Show HN: TypeScriptNotebook – Experiment with NPM in the Browser

A free, in-browser Jupyter-style notebook for TypeScript. It supports npm installs, network requests, and more—no signup or setup required.

Why I Built It I wanted a simple way to test npm packages, experiment with TypeScript, and work on ideas like prompt engineering without heavy setup or local tools.

Features - npm Integration: Install and use packages instantly. - Network Requests: Test APIs right in the notebook. - TypeScript Playground: Experiment, debug, and share code.

It’s ideal for developers, educators, and anyone wanting a TypeScript scratch pad. Give it a try at TypeScriptNotebook.com.

I’d love your feedback—what works, what doesn’t, and what you’d like to see next! https://typescriptnotebook.com
