The official BSON (Binary JSON) parser library for Node.js and browsers, maintained by MongoDB. It serializes and deserializes JSON-like documents to and from the BSON binary format, including types like ObjectId, and supports EJSON stringification.

Use cases

• serialize documents to bson binary format
• deserialize bson bytes back into javascript objects
• work with mongodb objectid and extended
• parse bson data in the browser
• encode -like documents for storage or network transfer

When to choose

• you need to encode or decode BSON, e.g. when working with MongoDB data directly
• you need BSON support in both Node.js and browser environments
• you need EJSON (Extended JSON) serialization of MongoDB-specific types

When to avoid

• you just need plain JSON serialization with no binary format requirements
• you are using a MongoDB driver, which already bundles BSON internally
• you need a human-readable data interchange format rather than binary
