System Text Json Patch

SystemTextJsonPatch is a JSON Patch (JsonPatchDocument) RFC 6902 implementation for .NET using System.Text.Json

This library tries to ease the migration from Newtonsoft.Json to System.Text.Json by providing similar API for HttpPatch requests as in Microsoft.AspNetCore.JsonPatch and Marvin.JsonPatch

  • Designed as an easy replacement for Microsoft.AspNetCore.JsonPatch
  • Supports .NET 6+ & netstandard2.0

Getting started

Build a patch document on the client. You can use the operations as described in the IETF document: Add, Remove, Replace, Copy, Move and Test.

JsonPatchDocument<DTO.Expense> expensePatch = new JsonPatchDocument<DTO.Expense>();
expensePatch.Replace(e => e.Description, expense.Description);

// serialize it to JSON
var expensePatchJson = System.Text.Json.JsonSerializer.Serialize(expensePatch);

On your API, in the patch method (accept document as parameter & use ApplyTo method)

public IHttpActionResult Patch(
    int id,
    [FromBody] JsonPatchDocument<DTO.Expense> expensePatchDocument
      // get the expense from the repository
      var expense = _repository.GetExpense(id);

      // apply the patch document 

      // changes have been applied to expense object

Migration from v1

JsonPatchDocumentConverterFactory no longer needs to be set to JsonSerializerOptions. Instead JsonPatchDocument types now use JsonConvertAttribute to use the correct converter.

Performance comparison

This test deserializes a JSON patch document of 8 operations and applies the changes to a new model.

See SystemTextJsonPatch.Benchmark for more details.
