There are some untar libraries, but I cannot get them working.
My idea would be something like
untar(bufferStreamOrFilePath).extractToDirectory("/path", function(err){})
Is something like this available?
The tar-stream module is a pretty good one:
var tar = require('tar-stream')
var extract = tar.extract();
extract.on('entry', function(header, stream, callback) {
// make directories or files depending on the header here...
// call callback() when you're done with this entry
});
fs.createReadStream("something.tar").pipe(extract)
extract.on('finish', function() {
console.log('done!')
});
Just an update on this answer, instead of node-tar, consider using tar-fs which yields a significant performance boost, as well as a neater interface.
var tarFile = 'my-other-tarball.tar';
var target = './my-other-directory';
// extracting a directory
fs.createReadStream(tarFile).pipe(tar.extract(target));
