BSON Libraries

Most of these libraries use the Apache 2 license, but check individual project details to confirm.

• AssemblyScript

  • assemblyscript-bson - BSON encoder / decoder library written in AssemblyScript, compiles to WebAssembly. Can be used to enable transfer of complex objects between JavaScript and WebAssembly. Originally written to support smart contract development in WebAssembly.

• C

  • libbson - A library providing useful routines related to building, parsing, and iterating BSON documents. Used by the cross-platform libmongoc client library that provides a base for MongoDB drivers in higher-level languages.

  • Mongo-GLib - A library written in C to communicate with the MongoDB database in an asynchronous fashion. Even though the library is written in C, it can be used from higher level libraries such as Python and JavaScript through the use of GObject introspection.

• C# / .NET

  • Newtonsoft.Json.Bson - Adds support for reading and writing BSON to the popular Json.NET library.

  • MongoDB.Bson - Included with the official MongoDB C#/.NET driver.

  • Metsys.Bson - A BSON serializer/deserializer for .NET.

• C++

  • The MongoDB C++ Driver Library - The official MongoDB C++ driver includes a robust and well tested BSON implementation. You can use just the BSON portion of the driver library if desired.

  • github.com/jbenet/bson-cpp - A standalone C++ BSON implementation forked from the MongoDB C++ driver, with the non-BSON code pruned away.

  • github.com/dwight/bson-cxx - Yet another C++ BSON implementation originating from the MongoDB C++ driver. Non-BSON code was eliminated, Endian-awareness was added, and some attempts were made to simplify the interface.

  • JSON for Modern C++ - A library to make JSON a first-class data type in C++ which can read and write a subset of BSON that can map to JSON.

  • oatpp-mongo - BSON object-mapper plus MongoDB driver for Oat++ applications.

  • jsoncons - A C++ header-only library for constructing JSON and JSON-like data formats including BSON, supports encode/decode of BSON byte string.

  • reflect-cpp - A C++-20 library that provides a unified reflection-based interface for various serialization formats, including BSON.

• D

  • vibe.data.bson - BSON serialization and value handling.

• Dart

  • bson_codec - A flexible serializer and deserializer for BSON documents.

• Delphi

  • DynamicDataObjects - Supports JSON, MessagePack, CBOR, CSV, BinaryJData, ICS, Smile, ION, UBJSON, and DDO. It includes tools for command-line conversion between formats, a windows app for editing and diffing these file types, and an explorer previewer plugin.
