+## Codegen Config
+
+The `react-native codegen-windows` command is configured by the `codegenConfig` object in the project's `package.json` file. This `codegenConfig` object is shared by all platforms, but the relevant parts for React Native for Windows is configured as follows:
+
+| Field | Type| Description |
+|:------|:---:|:------------|
+| `type` | string | `"modules"` for Native Modules, `"components"` for Native Components, or `"all"` for both |
+| `jsSrcDir` | string | Path to the TypeScript spec input files |
+| `windows` | object | Windows-specific codegen configuration |
+
+The `windows` object is configured as follows:
+
+| Field | Type| Description |
+|:------|:---:|:------------|
+| `namespace` | string | The C++ namespace to contain the generated code |
+| `cppStringType` | string | Optional, the string type to use in C++ code, either `"std::string"` or `std::wstring`. Defaults to `"std::string"` |
+| `generators` | array | Optional, array of codegen generator strings, accepting `"modulesWindows"` for Native Modules, `"componentsWindows"` for Native Components. Defaults to `[ "modulesWindows" ]` |
+| `outputDirectory` | string | Optional, path to place the generated code. Defaults to `./codegen/` of the working directory |
+| `separateDataTypes` | boolean | Optional, specify whether to create separate files to define custom data types. Defaults to `false` |
+
+> **Note:** For more information on how to configure the `codegenConfig` object for other platforms, see the [reactnative.dev Configuring Codegen](https://reactnative.dev/docs/the-new-architecture/using-codegen#configuring-codegen) page.

 React Native for Windows supports writing native code in both C++ and C#, but there are trade-offs with each language. The choice of language can impact the compatibility, developer experience, and performance of your project. So whether you're building an app or native module, you should choose the native language that best meets your requirements.

 A common scenario for [Native Modules](native-modules.md) is to call one or more native asynchronous methods from a JS asynchronous method. However it may not be immediately obvious how to properly bridge both asynchronous worlds, which can lead to unstable, difficult to debug code.

 `JSValue` is a native, immutable invariant value type, and is meant to hold any of the commonly used JS types: `bool`s, `int`s, `double`s, `string`s, arrays, and objects.

 Community native modules are usually distributed as npm packages. To understand more about npm packages you may find [this guide](https://docs.npmjs.com/packages-and-modules/contributing-packages-to-the-registry) useful.
 
 Consuming native modules requires updating your app's native build files to depend on the module's native build files, called "linking". Many modules support "autolinking", where these updates are done automatically when running the [run-windows command](run-windows-cli.md). Others may require you to link the module manually.

 If you've worked with React Native, you may be familiar with the concept of Native Modules, which allow JavaScript and platform-native code to communicate over the React Native "bridge", which handles cross-platform serialization via JSON.
 
 TurboModules are the next iteration of Native Modules that provide a few extra benefits, in particular these modules use JSI, a JavaScript interface for native code, which allows for more efficient communication between native and JavaScript code than the bridge.
