tar.gz

node-tar.gz

Native gzip compression and decompression utility for Node.js.

Installation

For simple installation:

npm install tar.gz

If you want to use the targz command line:

npm intall -g tar.gz

Usage

At the moment this package can only compress a folder and everything that is inside it. To compress something is easy:

var targz = require('tar.gz');
var compress = new targz().compress('/path/to/compress', '/path/to/store.tar.gz', function(err){
    if(err)
        console.log(err);

    console.log('The compression has ended!');
});

With the same easy you can extract a gziped file:

var targz = require('tar.gz');
var compress = new targz().extract('/path/to/stored.tar.gz', '/path/to/extract', function(err){
    if(err)
        console.log(err);

    console.log('The extraction has ended!');
});

You can pass some configuration parameters to the constructor before compress:

var targz = require('tar.gz');
var compress = new targz({
    level : 6 //the compression level from 0-9, default: 6
    memLevel : 6 //the memory allocation level from 1-9, default: 6
    proprietary : false //to include or not proprietary headers, default: true
});

Command line

$ targz -h

  Usage: targz [options]

  Options:

    -h, --help           output usage information
    -V, --version        output the version number
    -c, --compress       Compress folder to archive
    -x, --extract        Extract archive to folder
    -l, --level [n]      Compression level from 0-9. Default 6.
    -m, --memory [n]     Memory allocation level from 1-9. Default 6.
    -n, --noproprietary  Remove proprietary headers.

  Examples:

    $ targz -c /folder/to/compres /path/to/archive.tar.gz

    $ targz -x /path/to/archive.tar.gz /destination/folder

    Maximum compression
    $ targz -l 9 -m 9 -c /folder/to/compres /path/to/archive.tar.gz
