Common Mistakes

Using 'http' instead of 'express' will not provide the router function.

Using 'path' or 'router' as module names will cause errors.

Common Mistakes

Exporting 'express' or 'app' will not export your router routes.

Using 'require' here is incorrect syntax.

You export the router object so other files can use it.

Common Mistakes

Using 'get' instead of 'use' will not mount the router correctly.

Passing 'listen' or 'app' instead of the router will cause errors.

Use app.use to mount the router middleware at the '/api' path.

Fill all three blanks to create a router with a POST route and export it.

Express

const express = require('express');
const router = express.Router();
router.[1]('/submit', (req, res) => {
  res.[2]('Data received');
});
module.exports = [3];

💡 Hint

Common Mistakes

Using 'get' instead of 'post' changes the route behavior.

Forgetting to export the router will make it unusable elsewhere.

This code defines a POST route on the router and exports it for use in other files.
