## What it does

The skill guides TypeScript configuration for Lynx applications. It sets up `tsconfig.json` for Rspeedy SWC transpilation by enabling `isolatedModules`, setting `jsxImportSource` to `@lynx-js/react`, and referencing `@rspeedy/core/client` in `src/rspeedy-env.d.ts`.

It provides module augmentation patterns for `@lynx-js/types` and `@lynx-js/react`. You get typing setups for `GlobalProps`, `InitData` in `useInitData()`, `NativeModules`, and custom tags under `IntrinsicElements`. It also covers typed event handlers like `TouchEvent` instead of `any`, alongside multithreading hooks such as `useMainThreadRef` and `runOnMainThread`.

Lynx type checking fails without `@lynx-js/types`, making that package a prerequisite.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add lynx-community/skills --skill lynx-typescript -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/lynx-typescript/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/lynx-typescript/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add lynx-community/skills --skill lynx-typescript -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/lynx-typescript/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add lynx-community/skills --skill lynx-typescript -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/lynx-typescript/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install lynx-community/skills lynx-typescript
```

2. **Manually: put the files in place**
- File: `.github/skills/lynx-typescript/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add lynx-community/skills --skill lynx-typescript -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/lynx-community/skills --path skills/lynx-typescript
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/lynx-typescript/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add lynx-community/skills --skill lynx-typescript -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/lynx-community/skills/tree/HEAD/skills/lynx-typescript/SKILL.md

## When to use it
- configure tsconfig.json for Rspeedy and ReactLynx
- declare custom native component types in IntrinsicElements
- extend lynx.__globalProps and InitData types
- type touch events without using any

## Example prompts
- Configure tsconfig.json for a ReactLynx project using Rspeedy
- How do I add custom properties to lynx.__globalProps in TypeScript?
- Type a bindtap event handler using TouchEvent from @lynx-js/types

# TypeScript @ Lynx

This Skill summarizes common TypeScript issues and their solutions in Lynx development, mainly covering environment configuration, type extending, event handling, components, and ReactLynx advanced usages.

## 1. Configuration (Environment Configuration)

### 1.1 `tsconfig.json` Configuration

Rspeedy reads the `tsconfig.json` in the root directory by default. Since Rspeedy uses SWC for transpilation, it is recommended to enable the `isolatedModules` option to avoid cross-file type reference errors.

```json title="tsconfig.json"
{
  "compilerOptions": {
    "isolatedModules": true,
    "paths": {
      "@/*": ["./src/*"]
    }
  }
}
```

### 1.2 Type Packages Installation

Ensure the correct type packages are installed. **@lynx-js/types** is the core type package for Lynx.

- **ReactLynx**: Install `@lynx-js/types` and `@lynx-js/react`.

### 1.3 Type Declaration File `rspeedy-env.d.ts`

To allow TypeScript to recognize Rspeedy's built-in features (such as CSS Modules, static resource imports), you need to create a `src/rspeedy-env.d.ts` file in the project:

```typescript title="src/rspeedy-env.d.ts"
/// <reference types="@rspeedy/core/client" />
```

*(Note: The actual package might depend on your Rspeedy setup, typically `@rspeedy/core` or similar for open source)*

### 1.4 ReactLynx JSX Configuration

For ReactLynx projects, you need to configure `jsxImportSource` as `@lynx-js/react` in `tsconfig.json` to ensure JSX is compiled correctly and gets type support.

```json title="tsconfig.json"
{
  "compilerOptions": {
    "jsx": "react-jsx",
    "jsxImportSource": "@lynx-js/react"
  }
}
```

## 2. Extending Lynx Types

Lynx provides default type definitions, but you usually need to extend them to suit business needs.

### 2.1 GlobalProps

Extend the type of `lynx.__globalProps`:

```typescript title="src/global-props.d.ts"
declare module '@lynx-js/types' {
  interface GlobalProps {
    appTheme: string;
    title: string;
    // Add other custom global properties
  }
}
export {};
```
This way, there will be type hints when using `lynx.__globalProps.appTheme`.

### 2.2 InitData

Extend the return value type of the ReactLynx Hook `useInitData()`:

```typescript title="src/init-data.d.ts"
declare module '@lynx-js/react' {
  interface InitData {
    userInfo: {
      name: string;
````
