tar-files

convenience wrapper around fs gunzip and node-tar to stream file entries' data.

var te = require('tar-files')
var eos = require('end-of-stream')

// the first argument may be a file name or a readable stream.

te('package.tar',function(stream,cb){
  if(stream.path === "package/README.md") {
    eos(stream.pipe(fs.createWriteStream('./tar-README.md')),cb)
  } else {
    // skip this entry
    cb();
  }
},function(err){
  
  // all done!

})

this example saves the README.md file from package.tar to the file ./tar-README.md

• works with gzipped or not compressed tars.

• pass in a stream or a file name
