app.get("/inventoryItems", async (req, res) => {

  const page= parseInt(req.query.page);
  const size =  parseInt(req.query.size);
  **const email = req.query.email**
  const query = {}; 
  const cursor = inventoryItemsCollection.find(query);    
  let inventoryItems ;
  if( page || size ){

    inventoryItems = await cursor.skip(page*size).limit(size).toArray();
    
    
  }else{

    inventoryItems = await cursor.toArray();
  }
