API

• extractFromFile extracts a tarball file into a target directory.

// Specify a file and target directory
unpacker
  .extractFromFile('/path/to/file.tgz', '/tmp/destination')

    console.log('Done!')
  })

Listen to each file extracted:

import unpacker from 'tarball-unpacker'

unpacker
  .configure({
    silent: true,
    onExtract: (entry) => {
      console.log(entry.path)
    }
  })
  .extractFromFile('/path/to/file.tgz', '/tmp/destination')
  .then(() => {
    console.log('Done!')
  })
  .catch((err) => {
    console.log('Something went wrong ', err)
  })

    console.log(files) // An array of unpacked paths to files
    console.log('Done!')
  })
  .catch((err) => {
    console.log('Something went wrong ', err)
  })
