fluent-url

A chainable version of the global URL class

Installation

npm install fluent-url

Goals

A simple class that uses URL and URLSearchParams built-ins in a fluent (chainable) manner.

Example Usage

import url from 'fluent-url';

// simple construction with query string
const endpoint = url('https://api.example.com/search', { term: 'Foo' });
endpoint.href();
// => "https://api.example.com/search?term=Foo"

// chainable example
const endpoint = url('https://api.example.com/search?term=Foo');
endpoint
	.port('8080')
	.search({
		b: 'two',
		a: 'one',
	})
	.sort()
	.path('/login')
	.hash('#username')
	.href();
// => "https://api.example.com:8080/login?a=one&b=two#username"

// extend search query instead of overwriting it
const endpoint = url('https://api.example.com/search?term=Foo');
endpoint.qsExtend({
	limit: 10,
	sort: 'created_at',
});
endpoint.href();
// => "https://api.example.com/search?term=Foo&limit=10&sort=created_at"

// manipulate relative URLs
url('/search?term=Foo').qsAppend('limit', 10).href();
// => "/search?term=Foo&limit=10"

Instantiating

FluentURL can be instantiated using multiple signatures:

url(myUrl); // myUrl may be string or instance of URL
url(myUrl, searchParams); // searchParams is a plain object or instance of URLSearchParams
url(relative, base); // relative is the path and base is a string with protocol, port, domain
url(relative, base, searchParams); // searchParams is a string, plain object or instance of URLSearchParams

URL Built-in Methods

URL built-in	FluentURL get	FluentURL set	Description	Example
.hash	.hash()	.hash(newHash)	The hash string including "#"	#foo
.host	.host()	.host(newHost)	The domain name including port if applicable	sub.example.com:8443
.hostname	.hostname()	.hostname(newHost)	The domain name excluding port	sub.example.com
.href	.href()	.href(newHref)	The entire URL - same as .toString()	http://example.com/foo?bar#baz
.origin	.origin()	N/A	The protocol, domain and port	http://example.com:8443
.password	.password()	.password(newPassword)	The password	ftp-password
.pathname	.pathname()	.pathname(newPathname)	The path including leading slash	/admin
.port	.port()	.port(newPort)	The port number as a string	8080
.protocol	.protocol()	.protocol(newProtocol)	The scheme	https:
.search	.search()	.search(newSearch)	The search string, plain object, or URLSearchParams object	?a=one&b=two
.toString()	.toString()	N/A	The entire URL	http://example.com/foo?bar#baz
.username	.username()	.username(newUsername)	The username string	ftpuser

Custom Methods

Method	Description
.clone()	Create a new URL with the same values
.export(props)	Export all or the given subset of url attributes
.import(values)	Import the given pieces
.isRelative()	True if the URL is relative (e.g. starts with a dot or slash)
.makeRelative()	Control whether URL is relative
.searchObject([obj])	Get or set query string params as object

Query String Methods

URLSearchParams built-in	FluentURLSearchParams	Description
append()	.qsAppend(name, value)	Add a single param
N/A	.qsClear()	Delete all params - same as .qsDeleteAll() and .qsReset()
.delete(name)	.qsDelete(name)	Delete one param
N/A	.qsDeleteAll()	Delete all params - same as .qsClear() and .qsReset()
.entries()	.qsEntries()	Get an iterable param set
N/A	.qsExtend(withParams)	Set params by string, URLSearchParams object, or plain object
.forEach(callback, thisArg)	.qsForEach(callback, thisArg)	Iterate through params
.get(name)	.qsGet(name)	Get the value of a single param by name
.getAll(name)	.qsGetAll(name)	Get the value of a all params with name
.has(name)	.qsHas(name)	Check if the given param is present
.keys()	.qsKeys()	Get an array of all param names
N/A	.qsReset()	Clear out all params - same as .qsClear() and .qsDeleteAll()
.set(name, value)	.qsSet(name, value)	Set one param
N/A	.qsSetAll(params)	Reset then set params by string, URLSearchParams object, or plain object
.sort()	.qsSort()	Sort params alphabetically (helpful for comparison or caching)
.values()	.qsValues()	Get an array of all param values

Wait, what is FluentURLSearchParams? It is a class used internally for all the qs* methods. Its methods are named without the qs such as append(), clear(), delete(), etc. If you would like to use it directly, it is exported by name so it can be used like this:

import url, { FluentURLSearchParams } from 'fluent-url';
const FluentURLSearchParams = require('fluent-url').FluentUrlSearchParams;

Properties

Name	Description
.URL	The URL object
.fluentParams	The FluentURLSearchParams object
.fluentParams.searchParams	Reference to .URL.searchParams

Hash routing URLs

fluent-url supports manipulating URLs that have hash routing:

import url from 'fluent-url';

// simple construction with query string
const controller = url('https://example.com/home#/dashboard?msg=Hello');
controller.hashPath(); // "/dashboard"
controller.hashSearch(); // { msg: "Hello" }

controller
	.hashPath('/projects')
	.hashSearch({ query: 'new construction', sort: '-created' })
	.href(); // https://example.com/home#/projects?query=new+construction&sort=-created
