dom-serializer

What is dom-serializer?

The dom-serializer package is used to serialize DOM nodes to a string representation, typically HTML or XML. It is useful for transforming the DOM tree into a textual format that can be saved, transmitted, or manipulated as a string.

What are dom-serializer's main functionalities?

Serializing DOM nodes to HTML

This feature allows you to serialize a DOM node into an HTML string. The code sample demonstrates how to serialize a simple DOM element using dom-serializer.

const serialize = require('dom-serializer');
const dom = require('domhandler');
const root = new dom.Element('div', { class: 'container' });
const serialized = serialize(root);
console.log(serialized); // Outputs: <div class="container"></div>

Custom formatting options

dom-serializer allows for custom formatting options such as xmlMode, decodeEntities, and selfClosingTags. This code sample shows how to serialize a DOM element with XML formatting.

const serialize = require('dom-serializer');
const dom = require('domhandler');
const root = new dom.Element('div', { class: 'container' });
const options = { xmlMode: true };
const serialized = serialize(root, options);
console.log(serialized); // Outputs: <div class="container"/>

Other packages similar to dom-serializer

parse5

parse5 is a fast full-featured HTML parsing and serialization library. It provides a variety of modules for parsing, serializing, and manipulating HTML documents. Compared to dom-serializer, parse5 offers a more comprehensive suite of HTML processing capabilities.

jsdom

jsdom is a pure-JavaScript implementation of many web standards, notably the WHATWG DOM and HTML Standards. It creates a virtual DOM and is capable of serializing and manipulating it. While dom-serializer focuses on serialization, jsdom offers a broader range of features including DOM emulation, scripting, and event simulation.

htmlparser2

htmlparser2 is a forgiving HTML and XML parser. It can also be used in conjunction with domhandler to create a DOM tree which can then be serialized. It is similar to dom-serializer in that it can be used to serialize DOM structures, but it also includes robust parsing capabilities.
