Header Parameters - FastAPI
 FastAPI framework, high performance, easy to learn, fast to code, ready for production

Getting request headers in fastapi has a pretty nice stetup, it allows you to get headers values as function arguments,

I was able to use headers to detect if a request was made from htmx or not.

> If the request was made from htmx, then we want a html format, otherwise I'm probably hitting the api programatically from something like `curl` or `python`

``` python
@post_router.post("/post/")
async def post_post(
 request: Request,
 post: PostCreate,
 current_user: Annotated[User, Depends(try_get_current_active_user)],
 session: Session = Depends(get_session),
 is_hx_request: Annotated[str | None, Header()] = None,
) -> PostRead:
 "create a post"
 print('hx_request', hx_request)
 db_post = Post.from_orm(post)
 session.add(db_post)
 session.commit()
 session.refresh(db_post)
 if is_hx_request:
 return templates.TemplateResponse("post_item.html", {"request": request, "config": config, "post": db_post})
 return db_post

```
