diagrams-js: TypeScript/JavaScript port of diagrams

[hatemhosny]

Hi @mingrammer and the diagrams community,

I wanted to share a project I've been working on/vibe-coded:
diagrams-js, a TypeScript/JavaScript port of the excellent Python diagrams library.

Why a TypeScript Port?
The JavaScript/TypeScript port offers some unique advantages:

• Browser support - runs directly in browsers with no build step required (try the playground)
• Cross-platform - works in Node.js, Deno, and Bun
• Dependency-free - uses a WebAssembly build of Graphviz, no external dependencies
• Type safety - full TypeScript support with IDE autocompletion for the 2000+ nodes
• Data URL rendering - returns base64 data URLs for easy embedding in HTML

The API is intentionally very similar to the Python version, adapted to TypeScript idioms:

• Python's with Diagram(): → TypeScript's const diagram = Diagram()

• Python's >> operator → TypeScript's .to() method

• Python's << operator → TypeScript's .from() method

• Same provider paths and class names for all 2000+ nodes
  I've created a comprehensive migration guide that shows side-by-side comparisons of Python vs TypeScript syntax, including a dedicated AI skill that can automatically convert Python diagrams code to TypeScript.

• 📚 Full Documentation

• 🎮 Interactive Playground

• 📝 Migration Guide

• 🤖 AI Guide & Skills

• 💻 GitHub Repository

This project would not exist without the original diagrams library. I've created a credits page acknowledging the original work, added acknowledgments section in the repo's README, and the project maintains the same MIT license.

Thank you for creating such an elegant and powerful tool for drawing cloud architecture diagrams as code. The diagrams library has been incredibly valuable to the community.

I was wondering if you would welcome a PR to add diagrams-js to the README under the "Other languages" section? I believe it could help JavaScript/TypeScript developers discover the library and provide another option for those who prefer working in that ecosystem.
Thank you for this fantastic project!
