使用officegen創建和下載Word文檔的Node.js

Question

我想使用officegen npm模塊創建一個單詞（docx）文件並下載它。在過去，我使用tempfile模塊來創建下載目的的臨時路徑。這裏是代碼我寫的word文檔下載：

var tempfile = require('tempfile'); 
var officegen = require('officegen'); 
var docx = officegen('docx'); 

router.post('/docx', function(req, res){ 
    var tempFilePath = tempfile('.docx'); 
    docx.setDocSubject ('testDoc Subject'); 
    docx.setDocKeywords ('keywords'); 
    docx.setDescription ('test description'); 

    var pObj = docx.createP({align: 'center'}); 
    pObj.addText('Policy Data', {bold: true, underline: true}); 

    docx.on('finalize', function(written) { 
     console.log('Finish to create Word file.\nTotal bytes created: ' + written + '\n'); 
    }); 
    docx.on('error', function(err) { 
     console.log(err); 
    }); 

    docx.generate(tempFilePath).then(function() { 
     res.sendFile(tempFilePath, function(err){ 
      if(err) { 
       console.log('---------- error downloading file: ' + err); 
      } 
     }); 
    }); 
}); 

但是它給了我一個錯誤說

TypeError: dest.on is not a function

創建也顯示爲0。我在做什麼錯的總字節？

router.post('/docx', function(req, res){ 
    var tempFilePath = tempfile('.docx'); 
    docx.setDocSubject ('testDoc Subject'); 
    docx.setDocKeywords ('keywords'); 
    docx.setDescription ('test description'); 

    var pObj = docx.createP({align: 'center'}); 
    pObj.addText('Policy Data', {bold: true, underline: true}); 

    docx.on('finalize', function(written) { 
     console.log('Finish to create Word file.\nTotal bytes created: ' + written + '\n'); 
    }); 
    docx.on('error', function(err) { 
     console.log(err); 
    }); 

    res.writeHead (200, { 
    "Content-Type": "application/vnd.openxmlformats-officedocument.documentml.document", 
    'Content-disposition': 'attachment; filename=testdoc.docx' 
    }); 
    docx.generate(res); 
});
