Starlette/FastAPI

htpy works great in combination with Starlette and FastAPI. htpy supports full async rendering of all components. See async rendering for more information.

Returning htpy content from a handler

To return HTML contents, use the HtpyResponse class:

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

from htpy import Element, h1
from htpy.starlette import HtpyResponse


async def index_component() -> Element:
    return h1["Hi Starlette!"]


async def index(request: Request) -> HtpyResponse:
    return HtpyResponse(index_component())


app = Starlette(
    routes=[
        Route("/", index),
    ]
)
