msgpackr

What is msgpackr?

The msgpackr npm package is a JavaScript library for serializing and deserializing data using the MessagePack binary format. It is designed to be fast and efficient, providing a compact binary representation of JSON-like data structures. This package can be used in both Node.js and browser environments.

What are msgpackr's main functionalities?

Serialization

Serialization is the process of converting a JavaScript object into a MessagePack binary buffer. This is useful for sending data over a network or storing it in a binary format.

{"const { pack } = require('msgpackr');\nconst packedData = pack({ hello: 'world' });\nconsole.log(packedData); // Outputs a Buffer or Uint8Array containing the serialized data"}

Deserialization

Deserialization is the process of converting a MessagePack binary buffer back into a JavaScript object. This is useful for reading data received over a network or from a binary storage format.

{"const { unpack } = require('msgpackr');\nconst packedData = new Uint8Array([0x82, 0xA5, 0x68, 0x65, 0x6C, 0x6C, 0x6F, 0xA5, 0x77, 0x6F, 0x72, 0x6C, 0x64]);\nconst data = unpack(packedData);\nconsole.log(data); // Outputs { hello: 'world' }"}

Stream Support

msgpackr provides stream support for both serialization and deserialization, allowing it to be integrated with Node.js streams for processing large amounts of data or data that is received over time.

{"const { PackrStream, UnpackrStream } = require('msgpackr');\nconst packrStream = new PackrStream();\nconst unpackrStream = new UnpackrStream();\n// Use the streams for packing and unpacking data with Node.js streams."}

Other packages similar to msgpackr

msgpack5

msgpack5 is another npm package that provides MessagePack serialization and deserialization. It is designed to be compliant with the latest MessagePack specification and offers a similar API to msgpackr. However, msgpackr may have performance advantages due to its focus on speed and efficiency.

protobufjs

protobufjs is an npm package that allows users to serialize and deserialize data using Protocol Buffers, which is a different binary serialization format developed by Google. While it serves a similar purpose to msgpackr, the two use different formats and protobufjs requires schema definitions for the data structures.

bson

bson is an npm package that provides serialization and deserialization for the BSON (Binary JSON) format. BSON is used by MongoDB and is similar to MessagePack in that it provides a binary representation of JSON-like data. msgpackr and bson offer similar functionalities, but they use different binary formats and may have different performance characteristics.
