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 🙏

Check if an email domain belongs to an educational institution.

CircleCI Coverage Status version

Why?

We offer AnonymityBot for free for educational workspaces but couldn't find an efficient way to detect email domains of educational institutions.

Why Open Source?

Why not?

We’ve been students and lecturers ourselves and personally felt the communicational hardships affecting both sides (the fear of being ridiculed for asking a question, the moment no one asks questions - not knowing if they got it, etc.) and therefore think that more software should offer Pro Bono tiers for educational purposes.

For this reason, we decided to open source our software that automatically detects if an email domain belongs to an educational institution.

You can read more here.

API

hasCommonEducationalTld(domain)

We call a TLD Common Educational TLD if it is either .edu, .edu.xx or .ac.xx and was fetched from publicsuffix.org.

hasAdhocEducationalTld(domain)

Some institutions don't use edu or ac TLDs, and (usually) use their own country code. For instance, University of Oslo has an email domain for each department - math.uio.no, fys.uio.no - in order to capture all such departments we simply check for uio.no.

isEducationalEmailDomain(domain)

Combines hasCommonEducationalTld and hasAdhocEducationalTld:

const isEducationalEmailDomain = (domain) =>
  hasCommonEducationalTld(domain) || hasAdhocEducationalTld(domain);

Where is the data coming from?

See ./assets.

Example

Install with yarn add @anonymitybot/is-educational-email-domain:

const {
  isEducationalEmailDomain,
  hasAdhocEducationalTld,
  hasCommonEducationalTld,
} = require('@anonymitybot/is-educational-email-domain');

(async () => {
  hasCommonEducationalTld('stanford.edu'); // true
  hasCommonEducationalTld('u-tokyo.ac.jp'); // true
  hasCommonEducationalTld('cuhk.edu.cn'); // true

  hasCommonEducationalTld('bla.cc'); // false - .ac is a ccTLD

  hasAdhocEducationalTld('math.ethz.cz'); // true - etch.cz is an ad-hoc educational domain
  hasAdhocEducationalTld('stanford.edu'); // false - .edu is a common educational tld (but not an ad-hoc one)

  isEducationalEmailDomain('stanford.edu'); // true
  isEducationalEmailDomain('math.ethz.cz'); // true

  isEducationalEmailDomain('bla.cc'); // false - .ac is a ccTLD
})()
