Not supported, never supported. Take a look at compressjs, which incorporates some part of node-bzip.

node-bzip is a pure-javascript Node.JS module adapted from antimatter15's pure-javascript implementation for decoding bzip2 data. node-bzip currently only decodes buffers into other buffers, synchronously.

How to Install

npm install node-bzip


After compressing some example data into example.bz2, the following with recreate that original data and save it to example.

var decodeBzip = require('node-bzip');
var fs = require('fs');
var compressedData = fs.readFileSync('example.bz2');
var data = decodeBzip(compressedData);
fs.writeFileSync('example', data);


require('node-bzip') returns a function accepting one or two parameters:

function decodeBzip(Buffer inputBuffer, [Number expectedSize])

If expectedSize is not present, decodeBzip simply decodes inputBuffer and returns the resulting Buffer.

If expectedSize is present, decodeBzip will store the results in a Buffer of length expectedSize, and throw an error in the case that the size of the decoded data does not match expectedSize.


Please note that this module is almost entirely untested and should not be used in a production environment!
