afn-redis-cache

A shared network cache for https://github.com/MatAtBread/afn to speed up clustered API servers

Installation

npm install --save afn-redis-cache

Usage

Require the module

var configureCache = require('afn-redis-cache') ;

Configure the cache and get a function to create caches with that configuration You can create multiple 'cacheCreators' with different configurations by calling configureCache() multiple times

var cacheCreator = configureCache({
	defaultTTL:60	// 1 minute by default
	redis:			// Any valid redis createClient parameter (see https://github.com/NodeRedis/node_redis/blob/master/README.md#options-object-properties)
		"redis":"redis://127.0.0.1:6379/13"		//eg. a 'redis_url'
}) ;

Now create a cache // "id" is an optional alphanumeric string prepended to cache entries, // so you can (on the same redis DB) create multiple caches that won't collide var cache = cacheCreator.createCache(id) ; Use the cache // Async cache API - a subset of a JavaScript Map API await cache.get(key); await cache.set(key,data,ttl); await cache.delete:(key); await cache.keys();
