zillow-browser-shims

Browser and JS language shims used by Zillow

Just require/import zillow-browser-shims, and the environment will be shimmed.

import 'zillow-browser-shims';

Included shims

• JS language shims from zillow-js-shims
• document.contains
• classlist-polyfill - Element.prototype.classList polyfill (only in browsers)
• raf - requestAnimationFrame polyfill for browsers and node
• requestIdleCallback
• whatwg-fetch - fetch polyfill (only in browsers, supports IE9+)
• TouchList[Symbol.iterator] - when Symbol and TouchList are both present
• element-closest - Element.prototype.closest polyfill (only in browsers)
• smoothscroll-polyfill - Scroll behavior specification polyfill (only in browsers)

Only browser shims

If you only want to bring in the browser shims and not the JS language shims (from zillow-js-shims), you can import zillow-browser-shims/browser-only. If you choose this route, you will want to be sure that you are properly bringing in the language shims for the browsers you support somehow. For example:

import 'zillow-js-shims/target/es2015';
import 'zillow-browser-shims/browser-only';
