Tar for Node.js.
|

|

[](https://nodei.co/npm/tar/)
|
||
|
|
|
||
|
|
## API
|
||
|
|
|
||
|
|
See `examples/` for usage examples.
|
||
|
|
|
||
|
|
### var tar = require('tar')
|
||
|
|
|
||
|
|
Returns an object with `.Pack`, `.Extract` and `.Parse` methods.
|
||
|
|
|
||
|
|
### tar.Pack([properties])
|
||
|
|
|
||
|
|
Returns a through stream. Use
|
||
|
|
[fstream](https://npmjs.org/package/fstream) to write files into the
|
||
|
|
pack stream and you will receive tar archive data from the pack
|
||
|
|
stream.
|
||
|
|
|
||
|
|
This only works with directories, it does not work with individual files.
|
||
|
|
|
||
|
|
The optional `properties` object are used to set properties in the tar
|
||
|
|
'Global Extended Header'. If the `fromBase` property is set to true,
|
||
|
|
the tar will contain files relative to the path passed, and not with
|
||
|
|
the path included.
|
||
|
|
|
||
|
|
### tar.Extract([options])
|
||
|
|
|
||
|
|
Returns a through stream. Write tar data to the stream and the files
|
||
|
|
in the tarball will be extracted onto the filesystem.
|
||
|
|
|
||
|
|
`options` can be:
|
||
|
|
|
||
|
|
```js
|
||
|
|
{
|
||
|
|
path: '/path/to/extract/tar/into',
|
||
|
|
strip: 0, // how many path segments to strip from the root when extracting
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
`options` also get passed to the `fstream.Writer` instance that `tar`
|
||
|
|
uses internally.
|
||
|
|
|
||
|
|
### tar.Parse()
|
||
|
|
|
||
|
|
Returns a writable stream. Write tar data to it and it will emit
|
||
|
|
`entry` events for each entry parsed from the tarball. This is used by
|
||
|
|
`tar.Extract`.
