Load firebase and forget

I know that you have only one firebase app in your project and is weird how you initialize it, so this way no amount of messy code can cause multiple loads :

import {initializeApp, cert, getApps} from 'firebase-admin/app';

const existentApps = getApps();

export const firebaseAdminAppInstance =
  existentApps?.[0] ||
  initializeApp({
    credential: cert(JSON.parse(process.env.FIREBASE_ADMIN_APPLICATION_CREDENTIALS || '{}')),
  });

export default firebaseAdminAppInstance;

⚠️ The example is using firebase-admin because in web client should work ok no matter what.
