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 🙏

Based on

This should help (email is messy) to detect if an email message is a bounce message

Usage

check if an email is a bounce

  const EmailSnoop = require('mail-bounce-snoop');

  let message = "<email as text with all header and parts>";

  //using Promise
  EmailSnoop.isBouncedEmail(message).then(isBounce => {
      if (isBounce) {
        console.log("This is a bounce message")
      }
  });
  
  //using callback
  EmailSnoop.isBouncedEmail(message.toString(), (isBounce) => {
      if (isBounce) {
        console.log("This is a bounce message")
      }
  });  
  
  //The message could be set with EmailSnoop.init(message), otherwise the snoop remembers the last used email

get bounce detail

  const EmailSnoop = require('mail-bounce-snoop');
  
  //using Promise
  EmailSnoop.getBouncedEmailDetail(message.toString()).then(result => {
    /*
    * e.g. result 
    * {
    *   "recipient":"[email protected]",
    *   "status":"5.0.0",
    *   "action":"failed",
    *   "messageid":"<[email protected]>",
    *   "is":"bounce"
    * } 
    */
  });
  
  //using callback
  EmailSnoop.getBouncedEmailDetail(message.toString(), (result) => {
     //...
  });  

Example combination

  const EmailSnoop = require('mail-bounce-snoop');
  
  EmailSnoop.init(message);

  //using the email set via init
  EmailSnoop.isBounced((isBounce) => {
      if (!isBounce) {
        console.log("All fine");
        
        return;
      }
      
      //using the email set via init or previous function call
      EmailSnoop.getBouncedDetail().then(result => {
        console.log(`Email to ${result.recipient} failed with status ${result.status}`)
      });
  });
