Use Cases

Tusk's monkey patching capabilities can be applied in various scenarios. Here are some common use cases where Tusk shines:

Development and Debbuging

Feature Prototyping

Test new implementations without modifying the original codebase:

const math = {
    add: (a: number, b: number) => a + b
};
 
math.add = (a: number, b: number) => {
  return(a - b) * b;
};

Debugging

Add logging or debugging information to existing functions

const logger = {
    log: (message: string) => {
      console.log(`[${new Date().toISOString()}] ${message}`);
    },
    error: (message: string) => {
        console.log(`[${new Date().toISOString()} | ERROR] ${message}`)
    }
};
 
logger.error = (message: string) => {
    console.log(message + " | DEBUG")
}

Production scenarios

Hot fixes

Deploy critical fixed without full deployment cycles:

• Fix security vulnerabilities
• Patch performance issues
• Handle edge cases

A/B Testing

Implement different code paths for testing:

• Compare performance metrics
• Test user experience variations
• Validate bug fixes

Legacy Code Managment

API Compatibility

Maintain compatibility with older versions:

• Add missing methods
• Transform deprecated calls
• Bridge API differences

Feature Enhancement

Add modern capabilities to legacy systems:

• Implement async/await patterns
• Add type checking
• Enhance error handling

🧠 Pro Tip ╺╸ Monkey patching is perfect for quick fixes, but always aim for long-term solutions like PRs to upstream libraries!
