Development Guidelines

Code Style

• Use consistent indentation (2 spaces)
• Follow naming conventions:

  // Variables and functions in camelCase
  const myVariable = value;
  function doSomething() {}
  
  // Classes in PascalCase
  class MyClass {}
  
  // Constants in UPPER_SNAKE_CASE
  const MAX_SIZE = 1000;

• Add comments for complex logic
• Keep functions focused and small
• Use meaningful variable names

Testing

1. Unit Tests

   • Test individual functions
   • Mock dependencies
   • Cover edge cases

2. Integration Tests

   • Test component interactions
   • Test file processing
   • Test encryption/decryption

3. Browser Testing

   • Test in latest versions of:
     • Chrome
     • Firefox
     • Safari
     • Edge

Security Considerations

1. Data Handling

   • Never transmit sensitive data
   • Clear sensitive data from memory
   • Use secure random number generation

2. Encryption

   • Use standard encryption libraries
   • Implement proper key management
   • Follow security best practices

3. Input Validation

   • Validate all user inputs
   • Sanitize file inputs
   • Check file sizes and types

Performance

1. Image Processing

   • Optimize large image handling
   • Use WebWorkers for heavy tasks
   • Implement progress indicators

2. Memory Management

   • Clean up unused resources
   • Monitor memory usage
   • Handle large files efficiently

Documentation

• Update README.md for significant changes
• Document new features in API.md
• Include JSDoc comments for functions
• Update examples if needed
