Advanced tools
Package description
The bson npm package is a library that allows you to serialize and deserialize data in BSON format. BSON, short for Binary JSON, is a binary-encoded serialization of JSON-like documents. It is designed to be efficient in both storage space and scan-speed. The bson package is commonly used when working with MongoDB, as MongoDB uses BSON as its document storage format.
Serialization
This feature allows you to convert a JavaScript object into a BSON formatted buffer. This is useful for storing and transmitting data in a compact binary form.
{"const BSON = require('bson'); const bson = new BSON(); const doc = { hello: 'world' }; const data = bson.serialize(doc); console.log(data); // <Buffer 16 00 00 00 02 68 65 6c 6c 6f 00 06 00 00 00 77 6f 72 6c 64 00 00>"}Deserialization
This feature allows you to convert BSON data back into a JavaScript object. This is useful when you need to read data that was stored or transmitted in BSON format.
{"const BSON = require('bson'); const bson = new BSON(); const data = Buffer.from('160000000268656c6c6f0006000000776f726c640000', 'hex'); const doc = bson.deserialize(data); console.log(doc); // { hello: 'world' }"}msgpack5 is a package that implements the MessagePack serialization format. MessagePack is an efficient binary serialization format that is similar to BSON but is not tied to MongoDB. It aims to be more compact and faster than JSON.
protobufjs is a package that allows you to serialize and deserialize data using Google's Protocol Buffers. Protocol Buffers are similar to BSON in that they provide a way to encode structured data in an efficient binary format, but they require a predefined schema and are more focused on cross-language compatibility.
cbor is a package that implements the CBOR (Concise Binary Object Representation) data format. Like BSON, CBOR is a binary format that can serialize and deserialize JavaScript objects. However, CBOR is designed to be more compact and to have a wider range of data types than BSON.
