json-pack-gzip

A module for compressing and decompressing JSON data using Gzip compression algorithm and HPack compression algorithm.

Installation

Use the package manager npm to install json-pack-gzip.

npm install json-pack-gzip

Usage

const jsonPackGzip = require('json-pack-gzip');

// Compress JSON data
const compressedData = jsonPackGzip.compress(jsonObject);

// Decompress JSON data
const decompressedData = jsonPackGzip.decompress(jsonBuffer);

// Calculate byte length of data
const byteLength = jsonPackGzip.calculateSize(data);

API

compress(jsonObject, debug = false)

Compresses a JSON object using Gzip compression algorithm. The input JSON object is first packed into a homogeneous array and then stringified before compression.

• jsonObject(Array): The JSON object to be compressed.
• debug(Boolean): options for debugging, defaults to false.

Returns a compressed data as a Buffer object.

decompress(jsonBuffer, debug = false)

Decompresses a Buffer object to a JSON object using Gzip decompression algorithm. The decompressed data is first parsed from a homogeneous array into a list of objects.

• jsonBuffer (Buffer): The Buffer object to be decompressed.
• debug(Boolean): options for debugging, defaults to false.

Returns a decompressed and unpacked JSON object as a list of objects.

calculateSize(data)

Calculates the byte length of the input data. It supports data types: String, Buffer, Array, and Object. For non-buffer objects, the function first stringifies them before calculating the size.

• data (String|Buffer|Object|Array): The data to be size-calculated.

Returns the byte length of the input data.
