What is JSON Patching?

JSON Patching is a standardized method defined in RFC 6902 for updating parts of a JSON document. Instead of replacing an entire JSON object, you can modify, add, remove, or replace specific fields or values. JSON Patching is commonly used in APIs and applications for efficient data manipulation.

Sample JSON Patch (RFC 6902)

A JSON Patch is an array of operations that describe changes to be applied to a JSON document. Each operation has the following structure:

[
  {
    "op": "replace",
    "path": "/name",
    "value": "Updated Name"
  },
  {
    "op": "add",
    "path": "/newField",
    "value": "New Value"
  },
  {
    "op": "remove",
    "path": "/unwantedField"
  }
]
          
  • op: The operation to perform (e.g., add, remove, replace).
  • path: The JSON Pointer path to the target field.
  • value: The new value to add or replace (optional for "remove").

This sample demonstrates replacing a value, adding a new field, and removing an unwanted field.
