Move Docus Colors to settings.json

[atinux]

I would love to be able to move the colors to the settings.json to docus won't add any key inside the Nuxt config directly.

We could leverage the CSS variables in order to give TailwindCSS custom colors on runtime: https://levelup.gitconnected.com/tailwindcss-with-css-variables-513abe2e9a5

This way, we could have HMR on the docus theme colors.

Would you want to try to implement it @farnabaz ?

Manifest theme_color seems an issue in migrating to CSS variable https://github.com/nuxtlabs/docus/blob/main/theme/nuxt.config.js#L51

Well I guess we could anyway compute them for the nuxt.config.js since they are used for loading.color too, but mostly useful when running nuxt build.

loading.color works fine with css variables because it renders on the page.

What is the right way to detect path of settings.json before Nuxt initialization?

I think we shall do it right inside module.js since we can have user srcDir + content/settings.json directly.

Then we can overwrite directly the user config there.
