vanilla-js-url

A lightweight module to construct and parse query parameters of URLs.

A set of functions for working with url. Easy to add parameters to url, easy to extract parameters from url. You can also get path from url.

simple get, simple add

Demo

Install

npm i vanilla-js-url

or

yarn add vanilla-js-url

Get started

wurl.getParams('example.com?bar=1&foo');
wurl.addParams('example.com', { bar: 1, foo: 2 });

wurl.getPath('example.com/path/to/page');

wurl.getParamsExtended('example.com?bar[roo][boo]=1&foo[puu]=test');
wurl.addParamsExtended('example.com', { bar: { foo: 'test', joo: 2 } });

getParams(url, decode)

alias get()

param	type	default
url	String	window.location.href
decode	Boolean	true

If you have simple parameters like bar=1 or foo[]=3&foo[]=5, then use getParams().
In response, you will get a simple (single-level) object whose keys will contain either simple values or simple arrays. This function is suitable in 99% of cases.

wurl.get('example.com');
// {}

wurl.get('example.com?bar=1&foo');
// { bar: '1', foo: '' }

wurl.get('example.com?bar=1&bar=2');
// { bar: '2' }

wurl.get('example.com?bar[]=1&bar[]=2');
// { bar: ['1', '2'] }

wurl.get('example.com?bar=1&bar[]=2');
// { bar: ['2'] }

addParams(url, params, encode)

alias add()

param	type	default
url	String	required
params	Object	required
encode	Boolean	false

wurl.add('example.com', { bar: 1, foo: 2 });
// example.com?bar=1&foo=2

wurl.add('example.com?bar=1&foo', { bar: 2, foo: 2 });
// example.com?bar=2&foo=2

wurl.add('example.com?bar=1', { bar: [2, 3] });
// example.com?bar[]=2&bar[]=3

wurl.add('example.com?bar=1&bar[]=2', { bar: [3, 4] });
// example.com?bar[]=2&bar[]=3&bar[]=4

getPath(url)

alias path()

param	type	default
url	String	window.location.href

wurl.path('https://example.com/path/to/page?bar=1');
// /path/to/page

getParamsExtended(url)

alias getExt()

param	type	default
url	String	window.location.href

If you have complex parameters like: bar[foo][too][poo]=3&bar[foo][goo]=4, then use getParamsExtended().
In response, you will get a multi-level object. Most likely you will not need this function.

wurl.getExt('example.com?bar[t]=1&bar[j]=2');
// { bar: { t: '1', j: '2' } }

addParamsExtended(url, params)

alias addExt()

param	type	default
url	String	required
params	Object	required

wurl.addExt('example.com', { bar: { foo: 'test', joo: 2 } });
// example.com?bar[foo]=test&bar[joo]=2

The getParamsExtended and addParamsExtended functions may not answer exactly. Please tell me which tests failed.
