SVG classList Polyfill

Polyfill for classList methods (contains, add, remove, toggle) on SVG elements which aren't supported on IE11 and other older browsers.

Installation and Usage

npm install svg-classlist-polyfill
import 'svg-classlist-polyfill'

That's it, polyfill will only be added if current environment doesn't already support the methods. Here is how regular usage afterwards might look like:

const icon = document.querySelector('svg.icon')

icon.classList.add('icon--blue')
icon.classList.toggle('icon--rotate')
icon.classList.remove('icon--blue')
icon.classList.contains('icon--blue') === false

Avoid setting the class with icon.className = 'icon icon--blue' as this isn't properly supported in IE11 and will not work together with the polyfill.

Tests

There are a few test cases available in test.js. Serve a simple website with npm test opening this in a browser will run a few test cases quickly indicating whether the polyfill is working well.
