Ways to troubleshoot and fix the issue of encountering an unexpected

Here is the code snippet I am dealing with:

import * as errorHandler from "errorhandler";

import { default as app } from "./express";
import * as cors from "cors";
/**
 * Error Handler. Provides full stack - remove for production
 */
app.use(errorHandler());

I encountered the following error:

(function (exports, require, module, __filename, __dirname) { import * as errorHandler from "errorhandler"; SyntaxError: Unexpected token import

Any suggestions or assistance on resolving this issue would be greatly appreciated.

Answer №1

In its default mode, Node.js does not offer built-in support for ECMAScript-style modules (like the import syntax). You can either run your application with the flag --experimental-modules or switch to using require() instead. For more details, you can refer to the official documentation.
