Adding the JSONStore SDK to your React Native app

The JSONStore SDK for React Native is available as a React Native module from npm.

Getting started with a new React Native project

  1. Create a new React Native project.
     react-native init MyReactApp
  2. Add the MobileFirst SDK to your app.
     cd MyReactApp
     npm install react-native-ibm-mobilefirst-jsonstore --save
  3. Link all native dependencies to your app.
    react-native link

Adding data to a JSONStore collection

Inside your App.js you need to import the following packages:

import { JSONStoreCollection, WLJSONStore } from 'react-native-ibm-mobilefirst-jsonstore';

There are three steps for adding data to a JSONStore collection:

  1. Creating a new collection, you can create a new collection by calling the JSONStoreCollection constructor as shown below:.
     var favourites = new JSONStoreCollection('favourites');
  2. Opening a collection, you won’t be able to do anything with a newly created collection unless you open it. To open the collection, call WLJSONStore’s openCollections API. See the sample code below.
    WLJSONStore.openCollections(['favourites']).then(data => { console.log(data); }).catch(err =>{ console.log(err); });
  3. Adding data to collection, after you have opened a collection, start data transactions inwards or outwards. You can add data to a open collection using the following API.
     var favCollection = new JSONStoreCollection('favourites');
     .then(data => {
     	console.log("Succesfully added data to collection!"));
     .catch(err => {
     	console.log("Error while adding data to collection. Reason : " + err);
