How to convert timestamp to date format in vue2.0

<!-- value format is 13-bit unix timestamp --> 
<!-- 10-bit unix timestamp can be converted to 13-bit format by value*1000 -->

export function formatDate (date, fmt) {
    if (/(y+)/.test(fmt)) {
        fmt = fmt.replace(RegExp.$1, (date.getFullYear() + '').substr(4 - RegExp.$1.length));
    }
    let o = {
        'M+': date.getMonth() + 1,
        'd+': date.getDate(),
        'h+': date.getHours(),
        'm+': date.getMinutes(),
        's+': date.getSeconds()
    };
    for (let k in o) {
        if (new RegExp(`(${k})`).test(fmt)) {
            let str = o [k] + '' ;
            fmt = fmt.replace(RegExp.$1, (RegExp.$1.length === 1) ? str : padLeftZero(str));
        }
    }
    return fmt;
};

function padLeftZero (str) {
    return ('00' + str).substr(str.length);
};

 Save the above code as date.js and put it in your public js folder.

In your component that needs to format timestamps use like this:

<template>
    <!-- The filter time can make the data obtained in the background, and it can also be looped out -->
    <div>{{time | formatDate}}</div>
    <!-- output result-->
    <!-- <div>2016-07-23 21:52</div> -->
</template>
<script>
import {formatDate} from './common/date.js';
export default {
    filters: {
        formatDate(time) {
            var date = new Date(time);
            return formatDate(date, 'yyyy-MM-dd hh:mm');
        }
    }
}
</script>
