@functional-examples/javascript

JavaScript/TypeScript extractor plugin for functional-examples.

Installation

npm install @functional-examples/javascript

Overview

This plugin adds JavaScript and TypeScript support to functional-examples:

• YAML frontmatter extraction from JS/TS files (comment-wrapped frontmatter)
• Automatic dependency tree resolution via dependency-tree
• TypeScript-aware file matching with configurable glob patterns

Usage

import { createJavaScriptPlugin } from '@functional-examples/javascript';
import type { Config } from 'functional-examples';

/**
 * Configuration for the JavaScript plugin example.
 *
 * This example demonstrates:
 * - Frontmatter metadata extraction (id, title, description, custom fields)
 * - Region markers for code snippets (#region / #endregion)
 *
 * Plugin options (all optional):
 * - skipFrontmatter: true  - Disable frontmatter parsing
 * - skipRegions: true      - Disable region extraction
 */
const config: Config = {
  plugins: [createJavaScriptPlugin()],
  scan: {
    include: ['**/*'],
    exclude: ['**/node_modules/**', '**/dist/**'],
  },
};

export default config;

Features

Frontmatter Extraction

The plugin detects YAML frontmatter in JS/TS comment blocks:

// ---
// title: My Example
// description: Demonstrates something useful
// tags: [typescript, async]
// ---

export async function main() {
  console.log('Hello!');
}

Dependency Resolution

When an entry point is specified, the plugin automatically resolves its dependency tree to discover related files.

Path Mappings

Configure path mappings to handle TypeScript path aliases in your examples.
