# moment-cache

### Moment-cache is a tiny tool to speed up your moment.js calls.

During the app lifecycle we can call moment oftentimes. Every call is time. Time is **performance**. This tool will increase performance of your app by **caching moment.js instances**.

### Why?

```javascript

  import moment from 'moment';

  import cache  from 'moment-cache';

  const dateString = '2016-08-24';

  const momentCalls = 99999;

  const check = (instance) => {

    let i = 0;

    const start = new Date;

    while (i <= momentCalls) {

      instance(dateString);

      i++;

    }

    return new Date - start;

  }

  console.log(check(moment));    // ~1588 ms

  console.log(check(cache));     // ~35 ms

```

### Syntax: 

#### Arguments:

 

* date: See [moment/parse](http://momentjs.com/docs/#/parsing/).

* format: See [moment/format](http://momentjs.com/docs/#/parsing/string-format/).

* clone (by default - **true**): set *false* if you are not going to change instance in future. Will increase performance, but any object changes will affect cached result. See [moment/clone](http://momentjs.com/docs/#/parsing/moment-clone/).

```javascript

  import cache from 'moment-cache'; // or moment().cache

  const myDate = '06-28-2016';

  const format = 'MM-DD-YYYY';

  const date = cache(myDate, format); // moment.js cached instance

  const anotherDate = cache(myDate, format); // rapidly retrieving previously processed result from the cache

```

  

#### Methods:

**updateStorage**: change cache destination.  

 

###### **Arguments**:

* **storage**: object where cache data is stored. By default - covert object behind the scenes.

```javascript

  import cachable from 'moment-cache';

  const myStorage = {};

  cachable.updateStorage(myStorage);

  const date = cachable('2016-08-23');

  console.log(myStorage); // {1471899600000: Moment}

```
