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;
    }
