What is react-native-codegen?

The react-native-codegen package is a tool used in the React Native ecosystem to generate native code for JavaScript components and modules. It helps in creating type-safe interfaces between JavaScript and native code, ensuring that the data passed between them is correctly typed and validated.

What are react-native-codegen's main functionalities?

Generating Native Modules

This feature allows you to define a native module in a JSON format, which react-native-codegen will then use to generate the corresponding native code. This ensures type safety and consistency between JavaScript and native code.

```json
{
  "name": "MyModule",
  "type": "module",
  "methods": {
    "myMethod": {
      "type": "function",
      "params": [
        { "name": "param1", "type": "string" },
        { "name": "param2", "type": "number" }
      ],
      "returnType": "void"
    }
  }
}
```

Generating Native Components

This feature allows you to define a native component in a JSON format, which react-native-codegen will then use to generate the corresponding native code. This ensures that the component's props are correctly typed and validated.

```json
{
  "name": "MyComponent",
  "type": "component",
  "props": {
    "title": { "type": "string" },
    "count": { "type": "number" }
  }
}
```

Generating Event Emitters

This feature allows you to define an event emitter in a JSON format, which react-native-codegen will then use to generate the corresponding native code. This ensures that the events and their data are correctly typed and validated.

```json
{
  "name": "MyEventEmitter",
  "type": "eventEmitter",
  "events": {
    "onEvent": {
      "type": "function",
      "params": [
        { "name": "eventData", "type": "object" }
      ]
    }
  }
}
```

Other packages similar to react-native-codegen

    react-native-create-library

    The react-native-create-library package is used to create a new native module library for React Native. It provides a boilerplate for creating native modules but does not offer the same level of type safety and code generation as react-native-codegen.

    react-native-builder-bob

    The react-native-builder-bob package is a CLI tool for creating and building React Native libraries. It focuses on setting up the project structure and build configuration but does not provide code generation capabilities like react-native-codegen.
