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 🙏

Prism Live

Editable code areas powered by Prism.
WIP, use at your own risk and do not assume that the API will not change.

  • Npm: [@victr/prism-live](https://www.npmjs.com/package/@victr/prism-live)
  • Demo: [prism-live.pages.dev](https://prism-live.pages.dev)
  • Original demo: [live.prismjs.com](https://live.prismjs.com)

Install

npm install @victr/prism-live

Use a Prism theme stylesheet first

<head>
    <link rel="stylesheet" href="/prism.css" />
</head>

Import prism & prism-live in a javascript file

import javascript from "@victr/prism-live/language/javascript";
import PrismLive from "@victr/prism-live";
import Prism from "@victr/prism-live/prism";
import "@victr/prism-live/style.css";

// Some setup is needed, this adds Prism to Live
const prism = new Prism();
prism.addLanguage(languageJavascript);
PrismLive.addPrism(prism);

// Use Prism Live
PrismLive.createAll();

Or in a script tag

<head>
    <script type="module">
        import javascript from "@victr/prism-live/language/javascript";
        import PrismLive from "@victr/prism-live";
        import Prism from "@victr/prism-live/prism";
        import "@victr/prism-live/style.css" assert { type: "css" };

        // Some setup is needed, this adds Prism to Live
        const prism = new Prism();
        prism.addLanguage(languageJavascript);
        PrismLive.addPrism(prism);

        // Use Prism Live
        PrismLive.createAll();
    </script>
</head>

Then create a code editor like this

<textarea class="prism-live language-css" />

Why

I needed a lightweight code-editor and chose prism-code-editor. However I wanted to see what Prism live had to offer! This is a working package based on the current development.

This will die once Prism Live & Prism version 2 are available 😲

What changed

  • Import Prism v2 from package instead of using global Prism v1
  • Added addLanguage to Prism v2 and addPrism to Prism Live for tree-shaking
  • To work, Live needs a reference to Prism with addPrism

Broken

  • Did not check if line numbers styling is working, oops

Development

  • Use Prettier with config close to original formatting style
  • Use dev files of blissfuljs & Prism version 2
  • Main Prism v2 file built with esbuild ./src/core.ts --bundle --format=esm --outfile=prism.js

Demo

  • Demo website as a static site generated by Vite
  • Self hosted images and stylesheets
  • No blissful in demo
  • Constant strings as html/css/javascript example
