Getting rid of NPM

[ryan-senn]

With Phoenix removing NPM entirely, it feels really bad needing it again for Salad UI. From what I can see, it is only used for tailwind-animate, which is essentially one file: https://github.com/jamiebuilds/tailwindcss-animate/blob/main/index.js

Here is what it says on my machine:

Installing tailwindcss-animate
added 113 packages in 7s

Seems a bit crazy to me. I suggest adopting what phoenix did, and simply add a vendor folder with the files needed. See assets/vendor/topbar.js in a new phoenix install.

This way folks don't need node, npm and installing 113 packages just for one file...
