# Hash

Wrap [Redis Hash](https://redis.io/commands#hash)

_Implements most used Redis commands, rest commands will implement during time or upon request_

---

**Example**

```javascript
let redisHash = new RedisHash('mykey');

await redisHash.set('field1', 'str1');
await redisHash.set('field2', {a: 5, b: 6});

// Same
await redisHash.set({
    field1: 'str1',
    field2: {a: 5, b: 6}
});

let data = await redisHash.get('field2');

// Will print {a: 5, b: 6}
console.log(data); 


data = await redisHash.getAll();

// Will print {field1: 'str1', field2: {a: 5, b: 6}}
console.log(data); 

```
