# Bigger Applications - Multiple Files { #bigger-applications-multiple-files }

If you are building an application or a web API, it's rarely the case that you can put everything in a single file.

**FastAPI** provides a convenience tool to structure your application while keeping all the flexibility.

If you come from Flask, this would be the equivalent of Flask's Blueprints.

## Scope

This Code of Conduct applies to all content on tensorflow.org, TensorFlow’s GitHub organization, or any other official TensorFlow web presence allowing for community interactions, as well as at all official TensorFlow events, whether offline or online.

# WebSockets { #websockets }

You can use [WebSockets](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API) with **FastAPI**.

## Install `websockets` { #install-websockets }

Make sure you create a [virtual environment](../virtual-environments.md), activate it, and install `websockets` (a Python library that makes it easy to use the "WebSocket" protocol):

<div class="termy">

```console
$ pip install websockets

---> 100%
```

* その後、`response` を返す前にさらに `response` を変更することもできます。

# WebSockets { #websockets }

你可以在 **FastAPI** 中使用 [WebSockets](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API)。

## 安裝 `websockets` { #install-websockets }

請先建立[虛擬環境](../virtual-environments.md)、啟用它，然後安裝 `websockets`（一個讓你更容易使用「WebSocket」通訊協定的 Python 套件）：

<div class="termy">

```console
$ pip install websockets

---> 100%
```

</div>

### Tech Stack

 * names is a distinct URL and they are not interchangeable. For example, even if
 * `http://square.github.io/dagger` and `http://google.github.io/dagger` are served by the same IP
 * address, the two URLs identify different resources.
 *
 * ### Port
 *
 * The port used to connect to the web server. By default this is 80 for HTTP and 443 for HTTPS.
