如何配置express-handlebars将其与nodemailer链接？

Question

嗯，我有一个通过Nodemailer发送电子邮件的API。我希望将电子邮件呈现为HTML，因此我尝试将nodemailer-express-handlebar连接到我的api：

const nodemailer = require('nodemailer')
const hbs = require('nodemailer-express-handlebars)

const sendMail = async (options) => {
    try {
        const transporter = nodemailer.createTransport({
            host: process.env.EMAIL_HOST,
            port: process.env.EMAIL_PORT,
            auth: {
                user: process.env.EMAIL_USER,
                pass: process.env.EMAIL_PASS,
            },
        })

        transporter.use(
            'compile',
            hbs({
                viewEngine: {
                    extName: '.hbs',
                    partialsDir: './views/', 
                    layoutsDir: './views/layouts',
                    defaultLayout: '',
                },
                extName: '.hbs',
                viewPath: 'views',
            })
        )
        const mailOptions = {
            from: 'abc@abc.com',
            // to: 'cde@cde.com',
            to: options.email,
            bcc: 'me@me.com',
            subject: 'Booking confirmation',
            template: 'emailHtml',
        }

        await transporter.sendMail(mailOptions)
    } catch (err) {
        return new AppError(
            'There was an error while sending the email. Please, try again later.',
            500
        )
    }
}

下面是我的应用程序接口的文件结构(应用程序接口本身在email.js中，util文件夹在根目录中)：

​

​

在main.hbs中，主体中只有{ html5 }的标准主体标记，而在emailHtml.hbs中，h1标记中只有hello world。

然而，它不起作用(我认为问题可能是在错误的道路上，但我尝试了许多组合)。我知道有一种方法可以使用样式和变量来指定html：<h1> hello world </h1>，但这对我来说不是一个合适的解决方案，所以模块化的解决方案对我会很有帮助。当我删除hbs配置并将纯文本放入mailOptions中时，电子邮件已发送，但一旦我放入模板，它就停止工作。Dotenv已经配置好了，我只是没有把它放在这里。

有什么想法吗？

如果email.js和layouts文件夹在同一个文件夹中，那么下面的代码将会工作。

const nodemailer = require('nodemailer') 
const hbs =require('nodemailer-express-handlebars)

const sendMail = async (options) => {
    try {
        const transporter = nodemailer.createTransport({
            host: process.env.EMAIL_HOST,
            port: process.env.EMAIL_PORT,
            auth: {
                user: process.env.EMAIL_USER,
                pass: process.env.EMAIL_PASS,
            },
        })

        transporter.use(
            'compile',
            hbs({
                viewEngine: {
                    extName: '.hbs',
                    partialsDir: 'layouts/', 
                    layoutsDir: 'layouts/',
                    defaultLayout: 'emailHtml',
                },
                extName: '.hbs',
                viewPath: 'layouts/',
            })
        )
        const mailOptions = {
            from: 'abc@abc.com',
            // to: 'cde@cde.com',
            to: options.email,
            bcc: 'me@me.com',
            subject: 'Booking confirmation',
            template: 'emailHtml',
        }

        await transporter.sendMail(mailOptions)
    } catch (err) {
        return new AppError(
            'There was an error while sending the email. Please, try again later.',
            500
        )
    } }
