Xerr

A better Error constructor can push errors into stack.

Getting Started

Install : npm i xerr

Examples

try {
	Object.bad();
} catch (err) {
	console.log( Error('call bad', err) );
	// JS native Error constructor show message only 'call bad'
}

Error = require('xerr');
console.log('\n=== After use xerr ===\n');

try {
	Object.bad();
} catch (err) {
	console.log( new Error('call bad', err) );
	// Show stacks 'call bad' & 'Object.bad is not a function' after used xerr
}

Other features

Error = require('xerr');

try {
	
	try {Object.bad();} catch (err) {
		throw new Error('call bad', err, {
			name: 'ServerError',
			data: 'Other info'
		});
	}

} catch (err) {
	var error = Error('a error', err);
	console.log('err.data: ', err.data);
	console.log('error: ', error);
	console.log('error.stacks: ', error.stacks);
}

API

var NativeError = Error

var Xerr = Error = require('xerr')

var err = Error(stringMessage, objectError, objectOpt) // Return a objectError

var err = Error(stringMessage, objectOpt)

var err = Error(stringMessage, objectError)

var err = Error(stringMessage)

var err = new Error(stringMessage)

err.stack // A better stack string that had all stack of objectErrors

err.stacks // A array filled by objectErrors

err[key] // Keys from objectOpt

Xerr.__ERROR__ // JS native Error constructor

NativeError.__XERR__ // Xerr constructor
