The @types/jsdom package provides TypeScript type definitions for jsdom, a pure-JavaScript implementation of many web standards, notably the WHATWG DOM and HTML Standards. It allows for the simulation of a web browser's environment in Node.js, enabling the testing of web pages and applications without a browser. This package is essential for TypeScript developers working with jsdom, as it offers type checking and IntelliSense support in code editors.

What are @types/jsdom's main functionalities?

Creating a new JSDOM instance

This feature allows you to create a new JSDOM instance, simulating an HTML page. It is useful for testing and scraping web content in a Node.js environment.

import { JSDOM } from 'jsdom';
const dom = new JSDOM(`<html><body><p>Hello world</p></body></html>`);

Querying elements

After creating a JSDOM instance, you can query elements within the simulated page using standard DOM APIs, such as `querySelector`. This is particularly useful for testing DOM manipulation and event handling.

const paragraph = dom.window.document.querySelector('p');
console.log(paragraph.textContent); // Outputs: Hello world

Modifying elements

This feature demonstrates modifying the content of an element within the JSDOM instance. It's a common operation for testing dynamic web applications.

paragraph.textContent = 'Goodbye world';
console.log(dom.window.document.querySelector('p').textContent); // Outputs: Goodbye world
