React Native Expo Articles

This free, hands-on React Native tutorial teaches React Native Gesture Handler using the latest 2026 APIs and best practices. This article explains how to use React Native Gesture Handler with Expo (and bare React Native) to build smooth and responsive touch interactions. It covers installation, configuration, and practical examples of common gestures such as tap and pan to help you create better user experiences in React Native apps. Whether you're new to React Native gestures and animations or migrating from older APIs, this tutorial helps you confidently build responsive, interactive, and performant mobile UI using React Native in 2026.

This article explains how to use React Native Reanimated with Expo to create smooth and performant animations. It covers the core concepts, setup, and practical animation examples that help improve UI responsiveness and user experience in React Native apps.

This article demonstrates how to fetch data in an Expo (React Native) application using both the built-in Fetch API and Axios. It covers basic data fetching, passing query parameters, and making authenticated requests with headers. Practical examples are provided for each approach to help developers understand when and how to use Fetch or Axios when working with external APIs.

Learn how to set up and use React Navigation v7 in Expo, including bottom tab navigation and @expo/vector-icons. Run examples on physical devices and Expo Go, and understand environment differences with Expo Snack.

React Navigation with Expo Router provides a modern and efficient way to handle navigation in React Native apps. By combining the robust capabilities of React Navigation with the file-based, convention-driven system of Expo Router, developers can quickly create both simple and complex navigation structures. Common patterns such as stack navigation for hierarchical screen flows, bottom tab navigation for switching between main sections, and drawer navigation for hidden menu layouts can all be implemented easily. With Expo Router, routes are automatically mapped from your file structure, supporting dynamic routes and nested layouts, while still leveraging React Navigation under the hood. This approach reduces boilerplate, speeds up development, and makes navigation logic more organized, allowing developers to build scalable and maintainable React Native applications efficiently.

This article explains how to schedule local notifications in an Expo app, including how to handle permissions, manage iOS and Android differences, and ensure notifications appear even when the app is in the background or foreground. You'll learn step-by-step examples for letting users pick a notification time, handling denied permissions, and preparing your app for real-device testing.

This article walks through setting up remote notifications in Expo, covering both the Expo Push Notification service and direct Firebase Cloud Messaging (FCM). It explains why configuring Firebase directly can simplify testing and avoid common pitfalls, especially with the stricter FCM HTTP v1 API that requires service account credentials and OAuth tokens. You'll learn how to retrieve both Expo push tokens and FCM device tokens, test each system separately, and troubleshoot common issues such as token mismatches or Android package name conflicts. The article also highlights why the newer FCM setup is more secure and feature-rich compared to the legacy API.
