    I would personally recommend this awesome ES6 course by Wes Bos.


    Install

    $ npm install --save query-string
    

    Usage

    const queryString = require('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'

    API

    .parse(string)

    Parse a query string into an object. Leading ? or # are ignored, so you can pass location.search or location.hash directly.

    The returned object is created with Object.create(null) and thus does not have a prototype.

    .stringify(object, [options])

    Stringify an object into a query string, sorting the keys.

    strict

    Type: boolean
    Default: true

    Strictly encode URI components with strict-uri-encode. It uses encodeURIComponent if set to false. You probably don't care about this option.

    encode

    Type: boolean
    Default: true

    URL encode the keys and values.

    .extract(string)

    Extract a query string from a URL that can be passed into .parse().

    Nesting

    This module intentionally doesn't support nesting as it's not spec'd and varies between implementations, which causes a lot of edge cases.

    You're much better off just converting the object to a JSON string:

    queryString.stringify({
        foo: 'bar',
        nested: JSON.stringify({
            unicorn: 'cake'
        })
    });
    //=> 'foo=bar&nested=%7B%22unicorn%22%3A%22cake%22%7D'

    However, there is support for multiple instances of the same key:

    queryString.parse('likes=cake&name=bob&likes=icecream');
    //=> {likes: ['cake', 'icecream'], name: 'bob'}
     
    queryString.stringify({color: ['taupe', 'chartreuse'], id: '515'});
    //=> 'color=chartreuse&color=taupe&id=515'
