Unlock the Power of Contacts in Your React Native App

In today’s digital landscape, contacts play a vital role in connecting people across various platforms. Gone are the days of bulky phonebooks; now, our smartphones store a wealth of contact information at our fingertips. As a developer, harnessing the power of contacts can elevate your React Native app to the next level.

What is React Native Contacts?

React Native Contacts is a robust module that empowers your app to fetch, update, and add new contacts seamlessly. By leveraging promises, this module ensures that tasks are completed efficiently without overwhelming the UI thread of your app.

Setting Up React Native Contacts

Getting started with React Native Contacts is a breeze, thanks to autolinking. However, you’ll need to make some minor adjustments to secure the necessary permissions for contacts.

Android: Add the following line to your AndroidManifest.xml file:

<uses-permission android:name="android.permission.READ_CONTACTS"/>

iOS: Install the required pods and add the following key to your info.plist file:

<key>NSContactsUsageDescription</key>
<string>This app needs access to your contacts in order to function properly.</string>

Accessing Contacts in a Bare React Native App

To tap into the contacts on a user’s device, simply import the contacts module and utilize the getAll promise. You’ll receive a JSON array with each object containing contact information. Presenting this data in a list is a cinch using React Native’s FlatList component.

import { Contacts } from 'eact-native-contacts';

Contacts.getAll()
 .then(contacts => {
    // Display contacts in a list using FlatList
  })
 .catch(error => {
    console.error(error);
  });

Accessing Contacts in a React Native Expo App

The process of fetching contacts in Expo is similar, with a slight variation in the received data structure. Import the module, use the getAll promise, and display the results in a list using your preferred component.

import { Contacts } from 'expo-contacts';

Contacts.getAll()
 .then(contacts => {
    // Display contacts in a list using your preferred component
  })
 .catch(error => {
    console.error(error);
  });

Unleash the Full Potential of React Native Contacts

With React Native Contacts and Expo Contacts, you can unlock a world of possibilities for your app. By mastering these powerful tools, you’ll be able to fetch and manipulate contacts with ease. Take your app to the next level by exploring additional modules and discover new ways to engage with your users.
