[!WARNING]

Use dynamic import if you are using ESM. Example:

import {  register } from "infrastack-interview-fs-bs";
register({
  endpoint: OTEL_COLLECTOR_URL,
  instruments: ["http", "express"],
  logLevel: DiagLogLevel.DEBUG,
  serviceName: "auth-service",
});
(async () => {
  const express = await import("express");

  const app: Express = express.default();
  const port = parseInt(process.env.PORT || "3000", 10);
  
  app.listen(port, () => {
    console.log(`[server]: Server is running at http://localhost:${port}`);
  });
})();
