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 🙏

Shahnevis Core is a lightweight and flexible library for building custom code editors.

This library is framework-agnostic, meaning you can use it in React, Vue, or any other JavaScript environment.

✅ Plugin system for extensions
✅ Language support for syntax parsing


📦 Installation

You can install shahnevis-core via npm:

npm install shahnevis-core

or using yarn:

yarn add shahnevis-core

🛠️ Usage

Example: Using Shahnevis Core in React

import { 
  languages, highlightHandler, updateSyntaxHighlighting, minimapHandler, updateMinimapContent,
  featureHandler, updateIndentationGuides, handleSuggestions, pluginManager, loadExternalPlugins,
  globalState, cleanForFolded, detectChange, generateFullCode, updateFoldingState

🔌 Plugin System

Shahnevis Core supports a plugin system that allows developers to extend functionality dynamically.

📥 Creating a Plugin

Here's an example of a Preview Plugin that updates an iframe when the user writes HTML code:

export default {
  init() {
    console.log("Preview Plugin Loaded!");
  },

  onLanguageChange(language) {
    if (language === "html") {
      console.log("HTML selected!");
    }
  },

  onInput() {
    const languageSelector = document.getElementById("language-selector");
    const previewFrame = document.getElementById("preview-frame");
    const editor = document.getElementById("editor");

    if (!languageSelector || !previewFrame || !editor) {
      console.warn("Preview Plugin: Missing required DOM elements.");
      return;
    }

    const language = languageSelector.value;
    if (language === "html") {
      previewFrame.srcdoc = editor.value;
    }
  }
};

🛠️ Registering the Plugin

To register this plugin, use:

const pluginURLs = [
    'path to plugin'
]

const loadPlugins = async () => {
    await loadExternalPlugins(pluginURLs);
    console.log("Plugins loaded.");
};
loadPlugins();

🌍 Supported Languages

Shahnevis Core comes with built-in support for multiple programming languages via the languages module. You can extend this list with additional parsers.
