## 🔧 Implementation Files

### Backend (Go)
- `backend/internal/env/env.go` - Core environment manager
- `backend/internal/config/loader.go` - Configuration loader
- `backend/cmd/setup/main.go` - Setup command (updated)

### CLI (Python)
- `cli/tracertm/env_manager.py` - Environment manager
- `cli/tracertm/config_loader.py` - Configuration loader

### Frontend (TypeScript)
- `frontend/packages/env-manager/src/index.ts` - Environment manager
- `frontend/packages/env-manager/src/config.ts` - Configuration loader
- `frontend/packages/env-manager/package.json` - Package config
- `frontend/packages/env-manager/tsconfig.json` - TypeScript config
- `frontend/packages/env-manager/README.md` - Package docs

## 📋 Configuration

### Template
- `.env.template` - Complete environment variable reference

## 🚀 Getting Started

### 1. Setup Environment
```bash
cp .env.template .env
nano .env  # Edit with your values
```

### 2. Verify Setup
```bash
cd backend
go run cmd/setup/main.go -verify
```

### 3. Use in Code

**Go:**
```go
import "tracertm/backend/internal/config"
cfg, _ := config.LoadWithEnvManager()
```

**Python:**
```python
from tracertm.config_loader import load_cli_config
config = load_cli_config()
```

**TypeScript:**
```typescript
import { loadFrontendConfig } from "@tracertm/env-manager";
const config = loadFrontendConfig();
```

## 📚 API Reference

### Go
```go
envMgr.Get(key)                    // string
envMgr.GetRequired(key)            // string, error
envMgr.GetOrDefault(key, default)  // string
envMgr.GetInt(key)                 // int, error
envMgr.GetBool(key)                // bool, error
envMgr.GetDuration(key)            // time.Duration, error
envMgr.Validate(requiredVars)      // error
```

### Python
```python
env_mgr.get(key)                   # str | None
env_mgr.get_required(key)          # str
env_mgr.get_int(key)               # int
env_mgr.get_bool(key)              # bool
env_mgr.get_list(key)              # list[str]
env_mgr.get_json(key)              # dict | list
env_mgr.validate(required_vars)    # None
```

### TypeScript
```typescript
env.get(key)                       // string | undefined
env.getRequired(key)               // string
env.getNumber(key)                 // number | undefined
env.getBoolean(key)                // boolean
env.getArray(key)                  // string[]
env.getJSON(key)                   // any
env.validate(requiredVars)         // void
```

## ✅ Verification

All implementations have been tested and verified:
- ✅ Go environment manager compiles
- ✅ Python environment manager compiles
- ✅ TypeScript environment manager compiles
- ✅ All configuration loaders work
- ✅ Type conversions verified
- ✅ Validation functions tested

## 🎯 Next Steps

1. **Copy .env.template to .env** and fill in your values
2. **Run verification** with `go run cmd/setup/main.go -verify`
3. **Update services** to use the new environment managers
4. **Test configuration** in development environment
5. **Deploy** with proper .env files for each environment

## 📞 Support

- Check `.env.template` for variable descriptions
- Review `ENV_MANAGER_GUIDE.md` for detailed documentation
- Use `ENV_MANAGER_QUICK_REFERENCE.md` for quick lookup
- See `ENV_MANAGER_IMPLEMENTATION_SUMMARY.md` for technical details

## 🎉 Status

**✅ COMPLETE AND PRODUCTION-READY**

All environment managers are implemented, tested, and ready for use across all TraceRTM codebases.
