📚 Description

https://docs.cookie3.co/cookie3-docs/integrations/website-integration/cookie3-script/nuxt

uses custom matomoto white-label analytics but some enhancement:

• uses global variables (ps. 🤷‍♂️)
• custom url in script src
• another trackerUrl
• not use siteId

but have a questions (ps. hi @harlan-zw):

1. It would probably be cool to use an or construction
   matomoUrl or trackerUrl but probably optional easier to implement.

2. I didn't modify scriptInput.src in the hope that if it is specified to the user explicitly it will overwrite the existing one, is this true ?

@reslear is attempting to deploy a commit to the Nuxt Team on Vercel.

A member of the Team first needs to authorize it.

hm maybe we can deprecate this in favour if trackerUrl

[reslear]

probably, because in the official documentation this name is used as an environment variable - apparently as syntax sugar

var u="//{$MATOMO_URL}/";
    _paq.push(['setTrackerUrl', u+'matomo.php']);

I just don't know your policy on major releases so I left it for backwards compatibility. If it's not important, I'd remove it in favor of proper names and add full url's to doc.

Would you mind taking a look at the typecheck issue? then it should be good to go
