ohif:polyfill

This package provides polyfills for older browsers which make them compatible with the application.

Creating assets

Every polyfill shall be added as an asset JS file in the Meteor package definition file (package.js) and its file shall be placed inside the public/js directory. Adding these files as assets will prevent them from being loaded on all browsers without need. These files are exposed to the client and can be accessed through the application's /packages/ohif_polyfill/public/js/ URI.

Enabling polyfills

In order to enable a polyfill for a specific browser, a JS file shall be created inside the package's client directory with the browser name. We must check the current browser to include the polyfills, and to enable a polyfill we need something like this:

import { absoluteUrl } from './lib/absoluteUrl';

if (navigator && /BrowserID/.test(navigator.userAgent)) {
    const src = absoluteUrl('/packages/ohif_polyfill/public/js/mypolyfill.min.js');
    document.write(`<script src="${src}"><\/script>`);
}
