url-query-json-parser

This module allows you to convert complex JSON object with deeply nested objects and arrays into a query string. On the other hand it converts the query string back into a JSON object with the same conditions while parsing numbers, arrays and booleans.

Install

$ npm install url-query-json-parser

$ yarn add url-query-json-parser

Usage

import urlQueryJsonParser from "url-query-json-parser";

const complexJson = {
  order: [
    {
      crop: {
        width: 300,
        height: 300,
      },
    },
  ],
  resize: {
    width: 100,
  },
  format: {
    ext: "jpeg",
    quality: "auto",
    progressive: true,
  },
};

const urlQuery = urlQueryJsonParser.parseJSON(complexJson);
console.log(urlQuery);
//=> "order[0][crop][width]=300&order[0][crop][height]=300&resize[width]=100&format[ext]=jpeg&format[quality]=auto&format[progressive]=TRUE"

const urlJson = urlQueryJsonParser.parseQuery(urlQuery);
console.log(JSON.stringify(urlJson));
//=> {"order":[{"crop":{"width":300,"height":300}}],"resize":{"width":100},"format":{"ext":"jpeg","quality":"auto","progressive":true}}
