如何将快递邮件配置移动到分隔文件？

Question

在这个npm包的doc中： https://www.npmjs.com/package/express-mailer

Config必须位于app.js文件中：

// project/app.js 

var app = require('express')(),
    mailer = require('express-mailer');

mailer.extend(app, {
  from: 'no-reply@example.com',
  host: 'smtp.gmail.com', // hostname 
  secureConnection: true, // use SSL 
  port: 465, // port for secure SMTP 
  transportMethod: 'SMTP', // default is SMTP. Accepts anything that nodemailer accepts 
  auth: {
    user: 'gmail.user@gmail.com',
    pass: 'userpass'
  }
});

但我有这个结构：

app_dir
   config_dir
       mail.js
   app.js

需要将此块放在mail.js

中

可以这样做吗？

使用js config（你想要的）

// project/config_dir/mail.js

module.exports = {
  from: 'no-reply@example.com',
  host: 'smtp.gmail.com', // hostname 
  secureConnection: true, // use SSL 
  port: 465, // port for secure SMTP 
  transportMethod: 'SMTP', // default is SMTP. Accepts anything that nodemailer accepts 
  auth: {
    user: 'gmail.user@gmail.com',
    pass: 'userpass'
  }
} 

// project/app.js 

var app = require('express')(),
    mail_config = require('./config_dir/mail');
    mailer = require('express-mailer');

mailer.extend(app, mail_config);

使用json config

// project/config_dir/mail.json

{
  from: "no-reply@example.com",
  host: "smtp.gmail.com",
  secureConnection: true,
  port: 465,
  transportMethod: "SMTP",
  auth: {
    user: "gmail.user@gmail.com",
    pass: "userpass"
  }
} 

// project/app.js 

var app = require('express')(),
    mail_config = require('./config_dir/mail.json');
    mailer = require('express-mailer');

mailer.extend(app, mail_config);
