es6-error
An easily-extendable error class for use with ES6 classes (or ES5, if you so
choose).
Tested in Node 4.0, Chrome, and Firefox.
Why?
I made this because I wanted to be able to extend Error for inheritance and type
checking, but can never remember to add
Error.captureStackTrace(this, this.constructor.name)
to the constructor or how
to get the proper name to print from console.log
.
ES6 Usage
import ExtendableError from 'es6-error';
class MyError extends ExtendableError {
constructor(message = 'Default message') {
super(message);
}
}
export default MyError;
ES5 Usage
var util = require('util');
var ExtendableError = require('es6-error');
function MyError(message) {
message = message || 'Default message';
ExtendableError.call(this, message);
}
util.inherits(MyError, ExtendableError);
module.exports = MyError;
