## ✅ Removed Legacy Files

The following old JavaScript files have been cleaned up:

### Removed Files:
- `src/mpesalib.js` - Old main JavaScript file
- `src/config/config.js` - Old configuration file
- `src/instance/instance.js` - Old factory class
- `src/routes/` - All old route classes (b2c, b2b, c2b, etc.)
- `src/utils/mpesautils.js` - Old utilities file
- `test/envtest.js` - Empty old test file
- `nbproject/` - NetBeans project files
- `.jshintrc` - JSHint configuration (replaced by ESLint)
- `.travis.yml` - Travis CI config (replaced by GitHub Actions)

### Why Removed:
1. **Complete Rewrite**: The library was completely rewritten in TypeScript
2. **Modern Architecture**: New service-oriented architecture replaces old patterns
3. **Better Structure**: Cleaner separation of concerns and modularity
4. **Type Safety**: Full TypeScript implementation with comprehensive types
5. **Modern Tooling**: ESLint, Jest, and GitHub Actions replace old tools

## 🎯 Benefits of Clean Structure

### 1. **Clarity**
- No confusion between old and new implementations
- Clear TypeScript-only codebase
- Modern project structure standards

### 2. **Maintainability**
- Single source of truth for all functionality
- Consistent coding patterns throughout
- Easy to navigate and understand

### 3. **Development Experience**
- Full TypeScript IntelliSense support
- No legacy code to maintain
- Modern development workflow

### 4. **Distribution**
- Clean NPM package without legacy files
- Smaller package size
- Professional appearance

## 📦 Package Contents

When published to NPM, the package will contain:
- `dist/` - Compiled JavaScript with type definitions
- `README.md` - Complete documentation
