Welcome to react-native-tscodegen (beta)!

This library enable people to write react-native Turbo Module in TypeScript, and generate native code in C++, Objective C++ and Java!

Target react-native version

0.70.1

Authoring a Turbo Module

At this moment, the new Turbo Module API is not published by Facebook,
you need npm package react-native-tscodegen-types to access these new APIs.
Here is an example of a very simple Turbo Module TypeScript file: ./src/turboModule.ts.

``typescript
import { TurboModule, TurboModuleRegistry } from 'react-native-tscodegen-types';

export interface Spec extends TurboModule {
getHello(name: string): string;
}

// tslint:disable-next-line
export default (TurboModuleRegistry.getEnforcing('SampleTurboModule') as Spec);
`

Code generation

In order to do code generation, you need an extra JSON file for this TypeScript file.
They are one-to-one mapping for now,
if you have multiple TypeScript files, you need multiple JSON files
This will be improved in the future.

Name the following file as react-native-tscodegen.json

`json
{
"libraryName": "PlaygroundModule",
"outputDirectory": "./lib/cpp-generated",
"moduleSpecName": "PlaygroundModuleSpec",
"generators": [
"descriptors",
"events",
"props",
"tests",
"shadow-nodes",
"modulesAndroid",
"modulesCxx",
"modulesIOS"
],
"inputFile": "./src/turboModule.ts"
}
`

And add this script to your package.json

`json
{
"scripts": {
"codegen": "react-native-tscodegen ./react-native-tscodegen.json"
}
}
`

After running npm run codegen, you will see files get generated in ./lib/cpp-generated`.

Building C++ files

You are expected to use react-native-windows for implementing turbo modules in C++.
