Getting the stored data

import express from "express";
import { verifySession } from "supertokens-node/recipe/session/framework/express";
import UserMetadata from "supertokens-node/recipe/usermetadata";

let app = express();

app.post("/updateinfo", verifySession(), async (req, res) => {
  const session = req.session;
  const userId = session.getUserId();

  const { metadata } = await UserMetadata.getUserMetadata(userId);

  res.json({ preferences: metadata.preferences });
});

Important

By default, all users have an empty metadata object.
