Are you interested in building a React Native app that uses GraphQL API endpoints? Then you should read this tutorial. You are going to learn how to leverage Apollo to build a client-side GraphQL application with React Native and Expo. Apollo has an entire ecosystem to build GraphQL applications. You can use it to develop client-side and server-side apps separately. Apollo has more features and support than its open-source competitors in GraphQL for JavaScript world.

Camera features power profile photos, social posts, chat attachments, video feeds, marketplace listings, delivery proof photos, and dating profiles. The modern React Native implementation needs camera permissions, microphone permissions for video, safe previews, media validation, and an upload pipeline.

AWS Amplify is a framework that lets you develop a web or mobile application quickly, by accessing the backend cloud services offered by AWS. In this article, we are going to learn how to use AWS Amplify in React Native by building a fully functional login and registration flow. This tutorial is going to take a look at one of the most important features of a mobile application – the authentication. You know the scenario. You need to store some amount of user information (credentials) for them to get back and re-use the application rather than creating a new account. Please make sure to have an AWS account before you begin this tutorial. If you don’t, please sign up for one.

Firebase Storage is commonly used in React Native apps for profile photos, posts, chat attachments, marketplace listings, restaurant images, and short videos. The upload code is simple, but production readiness depends on rules, file paths, billing, metadata, and cleanup.

In today’s article we will build a React Native Music Player, to showcase how easy it is to build a music app in React Native, that is optimized for both native iOS and Android. The project we are going to build will look and behave similar to the Spotify player, that all of us are familiar with. The main goal is to have a basic app with two screens: one with a list of predefined songs and another one with the actual music player.

In React Native WebViews enable access to any web portal in the mobile app itself. In other words, a web view allows us to open the web URLs inside the app interface. While React Native provides us with a built-it web view component, but we are going to use react-native-webview plugin in this tutorial, since it is more powerful. React Native WebView is a modern, well-supported, and cross-platform WebView for React Native.

Maps are a core part of many React Native apps: taxi booking, food delivery, real estate listings, store locators, local marketplaces, travel apps, fitness tracking, and social discovery all need some form of map display.

The Async Storage is a simple key-value pair based storage system in React Native. It is used for scenarios where you want to save the user’s data on the device itself instead of using any cloud service, such as building offline apps. According to the React Native’s official documentation:

On iOS, AsyncStorage is backed by native code that stores small values in a serialized dictionary and larger values in separate files. On Android, AsyncStorage will use either RocksDB or SQLite based on what is available.

In this tutorial, we are taking a look at how to detect and support dark mode in React Native apps. You are going to build a small demo app that sets its appearance based on the platform OS. The platform OS will have two theme modes, dark or light. By default, when the app will start, it is going to have the theme based on the platform OS but the user is going have an option to toggle between the themes.

In this tutorial, we are going to give a quick introduction to React Native hooks. Hooks in React are available since the version 16.7.0-alpha. These functions allow us to use React state and a component’s lifecycle methods in a functional component. If you are familiar with React, you know that the functional component has been called as a functional stateless component. Not any more.
