!!! tip
    The "PATCH" is the last number, for example, in `0.2.3`, the PATCH version is `3`.

So, you should be able to pin to a version like:

```txt
fastapi>=0.45.0,<0.46.0
```

Breaking changes and new features are added in "MINOR" versions.

!!! tip
    The "MINOR" is the number in the middle, for example, in `0.2.3`, the MINOR version is `2`.

des changements rétrocompatibles.

!!! tip "Astuce"
    Le "PATCH" est le dernier chiffre, par exemple, dans `0.2.3`, la version PATCH est `3`.

Donc, vous devriez être capable d'épingler une version comme suit :

```txt
fastapi>=0.45.0,<0.46.0
```

Les changements non rétrocompatibles et les nouvelles fonctionnalités sont ajoutés dans les versions "MINOR".

!!! tip
    Notice the auto-generated server with a `url` value of `/api/v1`, taken from the `root_path`.

In the docs UI at <a href="http://127.0.0.1:9999/api/v1/docs" class="external-link" target="_blank">http://127.0.0.1:9999/api/v1/docs</a> it would look like:

But the rest of the session code is more or less the same, we just copy it.

```Python hl_lines="8-13"
{!../../../docs_src/sql_databases/sql_app/tests/test_sql_app.py!}
```

!!! tip
    You could reduce duplication in that code by putting it in a function and using it from both `database.py` and `tests/test_sql_app.py`.

    For simplicity and to focus on the specific testing code, we are just copying it.

As **FastAPI** is based on the **ASGI** standard, it's very easy to integrate any **GraphQL** library also compatible with ASGI.

You can combine normal FastAPI *path operations* with GraphQL on the same application.

!!! tip
    **GraphQL** solves some very specific use cases.

    It has **advantages** and **disadvantages** when compared to common **web APIs**.

You can import it directly from `fastapi`:

```python
from fastapi import Request
```

!!! tip
    When you want to define dependencies that should be compatible with both HTTP and WebSockets, you can define a parameter that takes an `HTTPConnection` instead of a `Request` or a `WebSocket`.

If something seems interesting and useful to your project, go ahead and check it, but otherwise, you might probably just skip them.
