Compresser le contenu d'un dossier dans un fichier zip en utilisant ZLIB et le nœud

Question

Je dois compresser le contenu d'un répertoire dans un seul fichier ZIP.

J'utilise le code suivant:

var fs = require('fs'); 
var tar = require('tar'); 
var zlib = require('zlib'); 
var path = require('path'); 
var mkdirp = require('mkdirp'); 
var fstream = require('fstream'); 
fstream.Reader({path:"E:\\ddata\\electron\\Applications\\FirstApp\\js\\temp\\",type:"Directory"}) 
.pipe(new tar.Pack()) 
.pipe(zlib.Gzip()) 
.pipe(fstream.Writer({path:"C:\\Users\\Raina\\AppData\\Local\\Temp",file:'compressed_folder.tar.gz' })); 

Mais je reçois cette erreur:

path.js:7 throw new TypeError('Path must be a string. Received ' + inspect(path));

Comment puis-je me débarrasser de cette erreur et si je dois déboguer où est le path.js ?

Trouvez ci-dessous le code complet pour ZIP et décompressez

var fs = require('fs'); 
var tar = require('tar'); 
var zlib = require('zlib'); 
var path = require('path'); 
var mkdirp = require('mkdirp'); 
var archiver = require('archiver'); 
var log = console.log;

uid=Date.now().toString().substr(Date.now().toString().length - 4); 



const tempDir = require('temp-dir'); 
var destdir = tempDir + '\\lay'+uid+'.tmp'; 
mkdirp(destdir, function(err) 
{ 
    if (err) throw err; 
    }); 

function unzip() 
{ 

    var srcdir = 'E:/d data/electron/Applications/FirstApp/js/red.le2'; 
    //var destdir = 'E:/d data/electron/Applications/FirstApp/js/temp'; 

    fs.createReadStream(srcdir) 
     .on('error', log) 
     .pipe(zlib.Unzip()) 
     .pipe(new tar.Parse()) 
     .on('entry', function(entry) { 
     // if (/\.js$/.test(entry.path))// only extract JS files, for instance 
     { 
      var isDir  = 'Directory' === entry.type; 
      var fullpath = path.join(destdir, entry.path); 
      var directory = isDir ? fullpath : path.dirname(fullpath); 
      console.log (fullpath) 
       mkdirp(directory, function(err) { 
      if (err) throw err; 
      if (! isDir) { 
       entry.pipe(fs.createWriteStream(fullpath)); 
       ; 
      } 
      }); 
     } 
     }); 
} 


function zip() 
{ 
    destdir='C:/Users/Raina/AppData/Local/Temp/lay0054.tmp'; 
    var output = fs.createWriteStream('C:/Users/Raina/AppData/Local/Temp/xx.le2'); 
    var archive = archiver('tar', { 
     zlib: { level: 9 } 
    }); 
    output.on('close', function() { 
     console.log(archive.pointer() + ' total bytes'); 
     console.log('archiver has been finalized and the output file descriptor has closed.'); 
    }); 
    archive.on('warning', function(err) { 
    if (err.code === 'ENOENT') { 
     // log warning 
    } else { 
     // throw error 
     throw err; 
    } 
    }); 
    archive.on('error', function(err) { 
    throw err; 
    }); 
    archive.pipe(output); 
    archive.directory(destdir+'/layout', 'layout'); 
    archive.file(destdir+'/layout_new.xml', { name: 'layout_new.xml' }); 
    archive.finalize();
