Breakpoints are still one of the fastest ways to understand a React Native bug. The tool has changed: for modern React Native apps, start with React Native DevTools instead of old remote Chrome debugging or standalone React Native Debugger workflows.

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.

Biometric authentication can make a React Native app feel faster and safer, but it should be designed as a local unlock step, not as a replacement for your account system. The device verifies the enrolled fingerprint or face; your app decides what to unlock after that verification succeeds.

Expo's expo-local-authentication package gives React Native apps access to Face ID, Touch ID, Android Biometric Prompt, and device passcode fallback.

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.

React Native WebView lets a native app display trusted web content inside a screen. It is useful for checkout, help centers, terms, OAuth pages, and embedded dashboards, but it needs clear security boundaries and loading states.

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.

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.

Offline-first React Native apps need deliberate data design. Lightweight preferences can use AsyncStorage, but serious offline workflows need structured local data, queued writes, sync conflict handling, retries, and visible user states.

Dark mode in React Native should start with system appearance APIs and a real theme model. This guide now focuses on useColorScheme, Appearance, app-level overrides, design tokens, and production checks across native and JavaScript surfaces.
