it says its not a valid package

[infermi]

taos doesn't appear to be written in CJS, but also doesn't appear to be a valid ES module (i.e. it doesn't have "type": "module" or an .mjs extension for the entry point). Please contact the package author to fix.

thats what is says

At the moment TAOS is meant to be used for static sites, the npm package is for Tailwind plugin.

You can either use the CDN link or download the JS from there. It is a tiny package so you can even inline the JS so that the page speed is faster.
