### 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.

This way you will be able to have things ordered and grouped correctly for the client code:

In this case you have:

* `ItemsService`
* `UsersService`

### Client Method Names

## Order matters

When creating *path operations*, you can find situations where you have a fixed path.

Like `/users/me`, let's say that it's to get data about the current user.

And then you can also have a path `/users/{user_id}` to get data about a specific user by some user ID.

dont vous bénéficierez de tous les avantages. Vous savez donc que vous êtes entre de bonnes mains.

## L'ordre importe

Quand vous créez des *fonctions de chemins*, vous pouvez vous retrouver dans une situation où vous avez un chemin fixe.

Tel que `/users/me`, disons pour récupérer les données sur l'utilisateur actuel.

Everyone before you is waiting for their burgers to be ready before leaving the counter because each of the 8 cashiers goes and prepares the burger right away before getting the next order.

Then it's finally your turn, you place your order of 2 very fancy burgers for your crush and you.

`threading.local` creates a value exclusive to the current thread, but an async framework would run all the code (e.g. for each request) in the same thread, and possibly not in order.

On top of that, an async framework could run some sync code in a threadpool (using `asyncio.run_in_executor`), but belonging to the same request.

                in the *path operations*, like:

                * `@app.get("/users/", tags=["users"])`
                * `@app.get("/items/", tags=["items"])`

                The order of the tags can be used to specify the order shown in
                tools like Swagger UI, used in the automatic path `/docs`.

                It's not required to specify all the tags used.

    Então, você deve declará-lo com `...` para marcá-lo como obrigatório.

    Mesmo que você declare-o como `None` ou defina um valor padrão, isso não teria efeito algum, o parâmetro ainda seria obrigatório.

## Ordene os parâmetros de acordo com sua necessidade

Suponha que você queira declarar o parâmetro de consulta `q` como uma `str` obrigatória.
