Examples

Examples for the JSON Merge Patch (RFC 7386) implementation.

Quick Start

Choose an example to run:

go run ./examples/struct-merge
go run ./examples/map-merge
go run ./examples/json-string-merge
go run ./examples/json-bytes-merge

Example Structure

Each directory focuses on one document form:

• struct-merge — type-safe struct operations
• map-merge — dynamic map data operations
• json-string-merge — JSON string processing
• json-bytes-merge — JSON byte processing

Core Concepts

RFC 7386 Key Behaviors

1. Recursive object merging — nested objects are merged recursively.
2. null deletes fields — null values remove target fields.
3. Array replacement — arrays are replaced entirely, not element by element.
4. New field addition — new fields from the patch are added to the target.

Supported Document Types

• struct — type-safe documents converted through JSON
• map[string]any — dynamic object form
• string — valid JSON strings or raw string scalar values
• []byte — valid JSON byte slices
