JSON Patch is a tool for making precise updates to JSON documents without rewriting everything from scratch.It allows defining operations like adding a key, replacing a value, or removing a field in a compact, reusable way.The json-patch library supports both JSON Patch (RFC 6902) for precise updates and JSON Merge Patch (RFC 7396) for whole-document changes.JSON Patch is crucial for handling large JSON files, such as those generated by Language Models (LLMs) with output limits.You can efficiently stitch together multiple JSON chunks from LLM outputs using JSON Patch.Setting up and configuring the json-patch library involves adjusting global settings and using ApplyWithOptions for more control.You can patch LLM output chunks into one JSON document by applying operations like add, replace, or remove.JSON Patch is useful for scenarios like syncing client-server updates and combining multiple patches in a controlled manner.Tips for smoother patching include validating patches, testing equality, handling missing paths, and using the json-patch CLI for testing.By leveraging JSON Patch and understanding its operations, you can effectively manage and manipulate JSON data for various applications.
