# Plantillas { #templates }

Puedes usar cualquier motor de plantillas que desees con **FastAPI**.

Una elección común es Jinja2, el mismo que usa Flask y otras herramientas.

Hay utilidades para configurarlo fácilmente que puedes usar directamente en tu aplicación de **FastAPI** (proporcionadas por Starlette).

## Instala dependencias { #install-dependencies }

}

### Установка `root_path` в приложении FastAPI { #setting-the-root-path-in-the-fastapi-app }

Если нет возможности передать опцию командной строки `--root-path` (или аналог), вы можете указать параметр `root_path` при создании приложения FastAPI:

{* ../../docs_src/behind_a_proxy/tutorial002_py39.py hl[3] *}

Передача `root_path` в `FastAPI` эквивалентна опции командной строки `--root-path` для Uvicorn или Hypercorn.
