node-rar

Native NodeJS rar addon.

This library is inspired by https://github.com/davidcroda/node-rar and the original library. I needed a native unrar addon that worked with the new versions of node. I also updated the addon to be able to process an archive asynchronously.

Install

npm install @fknop/node-unrar

It's published under the @fknop scope to avoid using a name like node-unrar2 or something like that.

API

OpenMode

• List = 0,
• Extract = 1

RarResult

• name: the archive name
• files: an array of files in the archive (see RarOptions.humanResults for more details)

RarOptions

• openMode: the archive open mode
• dest: the destination directory for extraction (ignored in list mode).
• password: the archive password
• humanResults: instead of an array of raw string names, display the files as a tree

Without humanResults:

{
  name: 'archive.rar',
  files: [
    'dir',
    'dir/file1',
    'dir/file2',
    'dir/file3',
    'dir/dir2/file4',
    'dir/dir2/file5',
    'file'
  ]
}

With humanResults:

{
  name: 'archive.rar',
  files: {
    'dir': {
      'file1': {},
      'file2': {},
      'file3': {},
      'dir2': {
        'file4': {},
        'file5': {}
      }
    },
    'file': {}
  }
}

RarCallback

RarCallback is a simple node callback (err, results) => { ... }.

processArchive(path: string, options?: RarOptions|RarCallback, cb?: RarCallback): Promise<RarResult>|void

Process an archive asynchronously. By default, it lists files.

• path: the path of the archive
• options: The options, or the callback if no options are needed
• cb: the callback if options are needed

If no callback is provided, a promise will be returned.

list(path: string, options?: RarOptions|RarCallback, cb?: RarCallback): Promise<RarResult>|void

Alias for processArchive with OpenMode.List.

extract(path: string, options?: RarOptions|RarCallback, cb?: RarCallback): Promise<RarResult>|void

Alias for processArchive with OpenMode.Extract.

processArchiveSync(path: string, options?: RarOptions): RarResult

Process an archive synchronously. By default, it lists files. If an error occurs, it will throw an exception.

listSync(path: string, options?: RarOptions): RarResult

Alias for processArchiveSync with OpenMode.List.

extractSync(path: string, options?: RarOptions): RarResult

Alias for processArchiveSync with OpenMode.Extract.
