decompress tgz in nodejs

decompress-tgz.js

var fs = require('fs');
var zlib = require('zlib');
var path = require('path');
var tar = require('tar');
var mkdirp = require('mkdirp');

// 全解压
fs.createReadStream(path.resolve('./ice-2.0.50.tgz'))
  .on('error', console.log)
  .pipe(zlib.Unzip())
  .pipe(tar.Extract({
    path: './aaaa',
    strip: 1
  }))

// 选择文件
fs.createReadStream(path.resolve('./ice-2.0.50.tgz'))
  .on('error', console.log)
  .pipe(zlib.Unzip())
  .pipe(tar.Parse())
  .on('entry', function(entry) {
    if (/\.scss$/.test(entry.path)) {
      var filepath = path.join(__dirname, entry.path);

      mkdirp.sync(path.dirname(filepath))
      entry.pipe(fs.createWriteStream(filepath));
    }
  })

TypeError: tar.Extract is not a function

The latest tar implementation from npm replaces Extract with x and path with C.

fs.createReadStream(path.resolve('./ice-2.0.50.tgz'))
  .on('error', console.log)
  .pipe(zlib.Unzip())
  .pipe(tar.x({
    C: './aaaa',
    strip: 1
  }))

I know this is an old gist, but this came up in my search so I figured I'd post an updated approach. The following are not replacing part of the original gist, they are the full gists.

Unzip synchronously

tar.x({ C: `./aaaa`, file: `./ice-2.0.50.tgz`, sync: true });

Unzip with callback

tar.x({ C: `./aaaa`, file: `./ice-2.0.50.tgz` }, undefined, (err) => {  
   // Error handling code here
});

Unzip asynchronously

await tar.x({ C: `./aaaa`, file: `./ice-2.0.50.tgz` })
