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 🙏

unicode-emojis-unique-id-json

JSON-version of https://unicode.org/Public/emoji/15.0/emoji-test.txt with unique IDs (numbers). The IDs should be unique over time, when new versions of unicode emojis are released. There are a little less than 4000 emojis now if you count the ones with modifiers. I'm guessing it will pass 10000 in the foreseeable future, so the IDs should be 5-digits.

The IDs will start at 00000 and then counting. The reasons for this way of creating IDs instead of some hashing algorithm are two:

  • The IDs need to be numbers
  • The IDs need to be as short as possible

The usage is for the One-time-pad encryption/decryption library. More specific: To be able to encrypt and decrypt emojis (in addition to characters and numbers). Emoji encryption and decryption are done through a codebook, starting with a 0 to be identified as a emoji plaincode and then followed by 5 digits.

Content of JSON

Text-line from https://unicode.org/Public/emoji/15.1/emoji-test.txt

1F600                                                  ; fully-qualified     # 😀 E1.0 grinning face

will be:

[
 {
    "id": "00001",
    "emoji": "😃",
    "description": "grinning face with big eyes",
    "unicode": [
      "U+1F603"
    ],
    "versionIntroduced": "0.6"
  }
]

To get back to the same IDs if something goes wrong

Start from Unicode Emojis v13.0, then run the script on all versions after. That will so far be:

  • 13.0
  • 13.1
  • 14.0
  • 15.0
  • 15.1

Version 15 won't happen before I get regex to work for the two-character emojis introduced in v15.0 and v15.1.

Work to be done

  • [x] regex for extracting content from text-file.
  • [x] read old JSON, fetch new emojis, convert to JSON and add what's not in the old JSON with unique IDs
  • [x] write to JSON
  • [ ] show which unicode emoji versions are met with this library
  • [ ] tests to check that all IDs for previous versions of this library are corresponding to new version of library. Do this by having a previous version directory

Tests

Should have tests to ensure that IDs for previous versions of unicode emoji IDs are persistent.
