Local Storage with React Native

Asked

I’m creating an application that needs to store some data locally. These are simple data such as a "Route" path for HTTP request, or a field with a "time" that will be used for the application to do an action.

Knowing this can tell me how I can save this data?

As a reference would be something like having a preference file on android or Sqlite database where I would save a lot of basic data that are used as configuration of the application.

I did not understand the application of Assyncstorage because among the data I need to save is an "array".

You could help me with that question?

  • If you need something relational, and you don’t want to use Asyncstorage you can try Realmdb

You can use Asyncstorage to store all data types locally.

For basic variables you can simply insert in arrows to store

var someText = "abc";
await AsyncStorage.setItem('someTextName', someText);

to fetch the information you can use getItem

var someText = await AsyncStorage.getItem('someTextName');

For cases where you need to store objects or arrays you can use JSON to store as follows:

var someArray = ["abc", "def", "ghi"];
await AsyncStorage.setItem('someArrayName', JSON.stringify(someArray));

to fetch the information just parse back to the object, thus:

var someArrayString = await AsyncStorage.getItem('someArrayName');
var someArray = JSON.parse(someArrayString );
