NodeJS - WITHOUT EXPRESS - how to get query-params?

Question

I call my app by localhost:3000?paramname=12345

inside NodeJS I have

server.js

var http = require('http');
var app = require('./app');

var server = http.createServer(app.handleRequest).listen(3000, function ()  {
    console.log('Server running on Port 3000');
});

and my app.js

var url = require('url');
var path = require('path');

function handleRequest(req, res) {
    // parse url and extract URL path
    var pathname = url.parse(req.url).pathname;  

    // file extention from url
    const ext = path.extname(pathname); 

    console.log(req.url); 

});

now the console.log(req.url) would output me /?paramname=12345

but how would i get only the var-name paramname or it's value 12345 ??

when I try everything i find, but I onl get undefined or the script brakes because no such function.

Answer 1

You can use the built-in querystring module:

const querystring = require('querystring');

...
const parsed = url.parse(req.url);
const query  = querystring.parse(parsed.query);

Answer 2

you can use 'url' moduele for getting query params in pure Nodejs (without express) below are some code snippets-
