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.

The app icon is one of the first production assets you should replace before submitting a React Native app to the Apple App Store or Google Play. It appears on the home screen, app stores, settings screens, notifications, search, and device launchers.

This guide explains how to replace icons in a React Native app with native iOS and Android projects.

In this tutorial we will build a React Native app that allows users to upload images and videos from their camera and photo library directly into a AWS S3 bucket. As AWS is the leader of cloud providers, a huge part of the React Native ecosystem is using AWS as the backend for their app. With the release of AWS Amplify, using AWS as backend for a React Native app has never been easier to implement.

An App Walkthrough Screen is a slider screen which allows the user to learn everything about the features of a mobile app when they open the application for the first time. We can implement this feature in a React Native application in multiple ways. In this React Native tutorial, we describe how we implemented the Walkthrough Screens in all of our React Native Templates so that you can speed up your app development by reusing our open source code.

Sign in with Apple is a common requirement for React Native apps that offer third-party login options such as Google, Facebook, LinkedIn, or Amazon. It also gives iOS users a privacy-friendly authentication option that works well with Firebase Authentication.

Optional imports support has been added recently in React Native.This feature requires no external library and is relatively easy to implement even with its enormous advantage to the overall code quality of your code. The major use-case of this feature is backwards compatibility which we will look right into next.

In this tutorial, we are going to learn how to send push notifications to React Native using Firebase. We are going to walk you through all the Firebase setup steps as well as the React Native code needed for sending notifications. Push notifications are an important user retention lever, so React Native developers run into implementing them with every single app they build.

“The notch” has been introduced by Apple a few years ago, with the launch of iPhone X. For iOS developers, this introduced more work on the day to day layout efforts, as it added an extra set of device types. On most devices that have a notch, regular views do not display well and they block out a considerable part of the top of the screen. Let’s see how we can avoid the notch in React Native projects, with the help of SaveAreaView, a component that’s built into the React Native core.

Deep linking lets a React Native app open directly to a specific screen from an external URL. It is useful for passwordless login links, push notifications, marketing campaigns, referral invites, order tracking, chat threads, and content shared from the web.
