src

Simple Redis Cache

###Usage

src takes one hash parameter with url and expiry defined. Expiry is the number of seconds a value is non expired in Redis.

1var src = require('src');
2var cache = src(
3  {
4    url:'redis://user:password@example.com:9073/'
5    ,expiry:2
6  }
7);

Callbacks for set are optional

1cache.set('key', 'value', [cb]);

get requires a callback

1cache.get('key', function(err, value){
2  if(typeof value !== 'undefined')
3    console.log(value);
4});

If the key has expired, err will not be used to determine this. Err will only be a non null value when an error is thrown from Redis.

If you want to delete a key from the cache explicity src provides this functionality through cache.del

Callbacks are optional for del

1cache.del('key', [cb]);
