@react-native/codegen
Advanced tools
Package description
The @react-native/codegen package is a tool used in the React Native ecosystem to generate native code (Java for Android, Objective-C for iOS) from JavaScript. It is primarily used to bridge custom native modules and components in a React Native application, facilitating the communication between JavaScript and native code. This tool automates the process of creating the necessary boilerplate code for native modules, making the development process more efficient and less error-prone.
Generating Native Modules
This feature allows developers to generate the boilerplate code for native modules by specifying the platform (iOS or Android), the path to a schema file (schema.json) that describes the module, and the output directory. The schema file is a JSON file that outlines the structure and types of the native module's methods and properties.
"npx react-native codegen --platform ios/android --schemaPath ./schema.json --outputDir ./output"Generating Native Components
Similar to native modules, this feature enables the generation of boilerplate code for native components. The process involves specifying a schema file (componentSchema.json) that describes the component's properties and events, allowing for seamless integration of custom native UI components into React Native applications.
"npx react-native codegen --platform ios/android --schemaPath ./componentSchema.json --outputDir ./output"React Native Builder Bob is a tool that helps developers create React Native libraries with support for both native and JavaScript code. While it provides a streamlined process for setting up, building, and publishing libraries, it does not offer the same code generation capabilities for bridging native modules and components as @react-native/codegen.
React Native Create Bridge is a CLI tool designed to simplify the process of creating native modules and UI components for React Native. It offers a more interactive approach by prompting users for input to generate the necessary boilerplate code. However, it is not as automated or schema-driven as @react-native/codegen, requiring more manual intervention.
