## 概述（中文）

TypeScript 语言服务器为 .ts、.tsx、.js、.jsx、.mts、.cts、.mjs、.cjs 文件提供类型检查、代码智能和 LSP 诊断。在处理需要类型检查、自动完成、错误检测、重构支持或代码导航的 TypeScript 或 JavaScript 代码时使用。

## 原文

# TypeScript LSP

TypeScript/JavaScript language server integration providing comprehensive code intelligence through typescript-language-server.

## Capabilities

- **Type checking**: Static analysis of TypeScript and JavaScript types
- **Code intelligence**: Autocomplete, go-to-definition, find references, rename symbols
- **Error detection**: Real-time diagnostics for type errors, syntax issues, and semantic problems
- **Refactoring**: Extract function/variable, organize imports, quick fixes
- **Supported extensions**: `.ts`, `.tsx`, `.js`, `.jsx`, `.mts`, `.cts`, `.mjs`, `.cjs`

## Installation

Install TypeScript language server and TypeScript compiler:

```bash
npm install -g typescript-language-server typescript
```

Or with yarn:
```bash
yarn global add typescript-language-server typescript
```

Verify installation:
```bash
typescript-language-server --version
tsc --version
```

## Usage

The language server runs automatically in LSP-compatible editors. For manual type checking:

```bash
tsc --noEmit  # Type check without generating output files
```

Compile TypeScript files:

```bash
tsc src/index.ts
```

Watch mode for continuous type checking:

```bash
tsc --watch --noEmit
```

## Configuration

Create `tsconfig.json` in project root:

```json
{
  "compilerOptions": {
    "target": "ES2020",
    "module": "ESNext",
    "strict": true,
    "esModuleInterop": true,
    "skipLibCheck": true,
    "forceConsistentCasingInFileNames": true,
    "resolveJsonModule": true,
    "moduleResolution": "node"
  },
  "include": ["src/**/*"],
  "exclude": ["node_modules", "dist"]
}
```

## Integration Pattern

When editing TypeScript/JavaScript code:
1. Run `tsc --noEmit` after significant changes
2. Address type errors before committing
3. Use `tsc --watch` during active development
4. Leverage quick fixes for common issues

## Common Flags

- `--noEmit`: Type check only, no output files
- `--strict`: Enable all strict type checking options
- `--watch`: Watch mode for continuous compilation
- `--project <path>`: Specify tsconfig.json location
- `--pretty`: Stylize errors and messages
