Advanced tools
@wordpress/escape-html is a utility package for escaping HTML entities in strings. It helps prevent XSS (Cross-Site Scripting) attacks by converting special characters into their corresponding HTML entities.
Escape HTML
This feature allows you to escape HTML entities in a string, converting special characters like <, >, and & into their corresponding HTML entities.
const { escapeHTML } = require('@wordpress/escape-html');
const unsafeString = '<script>alert("XSS")</script>';
const safeString = escapeHTML(unsafeString);
console.log(safeString); // <script>alert("XSS")</script>Escape Attribute
This feature allows you to escape HTML attributes, ensuring that special characters are converted to their corresponding HTML entities.
const { escapeAttribute } = require('@wordpress/escape-html');
const unsafeAttribute = '" onmouseover="alert(1)"';
const safeAttribute = escapeAttribute(unsafeAttribute);
console.log(safeAttribute); // " onmouseover="alert(1)"The 'he' package is a robust HTML entity encoder/decoder. It supports both encoding and decoding of HTML entities and is highly configurable. Compared to @wordpress/escape-html, 'he' offers more flexibility and options for handling HTML entities.
The 'html-escaper' package provides simple functions to escape and unescape HTML entities. It is lightweight and easy to use, similar to @wordpress/escape-html, but with a focus on simplicity and minimalism.
The 'lodash.escape' function is part of the Lodash library, which provides utility functions for common programming tasks. It escapes characters for inclusion in HTML, similar to @wordpress/escape-html, but is part of a larger utility library.

Install the module

This package assumes that your code will run in an ES2015+ environment. If you're using an environment that has limited or no support for ES2015+ such as lower versions of IE then using core-js or @babel/polyfill will add support for these methods. Learn more about it in Babel docs.

Returns a string with ampersands escaped. Note that this is an imperfect implementation, where only ampersands which do not appear as a pattern of named, decimal, or hexadecimal character references are escaped. Invalid named references (i.e. ambiguous ampersand) are are still permitted.
