### *Path operations* with `APIRouter` { #path-operations-with-apirouter }

And then you use it to declare your *path operations*.

Use it the same way you would use the `FastAPI` class:

```Python hl_lines="6  11  16" title="app/routers/users.py"

/// tip

Prefer to use the `Annotated` version if possible.

```Python hl_lines="1"

You can also use `url_for()` inside of the template, and use it, for example, with the `StaticFiles` you mounted with the `name="static"`.

```jinja hl_lines="4"
{!../../docs_src/templates/templates/item.html!}
```

In this example, it would link to a CSS file at `static/styles.css` with:

```CSS hl_lines="4"
{!../../docs_src/templates/static/styles.css!}
```

которая поддерживает асинхронность. Для этого вам просто нужно объявить её как `async def`:

```Python hl_lines="1"
async def get_burgers(number: int):
    # Готовим бургеры по специальному асинхронному рецепту
    return burgers
```

...вместо `def`:

```Python hl_lines="2"
# Это не асинхронный код
def get_sequential_burgers(number: int):
    # Готовим бургеры последовательно по шагам

```Python hl_lines="1"
async def get_burgers(number: int):
    # Faz alguma coisa assíncrona para criar os hambúrgueres
    return burgers
```

...ao invés de `def`:

```Python hl_lines="2"
# Isso não é assíncrono
def get_sequential_burgers(number: int):

```Python hl_lines="1"
async def get_burgers(number: int):
    # burgerleri oluşturmak için asenkron birkaç iş
    return burgers
```

...`def` yerine:

```Python hl_lines="2"
# bu kod asenkron değil
def get_sequential_burgers(number: int):
    # burgerleri oluşturmak için senkron bırkaç iş

            }

            final Map<String, Object> doc = new HashMap<>();
            doc.put("doc_id", setting.get("doc_id"));
            doc.put("url", setting.get("url_link"));
            doc.put("title", setting.get("title"));
            doc.put("role", "Rguest");
            doc.put("boost", setting.get("boost"));
            //            doc.put("click_count", 100);  // Validation Error

```Python hl_lines="1"
async def get_burgers(number: int):
    # Opérations asynchrones pour créer les burgers
    return burgers
```

...et non `def` :

```Python hl_lines="2"
# Ceci n'est pas asynchrone
def get_sequential_burgers(number: int):
    # Opérations asynchrones pour créer les burgers
