@types/bson

What is @types/bson?

@types/bson provides TypeScript type definitions for the BSON library, which is used for serializing and deserializing data in the BSON (Binary JSON) format. This is particularly useful when working with MongoDB, as BSON is the format used for storing documents in MongoDB.

What are @types/bson's main functionalities?

Serialize an Object to BSON

This feature allows you to serialize a JavaScript object into BSON format. The serialized data can then be stored or transmitted in a binary format.

const BSON = require('bson');
const bson = new BSON();
const obj = { name: 'John', age: 30 };
const data = bson.serialize(obj);
console.log(data);

Deserialize BSON to an Object

This feature allows you to deserialize BSON data back into a JavaScript object. This is useful for reading data that was previously serialized into BSON format.

const BSON = require('bson');
const bson = new BSON();
const data = Buffer.from([/* some BSON data */]);
const obj = bson.deserialize(data);
console.log(obj);

ObjectId Generation

This feature allows you to generate a new ObjectId, which is a unique identifier commonly used in MongoDB documents.

const BSON = require('bson');
const ObjectId = BSON.ObjectId;
const id = new ObjectId();
console.log(id.toHexString());

Other packages similar to @types/bson

bson

The 'bson' package is the core library for BSON serialization and deserialization. It provides the same functionalities as @types/bson but without TypeScript type definitions. It is often used directly in JavaScript projects.

mongodb

The 'mongodb' package is the official MongoDB driver for Node.js. It includes BSON serialization and deserialization functionalities along with a comprehensive API for interacting with MongoDB databases. It is more feature-rich compared to @types/bson, as it provides database connectivity and operations.

bson-ext

The 'bson-ext' package is an extension of the 'bson' library that includes native C++ bindings for improved performance. It offers the same BSON serialization and deserialization functionalities but is faster due to its native implementation.

README

This is a stub types definition for @types/bson (https://github.com/mongodb/js-bson#readme).

bson provides its own type definitions, so you don't need @types/bson installed!
