If you have an API that does a comparable amount of computations every time and you have a lot of clients, then the **CPU utilization** will probably *also be stable* (instead of constantly going up and down quickly).

### Examples of Replication Tools and Strategies

    "ignore:'cgi' is deprecated:DeprecationWarning",
    # For passlib
    "ignore:'crypt' is deprecated and slated for removal in Python 3.13:DeprecationWarning",
    # see https://trio.readthedocs.io/en/stable/history.html#trio-0-22-0-2022-09-28
    "ignore:You seem to already have a custom.*:RuntimeWarning:trio",
    "ignore::trio.TrioDeprecationWarning",
    # TODO remove pytest-cov

素晴らしいツールで、私も**FastAPI**を持つ前はよく使っていました。

    Webargsは、Marshmallowと同じ開発者により作られました。

    受信したデータに対する自動的なバリデーションを持っている点。

MarshmallowとWebargsはバリデーション、パース、シリアライゼーションをプラグインとして提供しています。

しかし、ドキュメントはまだ不足しています。そこでAPISpecが作られました。

これは多くのフレームワーク用のプラグインです (Starlette用のプラグインもあります) 。

## 0.69.0

### Breaking Changes - Upgrade

This release adds support for [Trio](https://trio.readthedocs.io/en/stable/). ✨

It upgrades the version of Starlette to `0.15.0`, now based on [AnyIO](https://anyio.readthedocs.io/en/stable/), and the internal async components in **FastAPI** are now based on AnyIO as well, making it compatible with both **asyncio** and **Trio**.

Starlette und **FastAPI** basieren auf <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a>, welches diese sowohl mit der Python-Standardbibliothek <a href="https://docs.python.org/3/library/asyncio-task.html" class="external-link" target="_blank">asyncio</a>, als auch mit <a href="https://trio.readthedocs.io/en/stable/" class="external-link" target="_blank">Trio</a> kompatibel macht.

When you run `fastapi dev`, it will run on development mode.

By default, it will have **auto-reload** enabled, so it will automatically reload the server when you make changes to your code. This is resource intensive and could be less stable than without it, you should only use it for development.

By default it will listen on the IP address `127.0.0.1`, which is the IP for your machine to communicate with itself alone (`localhost`).

## `fastapi run`
