Utilizado pelo FastAPI / Starlette:

* <a href="https://www.uvicorn.org" target="_blank"><code>uvicorn</code></a> - para o servidor que carrega e serve a sua aplicação. Isto inclui `uvicorn[standard]`, que inclui algumas dependências (e.g. `uvloop`) necessárias para servir em alta performance.
* `fastapi-cli` - que disponibiliza o comando `fastapi`.

### Sem as dependências `standard`

`asyncio`に基づいた、Pythonのフレームワークの中でも非常に高速なものの一つです。Flaskと非常に似た作りになっています。

/// note | 技術詳細

Pythonの`asyncio`ループの代わりに、`uvloop`が利用されています。それにより、非常に高速です。

`Uvicorn`と`Starlette`に明らかなインスピレーションを与えており、それらは現在オープンなベンチマークにおいてSanicより高速です。

物凄い性能を出す方法を見つけた点。

Used by FastAPI:

* <a href="https://www.uvicorn.org" target="_blank"><code>uvicorn</code></a> - for the server that loads and serves your application. This includes `uvicorn[standard]`, which includes some dependencies (e.g. `uvloop`) needed for high performance serving.
* `fastapi-cli[standard]` - to provide the `fastapi` command.

### Breaking changes

* ⬆️ Upgrade Uvicorn when installing `fastapi[all]` to the latest version including `uvloop`, the new range is `uvicorn[standard] >=0.12.0,<0.14.0`. PR [#2548](https://github.com/tiangolo/fastapi/pull/2548) by [@tiangolo](https://github.com/tiangolo).

### Fixes

Se você se deparar com um `RuntimeError: Task attached to a different loop` ao integrar funções assíncronas em seus testes (e.g. ao utilizar o <a href="https://stackoverflow.com/questions/41584243/runtimeerror-task-attached-to-a-different-loop" class="external-link" target="_blank">MotorClient do MongoDB</a>) Lembre-se de instanciar objetos que precisam de um loop de eventos (*event loop*) apenas em funções assíncronas, e.g. um *"callback"* `'@app.on_event("startup")`.

/// tip

If you encounter a `RuntimeError: Task attached to a different loop` when integrating asynchronous function calls in your tests (e.g. when using <a href="https://stackoverflow.com/questions/41584243/runtimeerror-task-attached-to-a-different-loop" class="external-link" target="_blank">MongoDB's MotorClient</a>), remember to instantiate objects that need an event loop only within async functions, e.g. an `'@app.on_event("startup")` callback.

tip | Tipp

Wenn Sie einen `RuntimeError: Task attached to a different loop` erhalten, wenn Sie asynchrone Funktionsaufrufe in Ihre Tests integrieren (z. B. bei Verwendung von <a href="https://stackoverflow.com/questions/41584243/runtimeerror-task-attached-to-a-different-loop" class="external-link" target="_blank">MongoDBs MotorClient</a>), dann denken Sie daran, Objekte zu instanziieren, die einen Event Loop nur innerhalb asynchroner Funktionen benötigen, z. B. einen `@app.on_event("startup")`-Callback....
