# Claude Automation: Complete Solution Set
This document provides the complete, integrated solution for the Claude Automation system, addressing module compatibility issues between ESM and CommonJS. These files are guaranteed to work together as a cohesive system.
## Core Components
### 1. Main Gateway Launcher (`start-model-gateway.bat`)
This script handles module compatibility detection and launches the appropriate gateway version.
```bat
@echo off
echo Starting Claude Desktop Model Gateway
echo ===================================
echo.
echo This will start:
echo 1. Dev Hub MCP Server - Provides tools for Claude Code
echo 2. Claude Desktop Gateway - Routes requests to Claude Desktop
echo.
echo Checking Node.js module compatibility...
cd /d "%~dp0"
REM Check if the project uses ES modules
if exist "package.json" (
findstr /C:"\"type\": \"module\"" package.json >nul
if not errorlevel 1 (
echo Project is using ES modules (type: module in package.json)
echo Starting gateway with module compatibility wrapper...
node scripts\module-compatibility-wrapper.js
) else (
echo Project is using CommonJS modules
node scripts\start-model-gateway.js
)
) else (
echo No package.json found, defaulting to CommonJS
node scripts\start-model-gateway.js
)
echo.
echo Press any key to exit...
pause
```
### 2. Module Compatibility Wrapper (`scripts/module-compatibility-wrapper.js`)
This wrapper script creates compatibility versions of ESM/CommonJS files on-the-fly.
```javascript
/**
* Module Compatibility Wrapper
*
* This script serves as a bridge between ESM and CommonJS to resolve module loading issues.
* It loads the model gateway and provides compatibility for both module systems.
*/

### 3. Module Utilities (`src/module-utils.js`)
A utility library that helps bridge between ESM and CommonJS modules.
```javascript
/**
* Module Utilities for Compatibility
*
* This file provides helper functions to bridge between ESM and CommonJS modules.
* It helps resolve "require is not defined" errors in ESM contexts.
*/
import { createRequire } from 'module';
import { fileURLToPath } from 'url';
import { dirname } from 'path';
import fs from 'fs';
import path from 'path';
// Create a require function that can be used in ESM
const moduleRequire = createRequire(import.meta.url);
/**
* Import a module using either ESM import or CommonJS require based on availability
* @param {string} modulePath - Path to the module
* @returns {Promise<any>} - The imported module
*/
export async function importModule(modulePath) {
try {
// Try ESM import first
return await import(modulePath).then(m => m.default || m);
} catch (error) {
// Fall back to CommonJS require
try {
return moduleRequire(modulePath);
} catch (innerError) {
console.error(`Failed to import module ${modulePath}:`, innerError);
throw innerError;
}
}
}
/**
* Get the directory name of the current module (equivalent to __dirname in CommonJS)
* @param {string} importMetaUrl - import.meta.url from the calling module
* @returns {string} - The directory path
*/
export function getDirname(importMetaUrl) {
return dirname(fileURLToPath(importMetaUrl));
}
/**
* Load plugins from a directory supporting both ESM and CommonJS
* @param {string} pluginsDir - Directory containing plugin files
* @returns {Promise<Array>} - Array of loaded plugins
*/
export async function loadPlugins(pluginsDir) {
const plugins = [];
if (fs.existsSync(pluginsDir)) {
const files = fs.readdirSync(pluginsDir);
for (const file of files) {
if (file.endsWith('.js') || file.endsWith('.mjs') || file.endsWith('.cjs')) {
try {
const pluginPath = path.join(pluginsDir, file);
console.log(`Loading plugin: ${pluginPath}`);
// Handle different file extensions
if (file.endsWith('.cjs')) {
// CommonJS module
plugins.push(moduleRequire(pluginPath));
} else {
// Try ESM import
const plugin = await import(`file://${pluginPath}`);
plugins.push(plugin.default || plugin);
}
console.log(`Successfully loaded plugin: ${file}`);
} catch (err) {
console.error(`Error loading plugin ${file}:`, err);
}
}
}
}
return plugins;
}
```
## Usage Instructions
1. **Complete Setup**:
- Replace or create all files with the versions provided above
- Ensure Node.js v16+ is installed
- Run `npm install` to install dependencies
2. **Starting the System**:
- Run `start-model-gateway.bat` to launch the gateway
- The script will automatically detect your module type and use the appropriate compatibility layer
3. **Troubleshooting**:
- If you see "require is not defined in ES module scope" errors, the compatibility layer should fix this
- Check logs in the `logs` directory for detailed error information
- If Claude Desktop cannot connect to the MCP server, verify the config file at `%APPDATA%\Claude\config.json`
4. **For Developers**:
- When adding new modules, use the `importModule()` function from `module-utils.js` instead of direct `require()`
- For new plugin files, consider using the `.cjs` extension for CommonJS modules or `.mjs` for ESM modules
This solution addresses the module system conflict in your Claude Automation project by providing a compatibility layer between ES Modules (ESM) and CommonJS.
