TypeScript Documentation

Generate production-ready TypeScript documentation with layered architecture for multiple audiences. Supports API docs with TypeDoc, ADRs, and framework-specific patterns.

Overview

Use JSDoc annotations for inline documentation, TypeDoc for API reference generation, and ADRs for tracking design choices.

Key capabilities:

• TypeDoc configuration and API documentation generation
• JSDoc patterns for all TypeScript constructs
• ADR creation and maintenance
• Framework-specific patterns (NestJS, React, Express, Angular, Vue)
• ESLint validation rules for documentation quality
• GitHub Actions pipeline setup

When to Use

Use this skill when creating API documentation, architectural decision records, code examples, or framework-specific patterns for NestJS, Express, React, Angular, or Vue.

Quick Reference

JSDoc Tags

Instructions

1. Configure TypeDoc

npm install --save-dev typedoc typedoc-plugin-markdown

{
  "entryPoints": ["src/index.ts"],
  "out": "docs/api",
  "theme": "markdown",
  "excludePrivate": true,
  "readme": "README.md"
}

2. Add JSDoc Comments

/**
 * Service for managing user authentication
 *
 * @remarks
 * Handles JWT-based authentication with bcrypt password hashing.
 *
 * @example
 * ```typescript
 * const authService = new AuthService(config);
 * const token = await authService.login(email, password);
 * ```
 *
 * @security
 * - Passwords hashed with bcrypt (cost factor 12)
 * - JWT tokens signed with RS256
 */
@Injectable()
export class AuthService {
  /**
   * Authenticates a user and returns access tokens
   * @param credentials - User login credentials
   * @returns Authentication result with tokens
   * @throws {InvalidCredentialsError} If credentials are invalid
   */
  async login(credentials: LoginCredentials): Promise<AuthResult> {
    // Implementation
  }
}

3. Create an ADR

# ADR-001: TypeScript Strict Mode Configuration

## Status
Accepted

## Context
What is the issue motivating this decision?

## Decision
What change are we proposing?

## Consequences
What becomes easier or more difficult?

4. Set Up CI/CD Pipeline

name: Documentation
on:
  push:
    branches: [main]
    paths: ['src/**', 'docs/**']

jobs:
  generate-docs:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: '20'
          cache: 'npm'
      - run: npm ci
      - run: npm run docs:generate
      - run: npm run docs:validate

5. Validate Documentation

{
  "rules": {
    "jsdoc/require-description": "error",
    "jsdoc/require-param-description": "error",
    "jsdoc/require-returns-description": "error",
    "jsdoc/require-example": "warn"
  }
}

If validation fails: review ESLint errors, fix JSDoc comments (add missing descriptions, add @param/@returns/@throws where absent), re-run eslint --ext .ts src/ until all errors pass before committing.

Examples

Documenting a React Hook

/**
 * Custom hook for fetching paginated data
 *
 * @remarks
 * This hook manages loading states, error handling, and automatic
 * refetching when the page or filter changes.
 *
 * @example
 * ```tsx
 * function UserList() {
 *   const { data, isLoading, error } = usePaginatedData('/api/users', {
 *     page: currentPage,
 *     limit: 10
 *   });
 *
 *   if (isLoading) return <Spinner />;
 *   if (error) return <ErrorMessage error={error} />;
 *   return <UserTable users={data.items} />;
 * }
 * ```
 *
 * @param endpoint - API endpoint to fetch from
 * @param options - Pagination and filter options
 * @returns Paginated response with items and metadata
 */
export function usePaginatedData<T>(
  endpoint: string,
  options: PaginationOptions
): UsePaginatedDataResult<T> {
  // Implementation
}

Documenting a Utility Function

/**
 * Validates email addresses using RFC 5322 specification
 *
 * @param email - Email address to validate
 * @returns True if email format is valid
 *
 * @example
 * ```typescript
 * isValidEmail('[email protected]'); // true
 * isValidEmail('invalid-email');      // false
 * ```
 *
 * @performance
 * O(n) where n is the email string length
 *
 * @see {@link https://tools.ietf.org/html/rfc5322} RFC 5322 Specification
 */
export function isValidEmail(email: string): boolean {
  const emailRegex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;
  return emailRegex.test(email);
}

NestJS Controller Documentation

/**
 * REST API endpoints for user management
 *
 * @remarks
 * All endpoints require authentication via Bearer token.
 * Rate limiting: 100 requests per minute per user.
 *
 * @example
 * ```bash
 * curl -H "Authorization: Bearer <token>" https://api.example.com/users/123
 * ```
 *
 * @security
 * - All endpoints use HTTPS
 * - JWT tokens expire after 1 hour
 * - Sensitive data is redacted from logs
 */
@Controller('users')
export class UsersController {
  /**
   * Retrieves a user by ID
   * @param id - User UUID
   * @returns User profile (password excluded)
   */
  @Get(':id')
  async getUser(@Param('id') id: string): Promise<UserProfile> {
    // Implementation

How to use typescript-docs on Cursor
AI-first code editor with Composer
1
Prerequisites
Before installing skills in Cursor, ensure your development environment meets these requirements:
›Cursor installed and configured on your development machine
›Node.js version 16.0+ with npm package manager (verify with node --version)
›Active project directory or workspace where you want to add typescript-docs
2
Execute installation command
Execute the skills CLI command in your project's root directory to begin installation:
$npx skills add https://github.com/giuseppe-trisciuoglio/developer-kit --skill typescript-docscopy
The skills CLI fetches typescript-docs from GitHub repository giuseppe-trisciuoglio/developer-kit and configures it for Cursor.
3
Select Cursor when prompted
The CLI will show a list of available agents. Use arrow keys to navigate and space to select Cursor:
◆ Which agents do you want to install to?
│
│ ── Universal (.agents/skills) ── always included ────
│   • Amp
│   • Antigravity
│   • Cline
│   • Codex
│ ●Cursor(selected)
│   • Cursor
│   • Windsurf
4
Verify installation
Confirm successful installation by checking the skill directory location:
.cursor/skills/typescript-docs
Reload or restart Cursor to activate typescript-docs. Access the skill through slash commands (e.g., /typescript-docs) or your agent's skill management interface.
⚠
Security & Verification Notice
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your development environment. Always verify the publisher's identity, review recent commits, and test in isolated environments before production deployment.
