Integrating with Starlette

markupy can be used with Starlette to generate HTML. Since FastAPI is built upon Starlette, markupy can also be used with FastAPI.

To return HTML contents, pass a markupy element to Starlette's HTMLResponse:

from starlette.applications import Starlette
from starlette.requests import Request
from starlette.responses import HTMLResponse
from starlette.routing import Route

from markupy.elements import H1, Body, Html


async def index(request: Request) -> HTMLResponse:
    return HTMLResponse(Html[Body[H1["Hi Starlette!"]]])


# Run it with `uv run uvicorn html_response:app``
app = Starlette(
    routes=[Route("/", index)],
)
