Main.py file
async def bkapp_page(request: Request):
script = server_document('http://127.0.0.1:5000/app')
return templates.TemplateResponse("base.html", {"request": request, "script": script})
I have initialised the jinja template like below
templates = Jinja2Templates(directory="templates")
At the end of the file, I am using below code to render the plot in fastapi
pn.serve({'/app': createApp, '/app2': createApp2},
port=5000, allow_websocket_origin=["127.0.0.1:8000"],
address="127.0.0.1", show=False)
I followed the integration article FastAPI but Iām not getting the desired results.
Can someone please help ?
