Sergei 1dd7eb8289 Remove hardcoded credentials and use environment variables
- Remove hardcoded database credentials from all scripts
- Remove hardcoded Legacy API tokens from backend scripts
- Remove hardcoded MQTT credentials from mqtt-test.js
- Update backend/.env.example with DB_HOST, DB_USER, DB_PASSWORD, DB_NAME
- Update backend/.env.example with LEGACY_API_TOKEN and MQTT credentials
- Add dotenv config to all scripts requiring credentials
- Create comprehensive documentation:
  - scripts/README.md - Root scripts usage
  - backend/scripts/README.md - Backend scripts documentation
  - MQTT_TESTING.md - MQTT testing guide
  - SECURITY_CREDENTIALS_CLEANUP.md - Security changes summary

All scripts now read credentials from backend/.env instead of hardcoded values.

# Security: Hardcoded Credentials Cleanup
## Summary
All hardcoded credentials have been removed from the codebase and replaced with environment variables.
## Changes Made
### 1. Updated Files (Removed Hardcoded Credentials)
#### Backend Scripts
- `backend/check-legacy-deployments.js` - Database and Legacy API credentials
- `backend/fix-legacy-deployments.js` - Legacy API token
- `backend/scripts/create-test-user.js` - Database credentials
- `backend/scripts/inspect-db.js` - Database credentials
#### Root Scripts
- `scripts/fetch-otp.js` - Database credentials
- `scripts/legacy-api/create_deployment.sh` - Legacy API token
- `mqtt-test.js` - MQTT credentials
### 2. Updated Configuration
#### backend/.env.example
Added the following environment variables:
```bash
# Database (PostgreSQL)
DB_HOST=your-db-host
DB_PORT=5432
DB_NAME=your-db-name
DB_USER=your-db-user
DB_PASSWORD=your-db-password
# Legacy API (eluxnetworks.net)
LEGACY_API_USERNAME=your-username
LEGACY_API_TOKEN=your-jwt-token
# MQTT Configuration
MQTT_BROKER=mqtt://mqtt.eluxnetworks.net:1883
MQTT_USER=your-mqtt-username
MQTT_PASSWORD=your-mqtt-password
```
### 3. New Documentation Files
- `scripts/README.md` - Documentation for root scripts
- `backend/scripts/README.md` - Documentation for backend scripts
- `MQTT_TESTING.md` - MQTT testing guide
- `SECURITY_CREDENTIALS_CLEANUP.md` - This file
## Required Action
### Before Running Scripts
Ensure that `backend/.env` contains all required credentials:
```bash
# Database
DB_HOST=eluxnetworks.net
DB_PORT=5432
DB_NAME=wellnuo_app
DB_USER=your-username
DB_PASSWORD=your-password
# Legacy API
LEGACY_API_USERNAME=robster
LEGACY_API_TOKEN=your-actual-jwt-token
# MQTT
MQTT_BROKER=mqtt://mqtt.eluxnetworks.net:1883
MQTT_USER=your-mqtt-username
MQTT_PASSWORD=your-mqtt-password
```
## Security Best Practices
1. ✅ Never commit `.env` files (already in `.gitignore`)
2. ✅ Use environment variables for all credentials
3. ✅ Keep `.env.example` updated but without real values
4. ✅ Document required environment variables in README files
5. ✅ Review code regularly for accidentally committed secrets
## Remaining Credentials in Repository
The following files contain credentials but are acceptable:
### Documentation (Examples Only)
- `docs/API_INTEGRATION_REQUEST.md` - Example JWT format
- `docs/MQTT_NOTIFICATIONS_ARCHITECTURE.md` - Example usage
- `MQTT-DESCRIPTION.md` - Historical documentation with example commands
### Configuration (Git-Ignored)
- `backend/.env` - **Git-ignored** - Contains actual credentials
### Test Data (Git-Ignored)
- `wellnuoSheme/*.json` - Schema files (should be git-ignored)
### External Collections
- `api/Wellnuo_API.postman_collection.json` - Postman collection (expired test tokens)
## Verification
To verify no credentials are hardcoded in active code:
```bash
# Check for database passwords
grep -r "W31153Rg31" --exclude-dir=node_modules --exclude-dir=.git \
--exclude-dir=temp_serve --exclude-dir=wellnuoSheme
# Check for MQTT passwords
grep -r "anandk_8" --exclude-dir=node_modules --exclude-dir=.git \
--exclude-dir=temp_serve --exclude-dir=wellnuoSheme
# Check for JWT tokens (should only be in .env and docs)
grep -r "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9" \
--exclude-dir=node_modules --exclude-dir=.git \
--exclude-dir=temp_serve --exclude-dir=wellnuoSheme \
--exclude-dir=api
```
## Status
**All hardcoded credentials removed from active code**
**Environment variables configured**
**Documentation updated**
**Scripts updated to use .env**
## Next Steps
1. Review `backend/.env` and ensure all credentials are up to date
2. Update any expired JWT tokens
3. Consider rotating credentials that were previously hardcoded
4. Add `wellnuoSheme/` to `.gitignore` if it contains sensitive data
