base path URL is not configurable about vite_ruby

Hi Yann!

assetHost is intended for an external CDN host.

Hosting a Rails app in a nested path is unusual, but I think it makes sense to add a separate base setting in config/vite.json to support this use case.

{
  "all": {
     "watchAdditionalPaths": [],
  },
  "production": {
    "base": "my-app"
  }
}

Let me know if you would be willing to rework #152 to add the base setting instead of modifying the assetHost behavior.

const base = `${assetHostWithProtocol || config.base}/${config.publicOutputDir}/`

It would also make sense to allow configuring this setting using environment variables, like for other settings (VITE_RUBY_BASE=my_app). All it takes to implement that, is adding a default value for base:

  "base": "",

Released [email protected] and [email protected] which add support for the base setting.

Run bin/vite upgrade to bump both dependencies.

Thanks! 😃
