Simple tar.gz compression and decompression for NodeJS.

Installation

npm install targz

Simple Usage


var targz = require('targz');

// compress files into tar.gz archive
targz.compress({
    src: 'path_to_files',
    dest: 'path_to_compressed_file'
}, function(err){
    if(err) {
        console.log(err);
    } else {
        console.log("Done!");
    }
});

// decompress files from tar.gz archive
targz.decompress({
    src: 'path_to_compressed file',
    dest: 'path_to_extract'
}, function(err){
    if(err) {
        console.log(err);
    } else {
        console.log("Done!");
    }
});

Advanced Usage

You can adjust tar and gzip/gunzip parameters by using optional parameters. The API:


// Compress API
targz.compress( options, callback );

// Decompress API
targz.decompress( options, callback );

Where supported options are:

src - (String) The path to files to be compressed
dest - (String) The path to tar.gz file to be created
tar - (Object) Adjust tar options. See tar-fs docs for details. OPTIONAL.
- ignore - (Function) Ignore/filter files
- entries - (Array) Define list of files
- map - (Function) Modify the headers
- mapStream - (Function) Modify the input/output file streams
- dmode - (Number) Set the permissions for directories
- fmode - (Number) Set permissions for files
- strict - (Boolean) Ignore errors due to unsupported entry types (like device files). Default: true
- dereference - (Boolean) Pack the contents of the symlink instead of the link itself. Default: false
gz - (Object) Adjust gzip/gunzip options. See zlib docs for details. OPTIONAL.

Example


var targz = require('targz');

// compress files into tar.gz archive while filtering all .bin files and having gzip level/memLevel set to 6
targz.compress({
    src: 'path_to_files',
    dest: 'path_to_compressed_file',
    tar: {
        ignore: function(name) {
            return path.extname(name) === '.bin' // ignore .bin files when packing
        }
    },
    gz: {
        level: 6;
        memLevel: 6;
    }
}, function(err){
    if(err) {
        console.log(err);
