v2.0.0 - ESM + CommonJS Support

NodeSwarm v2.0.0 - Full ESM & CommonJS Support

🎉 Dual Module System

NodeSwarm now supports both ESM (ES Modules) and CommonJS with proper conditional exports!

✨ New Features

Module Support

• Full ESM support: Use import in modern projects (Vite, Next.js App Router, etc.)
• CommonJS support: Continue using require() in legacy projects
• Dual build system: Separate optimized builds for CJS (dist/cjs) and ESM (dist/esm)
• Proper conditional exports: Tree-shaking support in ESM builds
• Module type hints: package.json files in dist folders for better resolution
• Universal worker path resolution: Works seamlessly in both module systems

Technical Improvements

• Three separate build outputs: dist/cjs, dist/esm, dist/types
• Compatibility tests for both module systems
• Post-build fixes for cross-module compatibility
• Future-proof architecture for modern tooling

📦 Package Exports

{
  "main": "./dist/cjs/index.js",     // CommonJS entry
  "module": "./dist/esm/index.js",    // ESM entry  
  "types": "./dist/types/index.d.ts"  // TypeScript types
}

🚀 Usage

ESM (Modern)

import { ThreadPool } from 'nodeswarm';

const pool = new ThreadPool();
const result = await pool.thread((a, b) => a + b, 5, 10);
await pool.close();

CommonJS (Legacy)

const { ThreadPool } = require('nodeswarm');

(async () => {
  const pool = new ThreadPool();
  const result = await pool.thread((a, b) => a + b, 5, 10);
  await pool.close();
})();

✅ Compatibility

• ✅ Vite, Rollup, esbuild (ESM)
• ✅ Webpack 5 (both)
• ✅ Next.js App Router (ESM) & Pages Router (CJS)
• ✅ Node.js 12.20+ (for conditional exports)
• ✅ TypeScript (all module systems)
• ✅ Backward compatible - existing code works without changes

📝 Migration

No migration needed! Your existing CommonJS code continues to work:

// This still works exactly as before
const { ThreadPool } = require('nodeswarm');

New ESM projects can now use imports:

// New: Use ESM imports
import { ThreadPool } from 'nodeswarm';

🔧 Requirements

• Node.js 12.20+ for conditional exports support
• All features from v1.0.0 remain available
