.log('new setting:', Settings.get('strvar'));
// => "First setting"
// You cann't remove a value, but you can set it to null.
// Next time your App start, the value will be undefined.
Settings.set({ strvar: null });
console.log('new setting:', Settings.get('strvar'));
// => null
// Store a new value, this will be preserved across sessions.
Settings.set({ strvar: 'final value' });
// => Don't forget to remove the listener
Settings.clearWatch(watchId)See React Native Settings page, the API is the same.
-
get()
static get(key: string) => number | string | value | null
-
set()
static set(settings: { [key: string]: number | string | boolean | null } ) => void
-
watchKeys()
static watchKeys(keys: string | string[], callback: () => any) => number
-
clearWatch()
static clearWatch(watchId: number) => void
In Android, valid value types to store are boolean, string, and number.
If you pass null as value, the key will be removed in the next session.
If you want to save other types use the appropriate conversion:
// Storing a Date object:
Settings.set({ myDate: new Date().toJSON() })
// Retrieve
const myDate = new Date(Settings.get('myDate'))
// Storing an array
Settings.set({ myArray: JSON.stringify([1,2,3]) })
// Retrieve
const myArray = JSON.parse(Settings.get('myArray') || '[]')I'm a full-stack developer with more than 20 year of experience and I try to share most of my work for free and help others, but this takes a significant amount of time and effort so, if you like my work, please consider...
Of course, feedback, PRs, and stars are also welcome 🙃
