Status In Development

A Node.js unzip library

• Zero dependencies.

• Uncompresses Deflate archives ( default for most zip libraries ).

• Provides a directory listing of archive.

• Selectively inflate individual items.

• Does not verifiy size or calculate CRC32 of artifacts.

Examples

Simplest extraction:

  const { unzip } = require( '@hiteshlala/unzippy' );

  const source = 'path_some_zip_archive.zip';
  const dest = 'path_to_place_to_write_artifacts';

  unzip(  source, out )
  .then( console.log )
  .catch( console.error );

Add more options:

  const { Unzippy } = require( '@hiteshlala/unzippy' );

  const source = 'path_some_zip_archive.zip';
  const dest = 'path_to_place_to_write_artifacts';

  // instantiate archive
  const z = new Unzippy({ 
    src: source, 
    dest: out
  });

  // get a directory listing
  const dir = z.getDir(); // returns an array
  console.log( dir.map( i => i.fName ) );

  // extract a single file - select by index of dir array
  z.extractSingle( 3 )
  .then( console.log )
  .catch( console.error );

  // extract entire directory
  z.unzip()
  .then( console.log )
  .catch( console.error );

API

Class Unzippy

• new Unzippy( options )

  • Takes an options object:

    {
      src: < String: path to source archive >,
      dest: < String: path to where to unzip >,
    
      // planned options to come in future release:
      // logfile: < Boolean: create a log file>
      // verbose: < Allow logging to console >
    
    }

• .getDir()

  • Returns an Array containing an Object for each artifact in archive.

• .extractSingle( id )

  • Extracts a single artifact and returns a Promise.

• .unzip()

  • Extracts all artifacts and returns a Promise.

unzip

• unzip( src, dest )

  • src - path to source archive

  • dest - path to where to unzip
