querystring

What is querystring?

The querystring npm package is used for parsing and formatting URL query strings. It provides utilities for working with the query string of a URL, such as parsing a query string into an object, stringifying an object into a query string, and handling escape and unescape of URL query strings.

What are querystring's main functionalities?

Parsing a query string

This feature is used to parse a URL query string into an object where each key-value pair is represented as a property.

const querystring = require('querystring');
const parsed = querystring.parse('foo=bar&abc=xyz&abc=123');

Stringifying an object

This feature converts an object into a URL query string, with proper formatting and escaping.

const querystring = require('querystring');
const stringified = querystring.stringify({ foo: 'bar', baz: ['qux', 'quux'], corge: '' });

Escaping and unescaping

These functions are used to manually escape and unescape query string values.

const querystring = require('querystring');
const escaped = querystring.escape('[e-mail]');
const unescaped = querystring.unescape('foo%40bar.com');
