## Клієнт WebSockets { #websockets-client }

### У продакшені { #in-production }

У вашій продакшен-системі у вас, напевно, є фронтенд, створений за допомогою сучасного фреймворку на кшталт React, Vue.js або Angular.

Для спілкування через WebSockets з бекендом ви, ймовірно, використовуватимете утиліти вашого фронтенду.

## Reduce duplication { #reduce-duplication }

Reducing code duplication is one of the core ideas in **FastAPI**.

	tillOffset int64           // Affects the length of data requested in disk.ReadFile depending on Read()'s offset
	buf        []byte          // Holds bit-rot verified data
}

func (b *wholeBitrotReader) ReadAt(buf []byte, offset int64) (n int, err error) {
	if b.buf == nil {
		b.buf = make([]byte, b.tillOffset-offset)
		if _, err := b.disk.ReadFile(context.TODO(), b.volume, b.filePath, offset, b.buf, b.verifier); err != nil {

// read to be handled correctly. On the other hand, a change to the file size
// (st_size, as made by say ftruncate(2)), would require a metadata flush.
//
// The aim of fdatasync() is to reduce disk activity for applications that
// do not require all metadata to be synchronized with the disk.
func Fdatasync(f *os.File) error {
	return syscall.Fdatasync(int(f.Fd()))
}

// FadviseDontNeed invalidates page-cache

## Cliente WebSockets { #websockets-client }

### En producción { #in-production }

En tu sistema de producción, probablemente tengas un frontend creado con un framework moderno como React, Vue.js o Angular.

Y para comunicarte usando WebSockets con tu backend probablemente usarías las utilidades de tu frontend.

<div class="termy">

```console
$ pip install websockets

## WebSockets 客户端 { #websockets-client }

### 在生产环境中 { #in-production }

在您的生产系统中，您可能使用现代框架（如 React、Vue.js 或 Angular）创建了一个前端。

要使用 WebSockets 与后端进行通信，您可能会使用前端的工具。

或者，您可能有一个原生移动应用程序，直接使用原生代码与 WebSocket 后端通信。

或者，您可能有其他与 WebSocket 终端通信的方式。

但是，在本示例中，我们将使用一个非常简单的 HTML 文档，其中包含一些 JavaScript，全部放在一个长字符串中。
