Introduction

The ErrorAnalysis interface is a key component of the error-enhanced library. It aims to provide in-depth error analysis, capturing the original error, stack frames, and more. The detailed data gathered through this interface can be highly beneficial for debugging and root cause analysis.

Properties

Property	Type	Description
originalError	Error | null	A read-only property representing the original error object, if available.
parsedStack	Array<StackFrame>	A read-only array containing the parsed stack frames from the original error.

Methods

Method	Return Type	Description
setOriginalError(originalError: Error)	this	Sets the original error object and triggers the extraction of the stack frames. Allows for method chaining.

Example Usage

const error = new ErrorEnhanced([
  new ErrorAnalysisEnhancer()
]);

// Setting properties
error.setOriginalError(new Error('Something went wrong'));

// Accessing properties
console.log(error.originalError);  // Original Error object
console.log(error.parsedStack);  // Parsed stack frames

Best Practices

• Use setOriginalError to set the original error object, which also populates parsedStack for better root cause analysis.

• Inspect properties like originalError and parsedStack for a comprehensive understanding of the error event.

Conclusion

The ErrorAnalysis interface offers a structured approach to capture in-depth error diagnostics. It is an essential component for effective error management and debugging.
