Access GET parameters in Express on Node.js
David Y.
—The Problem
How do I access GET parameters in a URL’s query string in a Node.js Express application?
The Solution
We can access the GET parameters of the current URL using req.query():
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:
GET parameters: {"id":"1","firstname":"Jane","surname":"Doe"}
