How to use?

pack(from, to, names)

from - string directory that would be packed
to - string or stream, name of archive
names - array of names in directory from that would be packed.

const jaguar = require('jaguar');
const path = require('path');
const cwd = process.cwd();
const name = 'pipe.tar.gz';
const from = cwd + '/pipe-io';
const to = path.join(cwd, name);

const pack = jaguar.pack(from, to, [
    'LICENSE',
    'README.md',
    'package.json'
]);

pack.on('file', (name) => {
    console.log(name);
});

pack.on('start', () => {
    console.log('start of packing');
});

pack.on('progress', (percent) => {
    console.log(percent + '%');
});

pack.on('error', (error) => {
    console.error(error);
});

pack.on('end', () => {
    console.log('done');
});

extract(from, to)

from - path to .tar.gz archive
to - path to directory where files would be stored.

const jaguar = require('jaguar');
const path = require('path');
const cwd = process.cwd();
const name = 'pipe.tar.gz';
const to = cwd + '/pipe-io';
const from = path.join(cwd, name);

const extract = jaguar.extract(from, to);

extract.on('file', (name) => {
    console.log(name);
});

extract.on('progress', (percent) => {
    console.log(percent + '%');
});

extract.on('error', (error) => {
    console.error(error);
});

extract.on('end', () => {
    console.log('done');
});

In case of starting example output should be similar to:
