JarCastingqss 
A tiny (305B) browser utility for stringifying a query Object.
You should only consider using this within a browser context since Node's built-in querystring.stringify is much faster and should be used in a Node environment! An ideal use case is serializing a query object before an API request is sent.
This module exposes three module definitions:
- ES Module:
dist/qss.mjs - CommonJS:
dist/qss.js - UMD:
dist/qss.min.js
Install
$ npm install --save qss
Usage
import { encode, decode } from 'qss';
encode({ foo:'hello', bar:[1,2,3], baz:true });
//=> 'foo=hello&bar=1&bar=2&bar=3&baz=true'
encode({ foo:123 }, '?');
//=> '?foo=123'
encode({ bar:'world' }, 'foo=hello&');
//=> 'foo=hello&bar=world'
decode('foo=hello&bar=1&bar=2&bar=3&baz=true');
//=> { foo:'hello', bar:[1,2,3], baz:true };
API
qss.encode(params, prefix)
Returns: String
Returns the formatted querystring.
params
Type: Object
The object that contains all query parameter keys & their values.
prefix
Type: String
Default: ''
An optional prefix. The stringified params will be appended to this value, so it must end with your desired joiner; eg ?.
Important: No checks or validations will run on your
prefix. Similarly, no character is used to "glue" the query string to yourprefixstring.
qss.decode(query)
Returns: Object
Returns an Object with decoded keys and values.
Repetitive keys will form an Array of its values. Also, qss will attempt to typecast Boolean and Number values.
query
Type: String
The query string, without its leading ? character.
qss.decode(
location.search.substring(1) // removes the "?"
);
