Welcome — this short guide helps you quickly find and fix networking issues in React Native apps. You'll get practical steps to inspect requests with Flipper, add logging and error handling with Axios interceptors, use the native Fetch API for troubleshooting, run simple tests, and deploy fixes via Expo's OTA updates.

This short guide helps you make React Native apps run smoother on older Android phones (API 21–28) by applying practical, beginner-friendly optimizations. Follow the steps to enable Hermes, shrink and harden your APK with ProGuard, optimize list and image rendering, and deploy fixes quickly with EAS OTA updates so users on low-end devices get a noticeably better experience.

Upgrading a React Native app doesn't have to be stressful. This concise, step-by-step guide walks you through upgrading to React Native with Expo SDK, addressing common breaking changes, dependency conflicts, platform configuration updates, testing strategies, and OTA deployment. Follow the practical commands and troubleshooting tips to get your app building and running reliably on the latest SDKs.

This article shows how to connect a React Native app to REST APIs using Axios (with optional Fetch), focusing on practical, TypeScript-friendly examples. You’ll learn how to perform GET and POST requests, add robust error handling, write simple tests, and deploy OTA updates with Expo EAS. Examples target React Native 0.75.4 and Expo SDK 51 but are applicable to most modern projects — by the end you’ll have a small posts app that fetches, creates, and handles API-driven data reliably.

Memory issues can silently erode app performance, battery life, and user satisfaction. This concise guide walks you through practical, repeatable steps to identify, debug, and fix common memory leaks in React Native apps—using Flipper, Hermes profiling, and React Developer Tools—so you can find the root cause and apply safe, testable fixes.

React Native lists can become sluggish as data grows — this short guide shows practical, TypeScript-friendly techniques to get smooth scrolling back. Using Expo (SDK 51) and React Native 0.75.4 as a baseline, you'll learn how to tune FlatList props, memoize item rendering, fetch data efficiently with Axios, and deploy fixes via EAS OTA updates. Follow the step-by-step examples and code snippets to improve rendering performance on both iOS and Android.

Continuous Integration for React Native Apps with Fastlane and GitHub Actions

Building a React Native app is fun, but manually testing, building, and deploying every change can slow you down. Continuous integration (CI) automates these tasks, letting you focus on creating awesome features. In this beginner-friendly guide, we’ll set up a CI pipeline for your React Native app using Fastlane, GitHub Actions, and Expo Application Services (EAS) with Expo SDK 51 and React Native 0.75.4. We’ll automate builds for iOS (Xcode 16+, iOS 18 SDK) and Android (SDK 35), run tests, and deploy OTA updates and store releases. No CI experience is needed, and we’ll explain key terms along the way. For prebuilt CI setups, check out templates at Instamobile or Dopebase.
