Modbender Skill Library MCP Typescript Lsp

name: typescript-lsp description: TypeScript language server providing type checking, code intelligence, and LSP diagnostics for .ts, .tsx, .js, .jsx, .mts, .cts, .mjs, .cjs files. Use when working with TypeScript or JavaScript code that needs type checking, autocomplete, error detection, refactoring support, or code navigation.

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:

npm install -g typescript-language-server typescript

Or with yarn:

yarn global add typescript-language-server typescript

Verify installation:

typescript-language-server --version
tsc --version

Usage

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

tsc --noEmit  # Type check without generating output files

Compile TypeScript files:

tsc src/index.ts

Watch mode for continuous type checking:

tsc --watch --noEmit

Configuration

Create tsconfig.json in project root:

{
  "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
