# cacheman-redis

[![Build Status](https://travis-ci.org/cayasso/cacheman-redis.png?branch=master)](https://travis-ci.org/cayasso/cacheman-redis)
[![NPM version](https://badge.fury.io/js/cacheman-redis.png)](http://badge.fury.io/js/cacheman-redis)

Redis standalone caching library for Node.JS and also cache engine for [cacheman](https://github.com/cayasso/cacheman).

## Instalation

``` bash
$ npm install cacheman-redis
```

## Usage

```javascript
var CachemanRedis = require('cacheman-redis');
var cache = new CachemanRedis();

// set the value
cache.set('my key', { foo: 'bar' }, function (error) {

if (error) throw error;

// get the value
  cache.get('my key', function (error, value) {

if (error) throw error;

console.log(value); //-> {foo:"bar"}

// delete entry
    cache.del('my key', function (error){

if (error) throw error;

console.log('value deleted');
    });

});
});
```

## API

### CachemanRedis([options])

Create `cacheman-redis` instance. `options` are redis valid options including `port` and `host`.

```javascript
var options = {
  port: 9999,
  host: '127.0.0.1',
  password: 'my-p@ssw0rd'
  database: 1
};

var cache = new CachemanRedis(options);
```

You can also pass a redis connection string as first arguments like this:

```javascript
var cache = new CachemanRedis('redis://127.0.0.1:6379');
```

Or pass a redis `client` instance directly as client:

```javascript
var client = redis.createClient();

var cache = new CachemanRedis(client);

// or
cache = new CachemanRedis({ client: client });
```

### cache.set(key, value, [ttl, [fn]])

Stores or updates a value.

```javascript
cache.set('foo', { a: 'bar' }, function (err, value) {
  if (err) throw err;
  console.log(value); //-> {a:'bar'}
});
```

Or add a TTL(Time To Live) in seconds like this:

```javascript
// key will expire in 60 seconds
cache.set('foo', { a: 'bar' }, 60, function (err, value) {
  if (err) throw err;
  console.log(value); //-> {a:'bar'}
});
```

### cache.get(key, fn)

Retrieves a value for a given key, if there is no value for the given key a null value will be returned.

```javascript
cache.get(function (err, value) {
  if (err) throw err;
  console.log(value);
});
```

### cache.del(key, [fn])

Deletes a key out of the cache.

```javascript
cache.del('foo', function (err) {
  if (err) throw err;
  // foo was deleted
});
```

### cache.clear([fn])

Clear the cache entirely, throwing away all values.

```javascript
cache.clear(function (err) {
  if (err) throw err;
  // cache is now clear
});
```

### cache.scan(cursor, count, [fn])

[Scan](https://redis.io/commands/scan) cache from a cursor point and return a count of values

```javascript
cache.set('foo', { a: 'bar' }, 10, function (err) {
  cache.scan(0, 10, function (err, result) {
    console.log(result) // { cursor: 0, entries: [{ key: 'foo', data: { a: 'bar' } }] }
  });
});
````
