JSON→URL

About

RFC8259 describes the JSON data model and interchange format, which is widely used in application-level protocols including RESTful APIs. It is common for applications to request resources via the HTTP POST method, with JSON entities. However, POST is suboptimal for requests which do not modify a resource's state. JSON→URL defines a text format for the JSON data model suitable for use within a URL/URI.

Usage

JSON→URL is available as a commonjs module (suitable for use in Node), ES6 module, or a script that may be used directly in a browser.

NPM install

npm install @jsonurl/jsonurl --save

CJS

const JsonURL = require("@jsonurl/jsonurl");

ES6 (Node + Babel)

import JsonURL from "@jsonurl/jsonurl";

Browser script tag

<script
    src="https://cdn.jsdelivr.net/npm/@jsonurl/[email protected]"
    integrity="sha512-PgDMK2pu/5iHU+sUvfCWIKugVg2NLSN1jmQJyJKbQw1MZAMvrU7XX3fPv4FJXgGBxTCsDnjhMmlZK5pzgPndTQ=="
    crossorigin="anonymous"></script>

The JavaScript API

Once included, the API is the same for all three.

let value = JsonURL.parse( "(Hello:World!)" );
let string = JsonURL.stringify( value );

If you intend to use JSON→URL inside a browser's address bar then you'll want to enable the AQF (address bar query string friendly) syntax.

let value = JsonURL.parse( "(Hello:Address Bar!!)",  { AQF: true });
let string = JsonURL.stringify( value,  { AQF: true } );

There are additional options available, but that's all you need to get started.

JSON→URL has no runtime dependencies.

Security

The parser is designed to parse untrusted input. It supports limits on the number of parsed values and depth of nested arrays or objects. When the limit is exceeded an Error is thrown, and reasonable limit values are set by default.
