## Example Usage

#### set global config
```
// 30 day after, expire
this.$cookies.config('30d')

this.$cookies.config(new Date(2019,03,13).toUTCString())

// 30 day after, expire, '' current path , browser default

// window object
window.$cookies.config('30d')
```

#### support json object
```
var user = { id:1, name:'Journal',session:'25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX' };
this.$cookies.set('user',user);
// print user name
console.log(this.$cookies.get('user').name)
```

#### set expire times
**Suppose the current time is : Sat, 11 Mar 2017 12:25:57 GMT**

**Following equivalence: 1 day after, expire**

**Support chaining sets together**
``` javascript
 // default expire time: 1 day
this.$cookies.set("user_session","25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX")
        // number + d , ignore case
        .set("user_session","25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX","1d")
        .set("user_session","25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX","1D")
        // Base of second
        .set("user_session","25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX",60 * 60 * 24)
        // input a Date, + 1day
        .set("user_session","25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX", new Date(2017, 03, 12))
        // input a date string, + 1day
        .set("user_session","25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX", "Sat, 13 Mar 2017 12:25:57 GMT")
```
#### set expire times, input number type

```
this.$cookies.set("default_unit_second","input_value",1);            // 1 second after, expire
this.$cookies.set("default_unit_second","input_value",60 + 30);      // 1 minute 30 second after, expire
this.$cookies.set("default_unit_second","input_value",60 * 60 * 12); // 12 hour after, expire
this.$cookies.set("default_unit_second","input_value",60 * 60 * 24 * 30); // 1 month after, expire
```

#### set expire times - end of browser session

```
this.$cookies.set("default_unit_second","input_value",0);          // end of session - use 0 or "0"!
```
