npm version Build Status

manage the state of URL query string in an elegant way

This package was writen becuase I did`t find a package, that was parsed a query-string like I want it to be parsed (complex objects and array), and in the same time to manage the current state of the query-string, and have the option to listen to any changes that happend in query-string from another places in my code.

hope you will enjoy it 😎

Installation

$  npm install query-string-manager --save

Usage

// ES6 style
// current query-string = form[a]=a&form[b]=b&c=c
 
import queryStringManager from 'query-string-manager'
 
queryStringManager.listen((qs) => {
    console.log('listener called!')
})
 
// The method will read the current query string
queryStringManager.read()
//=> 'listener called!''
 
queryStringManager.get()
//=> {form: {a: 'a', b: 'b'}, c: 'c' }
 
queryStringManager.push('d', 'd')
//=> 'listener called!'
// and the current query string will be updated without refresh
 
queryStringManager.get()
//=> {form: {a: 'a', b: 'b'}, c: 'c', d: 'd'}

API

.read([string|null], [callListeners = true])

if the first argument is null the method will take location.search as first argument. the second argument is a boolean that by default call all the listeners that provide. The method returns this

queryStrinManager.read('?foo=bar&fi[a]=bar')
// will read the provided string and call all the listeners
 
queryStringManager.read(null, false)
// will read from location.search with out call all of the listeners

.get([key = null], [defaultVal = null])

when not providing and arguments its just return all the query-string parsed object

// ?foo=bar&form[a]=fifi
 
queryStringManager.get()
//=> { foo: 'bar', form: {a: 'fifi'} }

when providing an arguments its act just like the lodash get method

// ?foo=bar&form[a]=fifi
 
queryStringManager.get('form.a')
//=> 'fifi'
 
queryStringManager.get('form.b', 'default')
//=> 'default'

.set( string|object, [val = null] )

when the first argument is an regular string its act just like the lodash set method

queryStringManager.set('form.a', 'someValue').get()
//=> { form: {a: 'someValue'} }

when prviding an object the object will be merge to the main query-strign object.

// current queryStringManager Object { a: 'foo', foo: 'bar' }
 
queryStringManager.set({
    a: 'a'
    b: {
        foo: 'bar'
    }
}).get()
//=> {a: 'a', b: { foo: 'bar' }, foo: 'bar'}

.pushToUrl()

just like it`s sound replace the current query-string with the queryStringManager state. and call all the listeners

// url query-string = ?a=b
 
queryString.read()
queryStringManager.set({foo: 'bar'}).pushToUrl()
 
// url query-string = ?a=b&foo=bar

.push( string|object, [val = null] )

act just like .set() but also call pushToUrl() after the value was seted

.listen( callback )

add an callback function to the listeners array. when pushToUrl(), push() or read() are called. all the listeners that provied will be call.

queryStringManager.listen(() => {
    console.log('first call')
})
 
queryStringManager.listen((qs) => {
    console.log('a value is ' + qs.get('a'))
})
 
queryStringManager.push('a', 'foo')
//=> 'first call'
//=> 'a value is foo'

.parse( string )

just like it sound - parse the query-string and returns an object

.stringify( [queryStringObj] )

if nothing or null is passed to the argument this will stringifiy the current state of the object.

if passed an object it will return the query-string of the object that was passed

reset( [push = true] )

clear all the state object. and has the option to pushToUrl()

remove( string, [ push = true ] )

work just like lodash unset method works. and has the option to pushToUrl()

Contribute

So... it will be nice to have some help 💗

  1. Tests, tests and more tests
  2. better documentation (my english is not perfect)
  3. anything else that you think can be nice for this project
