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.

React Native is one of the leading frameworks for developing cross-platform applications with ease. You can set up and get an app running in a couple of minutes due to its simple approach. Following React’s state-based rendering approach, applications built with React Native are very robust. In this article, we will be implementing React Native biometrics authentication with Expo, by leveraging expo-local-authentication open-source library. Let’s get started.

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.

Video compression is one of the easiest ways to reduce upload time, storage cost, and feed latency in a React Native app. It matters for social networks, chat apps, marketplace listings, short video apps, fitness apps, and any product that lets users upload media from the camera roll.

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.

You might have seen Google Maps in almost all the apps these days. Some mobile apps are displaying their outlet locations, track users (like Uber), showing nearby places, etc. So, it shows the importance of maps support in mobile apps. Today, we are going to integrate Google Maps in a React Native app step by step, using the popular React Native Maps package.

React Native tooling has changed. Older lists often recommended Flipper, Nuclide, standalone React Native Debugger, or remote Chrome debugging as the default workflow. Modern React Native apps should start with React Native DevTools, Metro, and the native tools that ship with Xcode and Android Studio.

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.
