Advanced tools
Package description
The domexception npm package provides a way to create DOMException objects, which represent exceptions that occur while interacting with the Document Object Model (DOM). This package is particularly useful when working with DOM-like structures in non-browser environments, such as Node.js, where the DOMException global is not available by default.
Creating a new DOMException
This feature allows you to create a new DOMException object with a custom error message and name. The name should be one of the DOMException error names, such as 'NotFoundError', 'SyntaxError', etc.
const DOMException = require('domexception');
const exception = new DOMException('Error message', 'NotFoundError');Checking the instance of DOMException
This feature is useful for checking if a given object is an instance of DOMException, which can be helpful for error handling and debugging.
const exception = new DOMException('Error message', 'NotFoundError');
console.log(exception instanceof DOMException); // trueThe 'error' package provides a way to create custom error objects in Node.js. It is similar to domexception in that it allows for the creation of error objects, but it does not specifically implement the DOMException interface.
The 'es6-error' package allows for the creation of custom errors that extend the built-in Error class. While it provides similar functionality in terms of creating error objects, it does not offer the specific DOMException types that domexception does.
Readme
This package implements the DOMException class, from web browsers. It exists in service of jsdom and related packages.
Example usage:
const DOMException = require("domexception");
const e1 = new DOMException("Something went wrong", "BadThingsError");
console.assert(e1.name === "BadThingsError");
console.assert(e1.code === 0);
const e2 = new DOMException("Another exciting error message", "NoModificationAllowedError");
console.assert(e2.name === "NoModificationAllowedError");
console.assert(e2.code === 7);
console.assert(DOMException.INUSE_ATTRIBUTE_ERR === 10);
This package exposes two flavors of the DOMException interface depending on the imported module.
domexception moduleThis module default-exports the DOMException interface constructor.
domexception/webidl2js-wrapper moduleThis module exports the DOMException interface wrapper API generated by webidl2js.
