Tool overview
Overview
React Native is an open-source framework created by Meta for building high-quality mobile applications using JavaScript and React. It lets you write your UI with declarative React components while rendering truly native views on iOS and Android, so users experience smooth performance and platform-consistent behavior. With a single shared codebase, teams can dramatically reduce development time and maintenance costs compared to building separate native apps. React Native offers a rich ecosystem of community packages, powerful developer tools, and hot reloading to speed up iteration. You can integrate existing native modules written in Swift, Objective-C, Java, or Kotlin, enabling advanced
features
like camera access, push notifications, and native animations. The framework is battle-tested in production by companies such as Facebook, Instagram, Shopify, and many startups around the world. Whether you are modernizing an existing app or launching a new product, React Native provides a flexible architecture that scales from MVP to enterprise. It supports TypeScript, modern React patterns (Hooks, Context), and popular tooling like Metro, ESLint, and Jest. With strong documentation, an active community, and first-class support for both platforms, React Native is a proven choice for building cross-platform mobile apps quickly without sacrificing native look, feel, or performance.
