Node.js Query String Methods

• querystring.parse(str) ÔÇö converts a query string into a JSON object.
• querystring.stringify(obj) ÔÇö converts a JSON object into a query string.

Example 1: Using parse()

const querystring = require('querystring');
const obj1 = querystring.parse('name=sonoo&company=updategadh');
console.log(obj1);

// Output: { name: 'sonoo', company: 'updategadh' }

Example 2: Using stringify()

const querystring = require('querystring');
const qs1 = querystring.stringify({ name: 'sonoo', company: 'updategadh' });
console.log(qs1);

// Output: name=sonoo&company=updategadh

Modern Alternative: URLSearchParams

In modern Node.js, the built-in URLSearchParams class is often preferred over the legacy querystring module:

const params = new URLSearchParams('name=sonoo&company=updategadh');
console.log(params.get('name')); // sonoo
console.log(params.toString());   // name=sonoo&company=updategadh
