The Solution

We can access the GET parameters of the current URL using req.query():

Click to Copy
const express = require("express"); const app = express(); app.get("/", (req, res) => { res.send(`GET parameters: ${JSON.stringify(req.query)}`); }); app.listen(8000);

Given the URL http://localhost:8000?id=1&firstname=Jane&surname=Doe, this code will return an HTTP response with the following content:

Click to Copy
GET parameters: {"id":"1","firstname":"Jane","surname":"Doe"}
