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.

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.

React Native has become one of the most popular frameworks for building cross-platform mobile applications. If you’re a Windows user looking to start your React Native development journey, this comprehensive guide will walk you through every step of the installation process.
Our premium app templates are fully functional starter source codes, to help software developers and tech entrepreneurs make their mobile apps more quickly and at a fraction of the cost.

React Native developers are often in the situation of releasing their React Native apps to the Google Play Store so that Android users can download them. In this tutorial, we are going to learn how to generate a React Native Release Build APK for Android, using both React Native CLI and Android Studio IDE. At Instamobile, we launched all of our React Native Templates to production (Google Play Store demos), so we are familiar with the process as well as the errors that might show up when generating a React Native Release Build APK for Android. We are documenting our learnings in this React Native tutorial, to help mobile developers ship their Android apps to production more quickly.

Vibe coding is a new, informal term for writing software by talking to AI tools instead of typing code. In practice, a person simply describes a task in plain English (or another natural language) to a large language model (LLM) that’s been trained to write code. The AI then generates working source code to solve the task. As one summary explains, it shifts “the programmer’s role from manual coding to guiding, testing, and refining the AI-generated source code”.
