The query-string library is a Node.js library that provides a simple way to parse and stringify query strings. It is useful for working with the query string portion of a URL, which is the part of the URL that follows 'the "?" character and contains key-value pairs.

URI.js is a lightweight JavaScript library for working with URLs and URIs in Node.js and the browser. It provides a simple and consistent interface for parsing, manipulating, and building URLs and URIs.

Example Use

import queryString from 'query-string';

console.log(location.search);
//=> '?foo=bar'

const parsed = queryString.parse(location.search);
console.log(parsed);
//=> {foo: 'bar'}

console.log(location.hash);
//=> '#token=bada55cafe'

const parsedHash = queryString.parse(location.hash);
console.log(parsedHash);
//=> {token: 'bada55cafe'}

parsed.foo = 'unicorn';
parsed.ilike = 'pizza';

const stringified = queryString.stringify(parsed);
//=> 'foo=unicorn&ilike=pizza'

location.search = stringified;
// note that `location.search` automatically prepends a question mark
console.log(location.search);
//=> '?foo=unicorn&ilike=pizza'

const URI = require('uri-js');

// parse url for values
const parsedUrl = URI.parse("https://www.example.com/search?q=query+string#fragment");
console.log(parsedUrl);
/* Output:
{
    scheme: 'https',
    authority: 'www.example.com',
    path: '/search',
    query: 'q=query+string',
    fragment: 'fragment'
}
*/

// create url from values
const urlComponents = {
    scheme: 'https',
    authority: 'www.example.com',
    path: '/search',
    query: 'q=query+string',
    fragment: 'fragment'
};
const url = URI.serialize(urlComponents);
console.log(url);
// Output: 'https://www.example.com/search?q=query+string#fragment'
