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 🙏

Readable global identifiers

pkg.go.dev NPM Go Report Card pipeline status coverage report

A package providing functions to generate and parse readable global identifiers.

Features:

  • Identifiers have 128 bits of entropy, making them suitable as global identifiers.
  • By default identifiers are random, but you can convert existing UUIDs.
  • They are encoded into readable base 58 strings always of 22 characters in length.

Installation

Go installation

You can add it to your project using go get:

go get gitlab.com/tozd/identifier

It requires Go 1.20 or newer.

TypeScript/JavaScript installation

You can add it to your project using npm:

npm install --save @tozd/identifer

It requires node 20 or newer. It works in browsers, too.

Usage

Go usage

See full package documentation on pkg.go.dev.

TypeScript/JavaScript usage

import { Identifier } from "@tozd/identifier"

const id = Identifier.new() // A random identifier.
const s = id.toString()
console.log(s)
Identifier.valid(s) // True.
Identifier.fromString(s) // Is equal to id.
const u = Identifier.fromUUID("c97e2491-dd58-4a4e-b351-d786554e2ae6") // Is equal to Rt7JRSoDY1woPhLidZNvz1.
JSON.stringify({ id }) // Works, id is converted to string.

Related projects

  • Nano ID – a similar project which allows more customization (both choosing the alphabet and the size); this project supports only one type of identifiers to make sure everyone using it has the same identifiers.

GitHub mirror

There is also a read-only GitHub mirror available, if you need to fork the project there.
