## 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.

from typing import List

from fastapi import FastAPI
from fastapi.routing import APIRoute
from pydantic import BaseModel


def custom_generate_unique_id(route: APIRoute):
    return f"{route.tags[0]}-{route.name}"


app = FastAPI(generate_unique_id_function=custom_generate_unique_id)


class Item(BaseModel):
    name: str
    price: float


class ResponseMessage(BaseModel):
    message: str

{"name":"Michael", "age": 31}
{"name":"Andy", "age": 30}

    - port: 80
      targetPort: 8080
      name: http2
    - port: 443
      targetPort: 8443
      name: https
    - port: 31400
      targetPort: 31400
      name: tcp
      # This is the port where sni routing happens
    - port: 15443
      targetPort: 15443
      name: tls
    resources:
      requests:
        cpu: 10m

```

!!! 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。
