send-email.js

import parser from 'lambda-multipart-parser'
import nodemailer from 'nodemailer'

const handler = async (event, context, callback) => {
  const transporter = nodemailer.createTransport({
    host: 'smtp.ethereal.email',
    port: 587,
    auth: {
      user: process.env.ETHEREAL_USER,
      pass: process.env.ETHEREAL_PASS,
    },
  })

  const result = await parser.parse(event)
  const { name, email, phone, position, files } = result

  const subject = `[${position}] ${name}`
  const text = `
    Name: ${name}\n
    Applying for position: ${position}\n
    Phone: ${phone}\n
    Email: ${email}\n
    CV: find attachment\n
    Cover Letter: find attachment
  `

  transporter.sendMail(
    {
      from: 'test-sender@example.com',
      to: 'hrd@company.com',
      replyTo: email,
      subject,
      text,
      attachments: files,

    (error, info) => {
      if (error) {
        callback(error)
      } else {

          statusCode: 200,
          body: 'Ok',
        })
