JSONPatch

A library for parsing and evaluating JSONPatch files on JSON data objects.

It deviates from the spec to add support for additional features, but seeks to otherwise be fully compatible with JSONPatch data that is compliant with RFC6902.

Additional features include:

• The ability to test that a key exists by omitting value from the test operation.
• The ability to invert a test by providing "inverse": true in the test operation.
• The ability to provide a batch of JSONPatches to evaluate one at a time, gracefully skipping the patches containing a failed operation.
• The ability to use JSONPath for the path argument, instead of only supporting JSONPointer values.

Example

import json.patch.JSONPatch;

var patch = [
    {"op": "add", "path": "/a/d", "value": "e"}
];
var data = {"a": {"b": "c"}}

// {"a": {"b": "c", "d": "e"}}
trace(JSONPatch.applyPatches(patch, data));

// JSONPath is also supported.
var patch = [
    {"op": "replace", "path": "$..c", "value": 3}
];
var data = {"a": {"c": 11}, "b": {"c": 12}};

// {"a": {"c": 3 }, "b": { "c": 3 }}}
trace(JSONPatch.applyPatches(patch, data));
