Work with a task that needs to generate exceles based on certain data and send them to the specified e-mail.

Generating Excel

Library "exceljs" used.

It's very powerful, and l only use a small part of the functionality.

The code is as follows.

'use strict'
const Excel = require('exceljs');
var workbook = new Excel.Workbook();
// 创建页面
var ws1 = workbook.addWorksheet('名字');
ws1.addRow(["订单号", "商品"]);

// 标题颜色
['A1', 'B1', 'C1'].forEach((name, index) => {
    ws1.getCell(name).fill = {
        type: "pattern",
        pattern: "solid",
        fgColor: { argb: "4682B4FF" }
    };

    ws1.getCell(name).font = {
        color: { argb: 'FFFFFFFF' },
        bold: true
    };

});

// 每一个标题的宽度
ws1.getColumn(1).width = 20;
ws1.getColumn(2).width = 15;

ws1.addRow(['11111', '22222']);
workbook.xlsx.writeFile('文件名字')
   .then(()=>{
   });

Send Email

Library "nodemailer" used.

We just call the interface through the mail server sending Email.
Building Email Server

The code is as follows.

const nodemailer = require('nodemailer');
const sendController = nodemailer.createTransport({
    service: 'qq', // 使用了内置传输发送邮件 查看支持列表：https://nodemailer.com/smtp/well-known/
    port: 465, // SMTP 端口
    secureConnection: true, // 使用了 SSL
    auth: {
        user: '账号',
        pass: '不是 qq 密码，设置的 smtp 授权码'
    }
});

   const mailOptions = {
        from: `"系统自动发送" <'发送邮箱地址'>`,
        to: '收件人的邮箱，“,” 隔开可以发送多人 ',
        subject: `子标题`,
        html: `<b>内容</b>`
        // 附件路径
        attachments: [{
            filename:  '文件名字',
            path: '发送的文件路径'
        }]
    };

 sendController.sendMail(mailOptions, (error, info) => {
          
 });
