Moment directive for Vue.js http://codepen.io/pespantelis/pen/oLLLMP

moment-ago.js

import Vue from 'vue'
import Moment from 'moment'

Vue.directive('moment-ago', {
  update (timestamp) {
    this.el.innerHTML = Moment(timestamp).fromNow()

    this.interval = setInterval(() => {
      this.el.innerHTML = Moment(timestamp).fromNow()
    }, 1000)
  },

  unbind () {
    clearInterval(this.interval)
  }
})

But still have problem, if use vue-router and setting keep-alive mode, inactive component still keep update
