Usage

Deserialize and apply immediately:

var patch = JsonSerializer.Deserialize<JsonPatch>(patchString);
var doc = JsonNode.Parse(docString);
var result = patch.Apply(doc);

Or you can build a patch inline:

var patch = new JsonPatch(PatchOperation.Add("/foo/bar", "baz"),
 PatchOperation.Test("/foo/biz", false));

There is also limited patch generation support:

// parse your data
var start = JsonNode.Parse("[{\"test\":\"test123\"},{\"test\":\"test321\"},{\"test\":[1,2,3]},{\"test\":[1,2,4]}]");
// or build it inline
var target = new JsonArray{
 new JsonObject { ["test"] = "test123" },
 new JsonObject { ["test"] = "test32132" },
 new JsonObject { ["test1"] = "test321" },
 new JsonObject { ["test"] = new JsonArray{ 1, 2, 3 } },
 new JsonObject { ["test"] = new JsonArray{ 1, 2, 3 } },
}

var patch = start.CreatePatch(target);

/*
Result:
[
 {"op":"replace","path":"/1/test","value":"test32132"},
 {"op":"remove","path":"/2/test"},
 {"op":"add","path":"/2/test1","value":"test321"},
 {"op":"replace","path":"/3/test/2","value":3},
 {"op":"add","path":"/4","value":{"test":[1,2,3]}}
]
