FastAPI Decorator to cache function

you can use cache method as decorator between router decorator and view function and must pass request as param of view function.

from fastapi import FastAPI, Request
from fastapi.templating import Jinja2Templates
from fastapi.responses import HTMLResponse, PlainTextResponse
from detacache import FastAPICache

app = FastAPI()

templates = Jinja2Templates(directory='templates')

deta = FastAPICache(projectKey='projectKey')


@app.get('/t-html')
@deta.cache(expire=10)
def templateResponse(request:Request):
    return templates.TemplateResponse('home.html',context={'request':request})

@app.get('/html')
@deta.cache(expire=10)
