Only load select options once per request?

[jaxramus]

I have a Select field that looks like this:

Select::make('Icon')->options($this->iconOptions())->searchable(),

Here is my iconOptions method:

public function iconOptions()
{
    $iconYaml = Yaml::parse(file_get_contents(resource_path('icons/icons.yml')));
    $iconOptions = [];

    foreach ($iconYaml as $key => $value) {
        if (strlen($key) > 1 && in_array('solid', $value['styles'])) {
            $iconOptions["fa-solid fa-$key"] = $value['label'];
        }
        else if (in_array('brands', $value['styles'])) {
            $iconOptions["fa-brands fa-$key"] = $value['label'];
        }
    }

    return $iconOptions;
}

This method parses the Font Awesome icon YAML file to return an array of icon classes.

My problem is that, when viewing things like the resource index, it is hitting the iconOptions method for every row. Since the icons.yml file is quite large, this slows down the request a lot.

How do I get Nova to only load hit the iconOptions method once per request?

Ended up just doing it with caching.

You can also use closure so it only resolve when needed

Select::make('Icon')->options(function () { return  $this->iconOptions(); })->searchable()
