JSON util – Build Coverage

JSON Pointer RFC 6901 and JSON Merge Patch RFC 7396 implementation. The main goal is to have a small and reasonably fast code.

When used directly with script tag, methods are added to global JSON object.

When used with require, methods are exported as expected.

Examples

var util = require("json-util")
, obj = {"a": {"b": 1}}

// get a value
var b = util.pointer(obj, "/a/b")
// b is 1

// set a value
var oldValue = util.pointer(obj, "/a/b", 2) // sets value to 2
// oldValue is 1

// adding to a nonexistent target will create missing object literals
util.pointer(obj, "/a/c/d/e", "3")
// obj is now {"a": {"b": 2, "c": {"d": {"e": "3"}}}}

// apply a patch and collect JSON Pointers to array that were changed
var changed = []
util.mergePatch(obj, {"a": {"c": "C"}}, changed /* optional */)
// obj is now {"a": {"b": 2, "c": "C"}}
// changed = ["/a", "/a/c"]

// test is it a object literal
json.isObject(obj)
// true
