Linkedom is a lightweight, fast, and efficient library for working with DOM and HTML in Node.js environments. It provides a comprehensive set of APIs to manipulate and traverse the DOM, similar to what you would find in a browser environment.
DOM Manipulation
This feature allows you to parse HTML strings and manipulate the DOM elements. In this example, we parse an HTML string, select a div element by its ID, change its text content, and then output the modified HTML.
const { parseHTML } = require('linkedom');
const { document } = parseHTML('<html><body><div id="app"></div></body></html>');
const appDiv = document.getElementById('app');
appDiv.textContent = 'Hello, World!';
console.log(document.toString());Event Handling
Linkedom supports event handling similar to browser environments. This example demonstrates how to add an event listener to a button element and dispatch a click event programmatically.
const { parseHTML } = require('linkedom');
const { document, Event } = parseHTML('<html><body><button id="btn">Click me</button></body></html>');
const button = document.getElementById('btn');
button.addEventListener('click', () => console.log('Button clicked!'));
const event = new Event('click');
button.dispatchEvent(event);CSS Selector Queries
You can use CSS selectors to query elements in the DOM. This example shows how to select all list items with a specific class and log their text content.
const { parseHTML } = require('linkedom');
const { document } = parseHTML('<html><body><ul><li class="item">Item 1</li><li class="item">Item 2</li></ul></body></html>');
const items = document.querySelectorAll('.item');
items.forEach(item => console.log(item.textContent));jsdom is a popular library that simulates a browser environment in Node.js. It provides a full-featured DOM and HTML parser, making it suitable for testing and server-side rendering. Compared to linkedom, jsdom is more comprehensive but also heavier and slower.
Cheerio is a fast, flexible, and lean implementation of core jQuery designed specifically for the server. It parses HTML and XML documents and provides a jQuery-like API for DOM manipulation. Cheerio is lighter and faster than jsdom but does not support a full DOM environment like linkedom.
node-html-parser is a fast HTML parser that can parse and manipulate HTML documents. It is lightweight and efficient but does not provide a full DOM API like linkedom. It is suitable for simple HTML parsing and manipulation tasks.
