from collections.abc import AsyncIterator
from contextlib import asynccontextmanager
from typing import TypedDict

import httpx

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


class State(TypedDict):
    http_client: httpx.AsyncClient


@asynccontextmanager
async def lifespan(app: Starlette) -> AsyncIterator[State]:
    async with httpx.AsyncClient() as client:
        yield {"http_client": client}


async def homepage(request: Request[State]):
    client = request.state["http_client"]
    # If you run the below line with mypy or pyright, it will reveal the correct type.
    reveal_type(client)  # Revealed type is 'httpx.AsyncClient'
