(Vue.js) Same component with different routes

You can use watch property, so your component will not waste time to reloading:

index.js You might have something like this

const routes = [
  {
    path: '/users/:id',
    component: Vue.component('user', require('./comp/user.vue').default)
  }
]

user.vue

created(){
  // will fire on component first init
  this.init_component();
},
watch: {
  // will fire on route changes
//'$route.params.id': function(val, oldVal){ // Same
  '$route.path': function(val, oldVal){
    console.log(this.$route.params.id);
    this.init_component();
  }
},
methods: {
  init_component: function(){
    // do anything you need
    this.load_user_data_with_ajax();
  },
}

This is expected behaviour as Vue is trying to be optimal and reuse existing components. The behaviour you want to achieve used to be solved with a setting called canReuse, but that has been deprecated. The current recommended solution is to set a unique :key property on your <router-view> like so:

<router-view :key="$route.path"></router-view>

Just to make a note. If anybody is working with SSR template, things are a bit different. @mzgajner's answer does indeed recreate the component but will not trigger the asyncData again.

For that to happen, modify entry-client.js like this.

OLD:

const activated = matched.filter((c, i) => {
    return diffed || (diffed = (prevMatched[i] !== c))
})

NEW:

const activated = matched.filter((c, i) => {

    /*
        In my case I only needed this for 1 component
    */

    diffed = ((prevMatched[i] !== c) || c.name == 'p-page-property-map')

    return diffed
})
