redis-client 0.2.0

A simple client for Redis

Redis client

Simple Redis client for python.

It has been made to simplify working with Redis in python.

Usage

Instantiate Cache(), give the Redis host, port and db.

Then you can get a cached entry with Cache.get_data_from_cache() and add an entry to Redis with Cache.save_data_to_cache()

⚠️The data send to cache NEEDS TO BE A DICTIONARY! ⚠️

Code example

from redis_client.client import Cache
from time import sleep
from tpying import Dict

cache = Cache(redis_host="localhost", redis_port=6379, redis_db=0, log_level="INFO")

def username_expander(username: str) -> Dict[str, str]:
    """Example of a function that require caching."""
    # Key that will be use to retrieve cached data
    # Note that I include the parameter 'username' in the key to make sure we only cache unique value.
    key = f"username_expander:{username}"
    # Check if the data is already caches
    cached_data = cache.get_data_from_cache(key)
    # Return it if yes
    if cached_data:
        return cached_data
    
    sleep(10)
    data = {"expanded_username": f"{username}_123"}
    # Save data to cache with an expiration time of 12 hours
    cache.save_data_to_cache(key, data, expiration_in_hours=12)
    return data
