Main Features

Redis and Memcached

The @cache() decorator caches responses with a configurable TTL via Redis or Memcached.

python 
from fastapi import FastAPI
from fastapi_cache import FastAPICache
from fastapi_cache.backends.redis import RedisBackend
from fastapi_cache.decorator import cache
from redis import asyncio as aioredis

app = FastAPI()

@app.on_event('startup')
async def startup():
    redis = aioredis.from_url('redis://localhost')
    FastAPICache.init(RedisBackend(redis), prefix='cache')

@app.get('/data')
@cache(expire=60)
async def get_data():
    return {'result': 'cached for 60s'}
