Installation

Node & Browserify/Webpack

Installation of the npm package:

Browser

You can directly use the build provided at unpkg.com:

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

Usage

Basic named error

var CustomError = makeError("CustomError");

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

Advanced error class

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

var SpecializedError = makeError("SpecializedError", CustomError);

throw new SpecializedError(42);

Inheritance

Best for ES2015+.

import { BaseError } from "make-error";

class CustomError extends BaseError {
  constructor() {
    super("custom error message");
  }
}
