Question

Would like to know how to extract tbz file with Node JS and save to disk. Sample code would be very appreciated.

Tried with something like this:

var zlib = require('zlib');
var fs = require('fs');

var file = fs.createReadStream('/tmp.tbz');
var zip = file.pipe(zlib.createUnzip());

zip.on("data", function(data) {
  console.log(data);
});

zip.on("error",function(error){
    console.log(error);
});

But end up with:

{ [Error: incorrect header check] errno: -3, code: 'Z_DATA_ERROR' } 

Not sure I did this correctly.

Answer 1

Didn’t manage to find node library for extracting the tbz file, as I test with zlib,node-tar and etc. Eventually come out with this hack using ‘tar’ command.

var util  = require('util'),
    spawn = require('child_process').spawn,
    ls    = spawn('tar', ['-C','/home/tony/Desktop','-xvf', '/home/tony/Desktop/tmp.tbz']);

ls.stdout.on('data', function (data) {
  console.log(data);
});

ls.on('exit', function (code) {
  console.log('child process exited with code ' + code);
});

I temporary accept my answer, until better one comes.
