Hi there,

What domain are you loading Express on? It will always show a watermark on localhost - the watermark is only removed in production.

Thanks,
Logan

Hello @Logan We are using it on Live (production domain)

Hi there,

Please make sure you are using @pdftron/pdfjs-express-viewer and not @pdftron/pdfjs-express

Thanks,

Hi @Logan

What if I am starting by adding the snippet directly into html code? There is no “import” involved here. This is my example:

<head>
    <title>PDF Viewer</title>
</head>
<body>
    <div id="viewer" style="width: 100%; height: 100%;"></div>

    <script src="../pdfjs/lib/webviewer.min.js"></script>
    <script>
        const queryString = window.location.search;
        const urlParams = new URLSearchParams(queryString);
        const pdfFile = urlParams.get('file');

        WebViewer({
            path: 'lib',
            licenseKey: 'License Key',
            initialDoc: pdfFile ? `../viewer/${pdfFile}` : 'about:blank',
        }, document.getElementById('viewer')).then(instance => {
            // PDF.js Express Viewer is now ready
                            instance.UI.setTheme('dark');

        });
    </script>
</body>
</html>

Thank you.
