Overview
The MongoDB Realm React Native SDK enables development of React Native applications using the JavaScript and TypeScript languages. React Native enables you to build cross-platform iOS and Android apps with a single codebase using the React framework.
Prerequisites
Before getting started, ensure your development environment meets the following prerequisites:
- React Native v0.31.0 or later. Follow the official React Native CLI Quickstart instructions to set up your environment.
- CocoaPods 1.10.1 or later (recommended for building an iOS app with React Native v.60+).
