  </div>
</PdfFocusProvider>

Next.js

NextJs applications may need to update their configuration to be compatible with react-pdf v9 and pdfjs v4 If you have issues related to canvas, you can add the following to your next.config.js:

module.exports = {
+ webpack: (config) => {
+   config.resolve.alias.canvas = false;

+   return config;
+ },
}

Another common issue is: TypeError: Promise.withResolvers is not a function To fix this issue, you need to use dynamic imports for the PDF component (to indicate to NextJs to use it for client-side rendering only).

- import { PDFViewer, PdfFocusProvider } from "@llamaindex/pdf-viewer";

+ import dynamic from "next/dynamic";

+ // Dynamic imports for client-side rendering only
+ const PDFViewer = dynamic(
+   () => import("@llamaindex/pdf-viewer").then((module) => module.PDFViewer),
+   { ssr: false },
+ );

+ const PdfFocusProvider = dynamic(
+   () =>
+     import("@llamaindex/pdf-viewer").then((module) => module.PdfFocusProvider),
+   { ssr: false },
+ );
