compilation to JavaScript, it cannot rely on the types to define validation, serialization and documentation at the same time. Due to this and some design decisions, to get validation, serialization and automatic schema generation, it's needed to add decorators in many places. So, it becomes quite verbose.

It can't handle nested models very well. So, if the JSON body in the request is a JSON object that has inner fields that in turn are nested JSON objects, it cannot be properly documented and...

The important thing is that by using standard Python types, in a single place (instead of adding more classes, decorators, etc), **FastAPI** will do a lot of the work for you.

/// info

Het belangrijkste is dat door standaard Python types te gebruiken, op één plek (in plaats van meer klassen, decorators, enz. toe te voegen), **FastAPI** een groot deel van het werk voor je doet.

/// info

Điều quan trọng là bằng việc sử dụng các kiểu dữ liệu chuẩn của Python (thay vì thêm các lớp, decorators,...), **FastAPI** sẽ thực hiện nhiều công việc cho bạn.

 *  Fix: Don't crash when canceling an event source created by `EventSources.processResponse()`.
 *  New: `Cache` now has a public constructor that takes an [okio.FileSystem]. This should make it
    possible to implement decorators for cache encryption or compression.
 *  New: `Cookie.newBuilder()` to build upon an existing cookie.
 *  New: Use TLSv1.3 when running on JDK 8u261 or newer.

Umieszczasz to na szczycie funkcji. Jak ładną ozdobną czapkę (chyba stąd wzięła się nazwa).

"Dekorator" przyjmuje funkcję znajdującą się poniżej jego i coś z nią robi.

W naszym przypadku dekorator mówi **FastAPI**, że poniższa funkcja odpowiada **ścieżce** `/` z **operacją** `get`.

Jest to "**dekorator operacji na ścieżce**".

Możesz również użyć innej operacji:

* `@app.post()`
* `@app.put()`
