### Generate a TypeScript Client with Tags

If you generate a client for a FastAPI app using tags, it will normally also separate the client code based on the tags.

### Flask REST frameworks

There are several Flask REST frameworks, but after investing the time and work into investigating them, I found that many are discontinued or abandoned, with several standing issues that made them unfit.

### Run Automatically on Startup

In general, you will probably want the server program (e.g. Uvicorn) to be started automatically on server startup, and without needing any **human intervention**, to have a process always running with your API (e.g. Uvicorn running your FastAPI app).

* Review those pull requests, requesting changes or approving them. For the languages I don't speak, I'll wait for several others to review the translation before merging.

### Generic-типи з параметрами типів

Існують деякі структури даних, які можуть містити інші значення, наприклад `dict`, `list`, `set` та `tuple`. І внутрішні значення також можуть мати свій тип.

Ці типи, які мають внутрішні типи, називаються "**generic**" типами. І оголосити їх можна навіть із внутрішніми типами.

#### Generic-типы

Эти типы принимают параметры в квадратных скобках:

* `List`
* `Tuple`
* `Set`
* `Dict`
* `Optional`
* ...и др.

называются **Generic-типами** или **Generics**.

### Классы как типы

Вы также можете объявить класс как тип переменной.

                """
            ),
        ],
        scope: Annotated[
            str,
            Form(),
            Doc(
                """
                A single string with actually several scopes separated by spaces. Each
                scope is also a string.

                For example, a single string with:

                ```python

{!../../../docs_src/path_params/tutorial005.py!}
```

#### Récupérer la *valeur de l'énumération*

Vous pouvez obtenir la valeur réel d'un membre (une chaîne de caractères ici), avec `model_name.value`, ou en général, `votre_membre_d'enum.value` :

```Python hl_lines="20"
{!../../../docs_src/path_params/tutorial005.py!}
```

!!! tip "Astuce"
    Vous pouvez aussi accéder la valeur `"lenet"` avec `ModelName.lenet.value`.

For example:

```Python hl_lines="4-7"
{!../../../docs_src/behind_a_proxy/tutorial003.py!}
```

Will generate an OpenAPI schema like:

```JSON hl_lines="5-7"
{
    "openapi": "3.1.0",
    // More stuff here
    "servers": [
        {
            "url": "/api/v1"
        },
        {

And there are dozens of alternatives, all based on OpenAPI. You could easily add any of those alternatives to your application built with **FastAPI**.

You could also use it to generate code automatically, for clients that communicate with your API. For example, frontend, mobile or IoT applications.
