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.

MCP Chart Server v2 (Node v20.19.2 Fix)

This is a fixed version of the MCP Chart Server to work with Node.js v20.19.2. The original version had issues with ESM module loading in newer Node.js versions, causing an internal assertion error.

Fixed Issues

The following issues were fixed:

Updated dynamic imports to use file:// URL protocol with absolute paths
Added .js extensions to all imports for proper ESM resolution
Added file path utilities (fileURLToPath, dirname, resolve) for proper module resolution
Removed dynamic import in main index.ts file to avoid ESM loading issues

How to Use

Prerequisites

Node.js v20.19.2 (as specified in package.json)

Installation

npm install

Build

npm run build

Run

npm run start

Testing the Server

You can test the server using:

npm run simple-server

Or with the example:

npm run example

If You Still Encounter Issues

If you still encounter ESM module loading issues, you can run the fix script:

chmod +x fix-esm-imports.sh
./fix-esm-imports.sh
npm run build

Using with LibreChat

This fixed version should now work correctly when integrated with LibreChat using Node.js v20.19.2.
