Welcome to Hyperbee Json

Hyperbee Json is a high-performance JSON library for .NET, providing robust support for JSONPath, JsonPointer, JsonPatch, and JsonDiff. This library is optimized for speed and low memory allocations, and it adheres to relevant RFCs to ensure reliable and predictable behavior.

Unlike other libraries that support only JsonElement or JsonNode, Hyperbee.Json supports both types, and can be easily extended to support additional document types and functions.

Features

High Performance: Optimized for performance and efficiency.
Low Memory Allocations: Designed to minimize memory usage.
Comprehensive JSON Support: Supports JSONPath, JsonPointer, JsonPatch, and JsonDiff.
Conformance: Adheres to the JSONPath Specification RFC 9535, JSONPointer RFC 6901, and JsonPatch RFC 6902.
Supports both JsonElement and JsonNode: Works seamlessly with both JSON document types.

JSONPath

JSONPath is a query language for JSON, allowing you to navigate and extract data from JSON documents using a set of path expressions. Hyperbee.Json's JSONPath implementation is designed for optimal performance, ensuring low memory allocations and fast query execution. It fully conforms to RFC 9535.

JSONPointer

JSONPointer is a syntax for identifying a specific value within a JSON document. It is simple and easy to use, making it an excellent choice for pinpointing exact values. Hyperbee.Json's JsonPointer implementation adheres to RFC 6901.

JSONPatch

JSONPatch is a format for describing changes to a JSON document. It allows you to apply partial modifications to JSON data efficiently. Hyperbee.Json supports JsonPatch as defined in RFC 6902, ensuring compatibility and reliability.

JSONDiff

JSONDiff allows you to compute the difference between two JSON documents, which is useful for versioning and synchronization. Hyperbee.Json's implementation is optimized for performance and low memory usage, adhering to the standards set in RFC 6902.

Getting Started

To get started with Hyperbee.Json, refer to the documentation for detailed instructions and examples.

You can intall the library via NuGet:

dotnet add package Hyperbee.Json
