**FastAPI** provides the same `starlette.staticfiles` as `fastapi.staticfiles` just as a convenience for you, the developer. But it actually comes directly from Starlette.

### What is "Mounting" { #what-is-mounting }

"Mounting" means adding a complete "independent" application in a specific path, that then takes care of handling all the sub-paths.

///

### Qu'est-ce que « Mounting » { #what-is-mounting }

« Mounting » signifie ajouter une application complète « indépendante » sur un chemin spécifique, qui se chargera ensuite de gérer tous les sous-chemins.

**FastAPI**, geliştirici olarak size kolaylık olsun diye `starlette.staticfiles`'ı `fastapi.staticfiles` olarak da sağlar. Ancak aslında doğrudan Starlette'den gelir.

///

### "Mounting" Nedir { #what-is-mounting }

"Mounting", belirli bir path'te tamamen "bağımsız" bir uygulama eklemek ve sonrasında tüm alt path'leri handle etmesini sağlamak demektir.

If you need to have two independent FastAPI applications, with their own independent OpenAPI and their own docs UIs, you can have a main app and "mount" one (or more) sub-application(s).

## Mounting a **FastAPI** application { #mounting-a-fastapi-application }

"Mounting" means adding a completely "independent" application in a specific path, that then takes care of handling everything under that path, with the _path operations_ declared in that sub-application.

	// closes `doneCh` to indicate to caller to also exit.
	//
	// 2. If caller (Evaluate()) has an error, it sends an error
	// message and waits for this go-routine to quit in
	// FinishWithError()
	//
	// 3. If caller is done, it waits for this go-routine to exit
	// in Finish()

	quitFlag := false
	for !quitFlag {
		select {
		case data := <-writer.errCh:
			quitFlag = true

Now, you should be able to go to your docs at [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs), and reload the page, it will load those assets from the new CDN.

## Self-hosting JavaScript and CSS for docs { #self-hosting-javascript-and-css-for-docs }

Self-hosting the JavaScript and CSS could be useful if, for example, you need your app to keep working even while offline, without open Internet access, or in a local network.

	// dynamic sleeper to avoid thundering herd for trash folder expunge routine
	deleteCleanupSleeper = newDynamicSleeper(5, 25*time.Millisecond, false)

	// dynamic sleeper for multipart expiration routine
	deleteMultipartCleanupSleeper = newDynamicSleeper(5, 25*time.Millisecond, false)

	// Is MINIO_SYNC_BOOT set?
	globalEnableSyncBoot bool

/// note | 技术细节

你也可以用 `from starlette.staticfiles import StaticFiles`。

**FastAPI** 提供了和 `starlette.staticfiles` 相同的 `fastapi.staticfiles`，只是为了方便你这个开发者。但它确实直接来自 Starlette。

### 什么是“挂载”（Mounting） { #what-is-mounting }

“挂载”表示在特定路径添加一个完全“独立”的应用，然后负责处理所有子路径。

这与使用 `APIRouter` 不同，因为挂载的应用是完全独立的。主应用的 OpenAPI 和文档不会包含已挂载应用的任何内容，等等。

你可以在[高级用户指南](../advanced/index.md)中了解更多。
