    $ npm i @tradeshift/elements.file-uploader-input --save
    • Import the component
    import '@tradeshift/elements.file-uploader-input';


    <script src="node_modules/@tradeshift/elements.file-uploader-input/lib/file-uploader-input.umd.js"></script>
    • Use it like demo

    • Our components rely on having the Open Sans available, You can see the font-weight and font-style you need to load here, or you can just load it from our package (for now)

    <link rel="stylesheet" href="node_modules/@tradeshift/elements/src/fonts.css" />

    ➤ Polyfills

    For supporting IE11 you need to add couple of things

    • Don't shim CSS Custom Properties in IE11
    <!-- Place this in the <head>, before the Web Component polyfills are loaded -->
    	if (!window.Promise) {
    		window.ShadyCSS = { nativeCss: true };
    You have two options for polyfills library:
    1. Use @open-wc/polyfills-loader
    • Installation
    $ npm i @open-wc/polyfills-loader
    • Load it
    import loadPolyfills from '@open-wc/polyfills-loader';
    loadPolyfills().then(() => import('./my-app.js'));
    1. Use @webcomponents/webcomponentsjs
    • Installation
    $ npm i @webcomponents/webcomponentsjs --save
    • Enable ES5 class-less Custom Elements
    <script src="/node_modules/@webcomponents/webcomponentsjs/custom-elements-es5-adapter.js"></script>
    <script src="/node_modules/@webcomponents/webcomponentsjs/webcomponents-loader.js" defer></script>
