Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

mail-queuer

mail-queuer是提供一个邮件队列服务,它可以部署到一台专门的服务器上。经过验证的服务器可以向它发送邮件任务,它会将发送任务排队,然后依次执行任务。一个很典型的应用类似于这样,我们把mail-queuer部署到appFog(例如:smtp.af.cm)上,而将你的网站部署在自己的服务器上,当你需要向用户发送一个欢迎邮件时,您只需要向smtp.af.cm这个服务器发送一个邮件任务即可。 mail-queuer还有一个特点就是可以根据模板(jade)渲染邮件,并且可以支持国际化邮件,你可以设置各种语言的模板。请求服务器只需要提供JSON数据即可,并且邮件的标题也是可以格式化的。

应用场景

mail-queuer适合批量发送邮件,例如会员的欢迎邮件、激活邮件、订单邮件等等。与SES这类服务不同的是,mail-queuer可以渲染邮件。所以,你可以将mail-queuer部署到一个若干个免费云上,让它们免费为你工作,减少对生产服务器的压力。

Install

$ npm install mail-queuer

如何使用

邮件队列服务器

1.引入定义及配置mongoose

  var nodemailer = require("nodemailer");
  var mongoose = require("mongoose");
  var mailQueuer = require('mail-queuer');
  mongoose.connect('mongodb://localhost/mail-queuer');

2.创建一个发送邮件的函数

通常一个发送邮件的函数如下所示,在options参数中,提供options.subject(邮件主题)、options.html(邮件内容)、options.to(收件)、

function sendMail(options, callback){
  //发送邮件
  callback();
};

如果你的项目中有使用nodemailer,你也可以这样:

function sendMail(options, callback){
  var transport = nodemailer.createTransport("SMTP", {
    service: "Gmail",
    auth: {
      user: "[email protected]",
      pass: "password"
    }
  });

  transport.sendMail({
    from: "[email protected]",   //发件人,一般要和user一致
    to: options.receiver,           // 收件人
    subject: options.subject, //邮件主题
    html: options.html        //邮件内容
  }, function(err, res){
    transport.close();
    callback(err);
  });
};

3.在configure中,初始化中间件

var options = {
  //模板路径
  templatePath: __dirname + "/template/",
  //模板对应的配置
  templateSubject: {
    "welcome": {
      "en": "Welcome %name%",
      "zh_CN": "欢迎%name%"
    }
  },
  //每发一份邮件,休息多长的时间再发送
  sleep: 5,
  //限制指定IP才能发起邮件请求
  ip: null,
  //握手的token,用于校验发起请求方
  token: "conis",

};
app.use(mailQueuer.initialize(mongoose, options, sendMail));

4.添加新建邮件任务的路由

app.get("/addTask", function(req, res, next){
  mailQueuer.newTask(req, res, next);
});

参数说明

  1. templatePath:模板的绝对路径
  2. sleep:每发一份邮件中断多久,有些邮件服务器可能会禁止频繁发邮件的,如果邮件服务器是自己的就不用考虑了
  3. ip:限制请求服务器的ip数组,允许是正则表达式
  4. token:校验请求服务器的token
  5. templateSubject:邮件主题的模板

请求服务器

请求服务器只需要发送一个post请求过去就可以,需要提供的数据为tokensubject(邮件主题的JSON数据)、data(邮件内容的JSON数据)、template(使用哪个模板)、language(语言,默认为en)。

Examples

请见 ./examples/app.js
