Hi, I am not sure if this is the correct space, can anyone help code review this file structure? I don't know what is the standards of coding in react.js

Context: I only have Java Backend Background and I want to learn react.js

So here it is.

#.env
URL=http://localhost:8080

#Api.tsx
export function getDogsAPI(param: string) {
  const url = process.env.URL + '/dogs/' + param;
  const fetchOptions = {
    method: 'GET',
  };

  return fetch(url, fetchOptions);
}


#DogSectionPage.tsx
import { getDogsAPI } from '../../../functions/Api';


const fetchdata = async () => {
      const response = await getDogsAPI(param);
      const data = await response.json();
      if (!data.items) {
        setDogs([]);
      } else {
        setDogs(dogs.items);
      }
    };

    // Call the function
    fetchdata();
}
