Circular dependency in Resource's

The CityResource wouldn't load the Country when you are getting the data like

return CountryResource::collection(Country::query()->with('cities')->get());

[topaz stag]

I assumes your resources are something like

//CountryResource
return [
  'country'=>$this->resource->name,
  'cities'=> CityResource::collection($this->whenLoaded('cities'))
];
// CityResource
return [
 'city'=>$this->resource->name,
  'country'=> new CountryResource($this->whenLoaded('country'))
];

The keys(cities /country) will be shown if you have loaded the relationship, others will remain the same.

Which nested relations would you miss?
What kind of example would you like to archive?

Something like this?

return [
  'city' => [
    'id' => ...., 
    'country' => [
      // data of country
      'citiesIds' => [...] // array including all ids of all related cities
     ],
  ]
];
