It provides a unique solution for developers who need to leverage Node.js functionality within their mobile applications. + +### Key Features + +- **Isolated Node.js Process**: Runs Node.js as a separate thread/process within a React Native app +- **Cross-Platform Support**: Works on Android platforms +- **Background Execution**: Allows Node.js code to run in the background of mobile applications +- **Flexible Integration**: Enables using Node.js modules and capabilities not typically available in mobile environments + +### Primary Purpose + +The library solves the challenge of integrating Node.js functionality directly into React Native mobile applications. It creates a bridge that allows developers to: +- Execute Node.js code in a mobile context +- Run background services +- Utilize Node.js-specific libraries and tools within mobile apps +- Extend the capabilities of React Native beyond its standard runtime environment + +### Benefits + +- Seamless integration of Node.js and React Native +- Minimal performance overhead +- Simplified process of running complex backend logic in mobile apps +- Enhanced flexibility for developers working across web and mobile platforms + +## Getting Started, Installation, and Setup + +### Prerequisites + +- React Native 0.47.0 or higher +- Node.js installed on your system +- For Android: Android SDK and development environment +- For iOS: Xcode and CocoaPods + +### Installation + +Install the package using npm or yarn: + +```bash +npm install react-native-node +# or +yarn add react-native-node +``` + +### Setup and Configuration + +#### Android Setup + +1. Open your project's `android/build.gradle` file and ensure the build tools are compatible. +2. Link the library to your React Native project: + +```bash +react-native link react-native-node +``` + +#### iOS Setup + +1. Install CocoaPods if not already installed. +2. Link the library to your React Native project: + +```bash +react-native link react-native-node +``` + +### Quick Start + +Here's a basic example of how to use react-native-node in your project: + +```javascript +import RNNode from 'react-native-node'; + +// Start a Node.js process in the background +RNNode.start('./background'); + +// Stop the Node.js process when no longer needed +RNNode.stop(); +``` + +### Development and Build + +#### Development + +To run the project in development mode: + +```bash +# For React Native +yarn start + +# Build the background Node.js process +yarn build +``` + +#### Production Build + +For a production build, follow your React Native project's standard build process for Android and iOS. + +### Troubleshooting + +- Ensure all dependencies are correctly installed +- Check that your Node.js version is compatible with the project +- Verify React Native version meets the minimum requirement (0.47.0) + +## API Reference + +### Exports + +#### `RNNode` + +The `RNNode` object provides methods for managing a Node.js runtime within a React Native application. + +##### Methods + +###### `start(args?: string[])` +Starts the Node.js runtime with optional command-line arguments. + +- **Parameters**: + - `args` (optional): An array of strings representing command-line arguments to pass to the Node.js runtime. If not an array, an empty array will be used. +- **Returns**: `void` + +**Example**: +```javascript +import RNNode from 'react-native-node'; + +// Start Node.js with no arguments +RNNode.start(); + +// Start Node.js with specific arguments +RNNode.start(['-e', 'console.log("Hello from Node.js")']); +``` + +###### `stop()` +Stops the Node.js runtime. + +- **Parameters**: None +- **Returns**: `void` + +**Example**: +```javascript +import RNNode from 'react-native-node'; + +RNNode.stop(); +``` + +#### Default Export + +The library also exports `RNNode` as the default export, which can be imported directly: + +```javascript +import RNNode from 'react-native-node'; +``` + +## Technologies Used + +### Programming Languages +- JavaScript +- Node.js + +### Frameworks and Libraries +- React Native +- Cheerio +- Noderify + +### Build and Development Tools +- Babel +- ESLint +- Yarn +- npm + +### Platform-Specific Technologies +- Android (Android SDK, Java) + +### Key Dependencies +- mkdirp (directory creation utility) +- path (file path utilities) +- tar (file archiving) +- yargs (command-line argument parsing) + +### Development Environment +- React Native CLI +- Gradle (for Android build) + +### Compatibility +- Supports React Native 0.47.0 and above + +## Additional Notes + +### Deprecation Notice + +This library is officially deprecated. The recommended alternative is [Node.js Mobile](https://code.janea.systems.com/nodejs-mobile/) by Janea Systems, which offers similar functionality with broader support. + +### Debugging and Logging + +When troubleshooting, use `adb logcat` with specific tags to gain insights into the Node.js process: + +```bash +adb logcat *:S nodejs:V ReactNative:V ReactNativeJS:V +``` + +Key logging tags include: +- `RNNodeThread`: Process start, termination, and error information +- `RNNodeService`: Debugging for tar/untar and Node binary preparation +- `RNNode`: General library-related logs + +### Technical Limitations + +#### Platform Support +- **Android**: Fully supported with Node.js v7.1.0 +- **iOS**: Currently unsupported due to Apple's restrictions on Just-In-Time compilation + +#### Native Package Compatibility +- Native package support is theoretical and depends on individual library implementations +- Most packages without Android-specific native bindings should work +- For complex native packages, compiling directly on an Android device using Termux is recommended + +### Security Considerations + +The library includes a prebuilt Node.js binary (`bin_node_v710`) compiled using the NodeBase approach. For enhanced security, consider: +- Reviewing the prebuilt binary +- Compiling the Node.js binary yourself if you have specific security requirements + +### Project Origin + +This library was originally developed to support the [Scuttlebutt](https://www.scuttlebutt.nz/) ecosystem on mobile platforms, specifically for the [mmmmm mobile app](https://github.com/staltz/mmmmm-mobile). + +## Contributing + +We welcome contributions to the project!
