# es6-error
[](https://www.npmjs.com/package/es6-error)
[](https://travis-ci.org/bjyoungblood/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
```javascript
import ExtendableError from 'es6-error';
class MyError extends ExtendableError {
// constructor is optional; you should omit it if you just want a custom error
// type for inheritance and type checking
constructor(message = 'Default message') {
super(message);
}
}
export default MyError;
```
## ES5 Usage
```javascript
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;
```
### Known Issues
- Uglification can obscure error class names ([#31](https://github.com/bjyoungblood/es6-error/issues/31#issuecomment-301128220))
#### Todo
- Better browser compatibility
- Browser tests
