Full implementation here:

import express, { Request, Response } from "express";
import { ServerBlockNoteEditor } from "@blocknote/server-util";
import cors from "cors";

interface MarkdownRequest {
  markdown: string;
}

const app = express();
app.use(cors());
app.use(express.json());

app.post("/", async (req: Request<{}, {}, MarkdownRequest>, res: Response) => {
  const editor = ServerBlockNoteEditor.create();
  try {
    const blocks = await editor.tryParseMarkdownToBlocks(req.body.markdown);

    const YXmlFragment = editor.blocksToYXmlFragment(blocks);
    console.log(YXmlFragment);
    res.json(blocks);
  } catch (error) {
    console.error(error);
    res.status(500).json({ error: "Failed to process markdown" });
  }
});

app.listen(3000, "0.0.0.0", () => {
  console.log("Express server initialized on port 3000");
});

Before logging YXmlFragment, you need to add it to a Y.Doc.

Or use blocksToYDoc instead
