### Create Pydantic *models* / schemas for reading / returning

Now create Pydantic *models* (schemas) that will be used when reading data, when returning it from the API.

For example, before creating an item, we don't know what will be the ID assigned to it, but when reading it (when returning it from the API) we will already know its ID.

### Creating the `Settings` only once with `lru_cache`

Reading a file from disk is normally a costly (slow) operation, so you probably want to do it only once and then re-use the same settings object, instead of reading it for each request.

But every time we do:

```Python
Settings()
```

	flag.IntVar(&port, "port", 8080, "Port to listen on")
}

func mainHandler(w http.ResponseWriter, r *http.Request) {
	body, err := io.ReadAll(r.Body)
	defer r.Body.Close()
	if err != nil {
		log.Printf("Error reading request body: %v", err)
		w.WriteHeader(http.StatusBadRequest)
		return
	}

	log.Printf(">>> %s %s\n", r.Method, r.URL.Path)
	var out bytes.Buffer
	json.Indent(&out, body, "", "    ")

			dcinfo.FreeInodes = di.Ffree
			dcinfo.FSType = di.FSType
			diskID, err := s.GetDiskID()
			// Healing is 'true' when
			// - if we found an unformatted disk (no 'format.json')
			// - if we found healing tracker 'healing.bin'
			dcinfo.Healing = errors.Is(err, errUnformattedDisk) || (s.Healing() != nil)
			dcinfo.ID = diskID
			return dcinfo, err
		},
	)

	// Success.
	return s, nil
}

	}
	r, err := NewReader(bytes.NewReader(data), int64(len(data)))
	if err != ErrInsecurePath {
		t.Fatalf("Error reading the archive: %v", err)
	}
	_, err = r.Open("test.txt")
	if err != nil {
		t.Errorf("Error reading file: %v", err)
	}
	if len(r.File) != 1 {
		t.Fatalf("No entries in the file list")
	}
	if r.File[0].Name != "../test.txt" {

		}
		if stream.Name == "inspect.zip" {
			if extracted {
				return keepFileErr{errors.New("multiple inspect.zip streams found")}
			}
			_, err := io.Copy(w, stream)
			if err != nil {
				return fmt.Errorf("reading inspect stream: %w", err)
			}
			fmt.Println(okMsg)
			extracted = true
			continue
		}
		if err := stream.Skip(); err != nil {
			return fmt.Errorf("stream skip: %w", err)
		}
	}
