It is streams2 and operates purely using streams which means you can easily extract/parse tarballs without ever hitting the file system. - -Note that you still need to gunzip your data if you have a `.tar.gz`. We recommend using [gunzip-maybe](https://github.com/mafintosh/gunzip-maybe) in conjunction with this. - -``` -npm install tar-stream -``` - -[](http://travis-ci.org/mafintosh/tar-stream) -[](http://opensource.org/licenses/MIT) - -## Usage - -tar-stream exposes two streams, [pack](https://github.com/mafintosh/tar-stream#packing) which creates tarballs and [extract](https://github.com/mafintosh/tar-stream#extracting) which extracts tarballs. To [modify an existing tarball](https://github.com/mafintosh/tar-stream#modifying-existing-tarballs) use both. - - -It implementes USTAR with additional support for pax extended headers. It should be compatible with all popular tar distributions out there (gnutar, bsdtar etc) - -## Related - -If you want to pack/unpack directories on the file system check out [tar-fs](https://github.com/mafintosh/tar-fs) which provides file system bindings to this module. - -## Packing - -To create a pack stream use `tar.pack()` and call `pack.entry(header, [callback])` to add tar entries. - -``` js -var tar = require('tar-stream') -var pack = tar.pack() // pack is a streams2 stream - -// add a file called my-test.txt with the content "Hello World!" -pack.entry({ name: 'my-test.txt' }, 'Hello World!') - -// add a file called my-stream-test.txt from a stream -var entry = pack.entry({ name: 'my-stream-test.txt', size: 11 }, function(err) { - // the stream was added - // no more entries - pack.finalize() -}) - -entry.write('hello') -entry.write(' ') -entry.write('world') -entry.end() - -// pipe the pack stream somewhere -pack.pipe(process.stdout) -``` - -## Extracting - -To extract a stream use `tar.extract()` and listen for `extract.on('entry', (header, stream, next) )` - -``` js -var extract = tar.extract() - -extract.on('entry', function(header, stream, next) { - // header is the tar header - // stream is the content body (might be an empty stream) - // call next when you are done with this entry - - stream.on('end', function() { - next() // ready for next entry - }) - - stream.resume() // just auto drain the stream -}) - -extract.on('finish', function() { - // all entries read -}) - -pack.pipe(extract) -``` - -The tar archive is streamed sequentially, meaning you **must** drain each entry's stream as you get them or else the main extract stream will receive backpressure and stop reading. - -## Headers - -The header object using in `entry` should contain the following properties. -Most of these values can be found by stat'ing a file. - -``` js -{ - name: 'path/to/this/entry.txt', - size: 1314, // entry size. defaults to 0 - mode: 0644, // entry mode. defaults to to 0755 for dirs and 0644 otherwise - mtime: new Date(), // last modified date for entry. defaults to now. - type: 'file', // type of entry. defaults to file. can be: - // file | link | symlink | directory | block-device - // character-device | fifo | contiguous-file - linkname: 'path', // linked file name - uid: 0, // uid of entry owner. defaults to 0 - gid: 0, // gid of entry owner. defaults to 0 - uname: 'maf', // uname of entry owner. defaults to null - gname: 'staff', // gname of entry owner. defaults to null - devmajor: 0, // device major version. defaults to 0 - devminor: 0 // device minor version. defaults to 0 -} -``` - -## Modifying existing tarballs - -Using tar-stream it is easy to rewrite paths / change modes etc in an existing tarball. - -``` js -var extract = tar.extract() -var pack = tar.pack() -var path = require('path') - -extract.on('entry', function(header, stream, callback) { - // let's prefix all names with 'tmp' - header.name = path.join('tmp', header.name) - // write the new entry to the pack stream - stream.pipe(pack.entry(header, callback)) -}) - -extract.on('finish', function() { - // all entries done - lets finalize it - pack.finalize() -}) - -// pipe the old tarball to the extractor -oldTarballStream.pipe(extract) - -// pipe the new tarball the another stream -pack.pipe(newTarballStream) -``` - -## Saving tarball to fs - - -``` js -var fs = require('fs') -var tar = require('tar-stream') - -var pack = tar.pack() // pack is a streams2 stream -var path = 'YourTarBall.tar' -var yourTarball = fs.createWriteStream(path) - -// add a file called YourFile.txt with the content "Hello World!" -pack.entry({name: 'YourFile.txt'}, 'Hello World!', function (err) { - if (err) throw err - pack.finalize() -}) - -// pipe the pack stream to your file -pack.pipe(yourTarball) -
