How can it be defined dependency free if it depends on Node.js?

Dependency-free means zero runtime dependencies, not no dev tools. Could have explained that better.

Do you mean I don't need Node.js on the machine where I run it?

It's a web component so you run it in the browser without dependencies after it's already been built with Node.

Doesn’t need to be built by node. It’s standalone.

it needs an operating system to run omg not dependency free

LOL, and an internet connection, too!

But, seriously, of course "web" requires internet and a computer and an operating system. But since when "web" also means Node.js?

If a web component is advertized as dependency free, I expect something that I can include in a <script> tag and it works. Am I wrong?

i mean fwiw can prolly include direct script tag using something like https://esm.sh

Does this operating system also depend on an underlying computer?

You're free to just step through the assembly manually. You might need some paper and a pen.

It ain't dependency free, if you need pen and paper.
