How to add context to HTMLResponse?

Question

How to add context to HTMLResponse as you can do with TemplateResponse to insert content into the HTML site? Example with TemplateResponse:

return templates.TemplateResponse('index.html', context={'request': request, "Variable1": V1, "Variable2": V2})

And how to add the context here?:

@app.get("/")
def root():
    return HTMLResponse(pkg_resources.resource_string(__name__, "index.html"))

You can use jinja to achieve solution to your problem.

from fastapi import FastAPI, Request
from fastapi.responses import HTMLResponse
from fastapi.staticfiles import StaticFiles
from fastapi.templating import Jinja2Templates

app = FastAPI()

app.mount("/static", StaticFiles(directory="static"), name="static")


templates = Jinja2Templates(directory="templates")


@app.get("/items/{id}", response_class=HTMLResponse)
async def read_item(request: Request, id: str):
    context = {'request': request, "Variable1": V1, "Variable2": V2}
    return templates.TemplateResponse("item.html", context)
