Fetching data from JSONStore collection

Setting up the React Native development environment

Follow the instructions provided in the React Native Gettings Started Page to set up your machine for React Native development.

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 Persistent Mobile Foundation 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
   

Fetching data from JSONStore collection

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

import { JsonStoreCollection, WLJsonStore } from 'react-native-ibm-mobilefirst-jsonstore';

There are two steps for fetching data from a JSONStore collection:

1. Opening a Collection, opening a collection allows us to interact with it.

    WLJsonStore.openCollections(['favourites']).then(data => { console.log(data); }).catch(err =>{ console.log(err); });
   

2. Fetching data from a Collection: After you have opened a collection, you can fetch all the documents using the following API.

    var favCollection = new JSONStoreCollection('favourites');
    favCollection.findAllDocuments()
    .then(data => {
    	console.log("Succesfully fetched all documents from collection!"));
    	console.log("Data: " + JSON.stringify(data));
    .catch(err => {
    	console.log("Error while fetching data from collection. Reason : " + err);
    });
