Question

var express = require('express'); 
 
var exphbs = require('express-handlebars'); 
 
var MailerConnect = require('./nodemailer.js'); 
 

 
var app = express(); 
 

 
app.engine('handlebars', exphbs({ 
 
    defaultLayout: 'test' 
 
})); 
 
app.set('view engine', 'handlebars'); 
 

 
var file = module.exports = { 
 
    Mailer: function(req, res) { 
 
    res.render('testtemplate', function(err, data) { 
 
     var data = data; 
 
     console.log(data); 
 
     MailerConnect.sendMail(data); 
 
    }); 
 
    } 
 
}

無法評論，但如此認爲這是一個註釋。

您的公用文件夾集？

app.set('views', path.join(__dirname, 'views'));
