removeScriptElement

Removes all scripts from the document.

SVGs can be interactive through JavaScript. However, unless the SVG is coming from a trusted source, it's strongly advised to strip off JavaScript to avoid XSS attacks.

caution

This will break interactive SVGs that rely on JavaScript.

This plugin performs the following operations:

Removes <script> elements.
Removes SVG event attributes, such as onload, onclick, and oninput, preserving the element itself.
Collapses <a> elements, moving children up to the parent element.

Usage

svgo.config.js
module.exports = {
  plugins: [
    "removeScriptElement"
  ]
}
