# Task Completion Checklist

## When a Development Task is Completed

### Code Quality Checks
⚠️ **Note**: This project currently has NO configured linting, formatting, or testing tools.

**Recommended Actions**:
1. **Manual Code Review**: Carefully review code changes for:
   - Syntax errors
   - Logic errors
   - Consistent code style
   - Proper error handling
   - Security considerations (no hardcoded secrets)

2. **Manual Testing**: 
   - Start the development server: `yarn dev`
   - Test the affected functionality manually
   - Check API endpoints with tools like Postman or curl
   - Verify Web App functionality in browser
   - Test Telegram bot integration if applicable

### Environment Verification
1. **Dependencies**: Ensure all required packages are installed (`yarn install`)
2. **Environment Variables**: Verify `.env` file is properly configured
3. **External Dependencies**: Ensure FFmpeg is installed and accessible
4. **Database**: Check that SQLite database initializes correctly

### Testing Checklist
Since no automated testing exists, manually verify:
- [ ] Server starts without errors
- [ ] API endpoints respond correctly
- [ ] YouTube search functionality works
- [ ] MP3 conversion process completes
- [ ] File downloads work properly
- [ ] Database operations succeed
- [ ] Telegram Web App loads correctly

### Deployment Preparation
- [ ] Environment variables are set correctly
- [ ] All dependencies are in package.json
- [ ] No hardcoded secrets in code
- [ ] Downloads directory is created properly
- [ ] FFmpeg is available in production environment

### Git Workflow
- [ ] Review all changes before committing
- [ ] Use meaningful commit messages
- [ ] Ensure no sensitive data is committed
- [ ] Check .gitignore includes necessary exclusions

### Future Improvements
Consider adding in future iterations:
- ESLint for code linting
- Prettier for code formatting
- Jest or Mocha for testing
- TypeScript for type safety
