JSON Pointer

This is an implementation of RFC-6901 JSON Pointer. JSON Pointer is designed for referring to data values within a JSON document. It's designed to be URL friendly so I can be used as a URL fragment that points to a specific part of the JSON document.

Installation

npm install @hyperjump/json-pointer --save

Usage

import * as JsonPointer from "@hyperjump/json-pointer";

const value = {
  "foo": {
    "bar": 2
  }
};

JsonPointer.get(value, "/foo/bar"); // 2
JsonPointer.append("/foo", "bar"); // "/foo/bar"
JsonPointer.cons("foo", JsonPointer.nil); // "/foo"
JsonPointer.decons("/foo/bar"); // ["foo", "/bar"]
