Next.js and BlockNote ​

BlockNote is a component that should only be rendered client-side (and not on the server). If you're using Next.js, you need to make sure that Next.js does not try to render BlockNote as a server-side component.

Make sure to use BlockNote in a Client Component. You can do this by creating a separate file for your component (make sure this sits outside of your pages or app directory), and starting that with "use client"; directive:

"use client"; // this registers <Editor> as a Client Component
import { BlockNoteEditor } from "@blocknote/core";
import { BlockNoteView, useBlockNote } from "@blocknote/react";
import "@blocknote/core/style.css";

// Our <Editor> component we can reuse later
export default function Editor() {
  // Creates a new editor instance.
  const editor: BlockNoteEditor | null = useBlockNote({});

  // Renders the editor instance using a React component.
  return <BlockNoteView editor={editor} />;
}

Import as dynamic ​

Now, you can use Dynamic Imports to make sure BlockNote is only imported on the client-side.

You can import the component we just created above using next/dynamic in your page:

import dynamic from "next/dynamic";

const Editor = dynamic(() => import("./editor"), { ssr: false });

function App() {
  return (
    <div>
      <Editor />
    </div>
  );
}

This should resolve any issues you might run into when embedding BlockNote in your Next.js React app!
