cache-client

This is a caching api that allows you to connect to redis, memcached, or lru-cache. This utilizes the npm modules lru-cache, redis, or memcached. I have required them as dependencies so that they are installed with cache-client.

I started this project so that I could have an easy way to interact with each cache mechanism, using a single api. This made it easy to use between multiple environments and multiple projects. Now Supports all three cache stores. Added TTL support for Redis and Memcached, and LRU-cache.

The TTL for LRU is a bit experimental, I haven't tested it yet with the other lru-cache options.

Added in prefix support: config.prefix = "your_prefix_here"; will prefix all keys no matter the store.

Initialization

config = {store: "redis", port:6379, host:"127.0.0.1", opts:{}, auth:"password"};
config = {store: "memory", opts:{}};
config = {store: "memcached", host:"localhost:11211", opts:{}};
var cacheClient = require("cache-client");
cacheClient.setup(config);

Usage

Normal Methods

cacheClient.read("foo", function(result)
{
	//do something here
});

cacheClient.write("foo", "bar");

Advanced Methods You have access to the underlying modules(redis,memcached, lru) by calling cacheClient.client.method();

cacheClient.client.keys();
cacheClient.client.values();

cacheClient.client.some_redis_method();
cacheClient.client.some_memcached_method();

API

• write(key,value,ttl) if ttl is not provided, then it will default to 0, which will cache the item until it is cleared.

• read(key, callback(result))

• remove(key)

• clear() -> must be careful with this, this will flush the entire cache, so if you are using the same store for both sessions and cache or multiple apps use the same store, this will clear everything.
