hyperjump-io/json

A JSON parser and stringifier with JSON Pointer support

Json

This is a reimplementation of the builtin JSON object to add JSON Pointer parameters to the "reviver" and "replacer" functions. Other than the added parameters, the interface and behavior is the same as the original.

Installation

Includes support for node.js (ES Modules, TypeScript) and browsers.

npm install @hyperjump/json

Usage

import * as Json from "@hyperjump/json";

const subject = `{
  "type": "object",
  "properties": {
    "foo": { "type": "string" },
    "bar": { "$ref": "#/$defs/number" }
  },
  "required": ["foo", "bar"],

  "$defs": {
    "number": { "type": "number" }
  }
}`;
const result = Json.parse(subject, (key, value, pointer) => {
  console.log("REVIVER", pointer, key, JSON.stringify(value));
  return value;
});

const json = Json.stringify(result, (key, value, pointer) => {
  console.log("REPLACER", pointer, key, value);
  return value;
}, "  ");
