**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.

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.

O **FastAPI** fornece o mesmo que `starlette.staticfiles` como `fastapi.staticfiles` apenas como uma conveniência para você, o desenvolvedor. Mas na verdade vem diretamente da Starlette.

///

### O que é "Montagem" { #what-is-mounting }

"Montagem" significa adicionar uma aplicação completamente "independente" em um path específico, que então cuida de lidar com todos os sub-paths.

/// 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，开发者。但它确实来自Starlette。

///

### 什么是"挂载"(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，因为安装的应用程序是完全独立的。OpenAPI和来自你主应用的文档不会包含已挂载应用的任何东西等等。

你可以在**高级用户指南**中了解更多。

## 细节

**FastAPI** proporciona el mismo `starlette.staticfiles` como `fastapi.staticfiles` solo como una conveniencia para ti, el desarrollador. Pero en realidad viene directamente de Starlette.

///

### Qué es "Montar" { #what-is-mounting }

"Montar" significa agregar una aplicación completa "independiente" en un path específico, que luego se encargará de manejar todos los sub-paths.

It brings the same **developer experience** of building apps with FastAPI to **deploying** them to the cloud. 🎉
