Usage

import { stringify, parse } from "superqs";

// Create a value of any type. This example uses an object, although any value
// can be used.
const data = {
  bool: true,
  undef: undefined,
  nullVal: null,
  date: new Date(),
  hugeNum: 0xffffffffffffffffffffn,
  bin: new Uint8Array([42, 24]),
};

// Create a URL-safe string representing the data above.
const stringifiedData = stringify(data);

// Use the stringified data to construct a URL.
const url = new URL(`https://example.com?data=${stringifiedData}`);

// Reconstruct the original data.
const params = new URLSearchParams(url.search);
const stringifiedDataParam = params.get("data");
const parsedData = parse(stringifiedDataParam);

// The `data` and `parsedData` values are equal.
expect(parsedData).toEqual(data); // true
