seek-bzip

What is seek-bzip?

The seek-bzip npm package is a pure-Javascript implementation of the BZIP2 decompression algorithm, which allows for random access seeking within bzip2 files. This package is particularly useful for applications that need to extract portions of large compressed files without having to decompress the entire file.

What are seek-bzip's main functionalities?

Random Access Decompression

This feature allows users to decompress a specific block of data from a bzip2 compressed file, starting at a specified byte. This is useful for extracting data from large files without the need to decompress the entire file.

const fs = require('fs');
const seekBzip = require('seek-bzip');
const compressedData = fs.readFileSync('path/to/compressed-file.bz2');
const start = 12345; // start byte for decompression
const decompressedData = seekBzip.decodeBlock(compressedData, start);

Other packages similar to seek-bzip

unbzip2-stream

unbzip2-stream is a streaming bzip2 decompressor in pure JavaScript for Node.js. Unlike seek-bzip, it does not support random access seeking, but it is useful for streaming decompression of bzip2 files.

compressjs

compressjs is a collection of pure JavaScript implementations of various data compression algorithms, including bzip2. It provides a broader range of compression algorithms compared to seek-bzip, but it may not support random access seeking within bzip2 files.

node-bzip

node-bzip is a bzip2 compression and decompression library for Node.js. It is a wrapper around the C++ libbz2 library, which means it is not pure JavaScript like seek-bzip. It offers fast performance but does not support random access seeking.
