Codacy Badge License PyPi Version Downloads Build Status

Implements simple lightweight cache system as dependencies in FastAPI.

Installation

Usage example

from fastapi import Depends, FastAPI

from fastapi_cache import caches, close_caches
from fastapi_cache.backends.redis import CACHE_KEY, RedisCacheBackend

app = FastAPI()


def redis_cache():
    return caches.get(CACHE_KEY)


@app.get('/')
async def hello(
    cache: RedisCacheBackend = Depends(redis_cache)
):
    in_cache = await cache.get('some_cached_key')
    if not in_cache:
        await cache.set('some_cached_key', 'new_value', 5)

    return {'response': in_cache or 'default'}


@app.on_event('startup')
async def on_startup() -> None:
    rc = RedisCacheBackend('redis://redis')
    caches.set(CACHE_KEY, rc)


@app.on_event('shutdown')
async def on_shutdown() -> None:
    await close_caches()

Changelog

  • 0.0.6 Added typings for backends. Specific arguments now need to be passed through **kwargs. Set default encoding to utf-8 for redis backend, removed default TTL for redis keys.
Comments
  • Add support for caching generic types

    None

    What does this implement/fix?

    The current version of the package fails to retrieve objects in Redis that cannot be decoded by the default encoding='utf-8' option defined on get. In order to enable a more generic approach this PR refactor the Cache classes changing the value typing (both when setting and when retrieving) to Any, minimizing IDE's warnings, and adds a new optional parameter encoding to RedisCacheBackend.get method, keeping utf-8 as the default value to enable backwards compatibility. A new simple test for the option encoding=None was added.

  • Add support for Redis backend requiring TLS

    Add support for Redis backend requiring TLS

    It looks like the RedisCacheBackend doesn't support specifying the ssl passthrough option to aioredis.create_redis_pool() in order to be able to connect to a Redis endpoint that requires TLS, e.g. ElastiCache in AWS.

  • Create expire function

    Create expire function

    This PR will include the aioredis function for expire(key, timeout) in order to automatically invalidate an entry after some time. This is useful when using redis for caching API responses.

  • Add redis function to check if key exists or not

    Add redis function to check if key exists or not

    in our current implementation of redis we use exists a lot to check if a key is already set or not and then decide what to do.

    exists can check multiple keys at once and returns an integer with the number of existing keys.

  • How to pass a KEYS pattern when get cache [Redis Backend]?

    How to pass a KEYS pattern when get cache [Redis Backend]?

    Hi guys, I couldn't find anywhere how I can get values from a given key with a pattern. Eg.: project_* where * can be any char.

    I tried something like await cache.get("project_*") but no success.

    • poo_min_size is dropped, the connection pool is now lazy filled, not pre-filled
    • whether decode or not is decided globally, could not be changed on each top level api (like Redis.get())
