> Make your own error types!


## Features

- Compatible Node & browsers
- `instanceof` support
- `error.name` & `error.stack` support
- compatible with [CSP](https://en.wikipedia.org/wiki/Content_Security_Policy) (i.e. no `eval()`)

## Installation

### Node & [Browserify](http://browserify.org/)/[Webpack](https://webpack.js.org/)

Installation of the [npm package](https://npmjs.org/package/make-error):

```
> npm install --save make-error
```

Then require the package:

```javascript
var makeError = require('make-error');
```

### Browser

You can directly use the build provided at [unpkg.com](https://unpkg.com):

```html
<script src="https://unpkg.com/make-error@1/dist/make-error.js"></script>
```

## Usage

### Basic named error

```javascript
var CustomError = makeError('CustomError')

// Parameters are forwarded to the super class (here Error).
throw new CustomError('a message')
```

### Advanced error class

```javascript
function CustomError (customValue) {
  CustomError.super.call(this, 'custom error message')

  this.customValue = customValue
}
makeError(CustomError)

// Feel free to extend the prototype.
CustomError.prototype.myMethod = function CustomError$myMethod () {
  console.log('CustomError.myMethod (%s, %s)', this.code, this.message)
}

//-----

try {
  throw new CustomError(42)
} catch (error) {
  error.myMethod()
}
```

### Specialized error

```javascript
var SpecializedError = makeError('SpecializedError', CustomError);

throw new SpecializedError(42);
```

### Inheritance

> Best for ES2015+.

```javascript
import {BaseError} from 'make-error'

class CustomError extends BaseError {
  constructor () {
    super('custom error message')
  }
}
```
