Code Architecture
JavaScript/TypeScript Structure
The application follows object-oriented principles with a main Bank class that handles:
- Account management
- Balance calculations
- Transaction processing
- User data storage
- Business logic validation
Key Classes and Methods
Bank Class
- Constructor: Initialize bank instance
- createAccount(): Create new user account
- getBalance(): Retrieve account balance
- transfer(): Execute money transfer
- getTransactionHistory(): Retrieve transaction records
- authenticate(): Verify user credentials
Responsive Design
The application is fully responsive and optimized for:
- Desktop: 1920px and above
- Tablet: 768px - 1024px
- Mobile: Below 768px
CSS media queries ensure optimal viewing experience across all devices.
Browser Compatibility
| Browser | Support |
|---|---|
| Chrome | ✓ Full Support |
| Firefox | ✓ Full Support |
| Safari | ✓ Full Support |
| Edge | ✓ Full Support |
| IE 11 | ✗ Not Supported |
Security Considerations
While this is a demonstration/educational application, production use should implement:
- Backend Validation: All inputs must be validated on the server
- Encryption: Sensitive data should be encrypted in transit (HTTPS)
- Authentication: Implement secure session management
- Data Protection: Use secure storage for sensitive information
- Input Sanitization: Prevent XSS attacks through proper input handling
Development
TypeScript Setup
If you want to work with TypeScript:
- Install TypeScript globally:
npm install -g typescript
- Compile TypeScript:
tsc Bank.ts --outFile Bank.js
Code Style
- Follow consistent naming conventions
- Use meaningful variable and function names
- Add comments for complex logic
- Maintain clean, readable code structure
Performance Optimization
Current optimizations include:
- Minimal CSS and JavaScript files
- Efficient DOM manipulation
- Local storage for user data persistence
- Optimized asset loading
Future Improvements
- Implement caching strategies
- Minify CSS and JavaScript for production
- Lazy load components where applicable
- Use service workers for offline functionality
Deployment
The application is currently deployed on Vercel:
Live URL: aplikasi-bank.vercel.app
Deploying Your Own Version
- Push code to GitHub
- Connect repository to Vercel
- Configure build settings
- Deploy automatically on push
# Manual deployment using Vercel CLI
