Can you force Vue.js to reload/re-render?


Try this magic spell:

vm.$forceUpdate();

No need to create any hanging vars :)

Update: I found this solution when I only started working with VueJS. However further exploration proved this approach as a crutch. As far as I recall, in a while I got rid of it simply putting all the properties that failed to refresh automatically (mostly nested ones) into computed properties.

More info here: https://vuejs.org/v2/guide/computed.html


This seems like a pretty clean solution from matthiasg on this issue:

you can also use :key="someVariableUnderYourControl" and change the key when you want to component to be completely rebuilt

For my use case, I was feeding a Vuex getter into a component as a prop. Somehow Vuex would fetch the data but the reactivity wouldn't reliably kick in to rerender the component. In my case, setting the component key to some attribute on the prop guaranteed a refresh when the getters (and the attribute) finally resolved.


Please read thishttp://michaelnthiessen.com/force-re-render/

The horrible way: reloading the entire page
The terrible way:using the v-if hack
The better way: using Vue’s built-inforceUpdate method
The best way: key-changing on yourcomponent

<template>   <component-to-re-render :key="componentKey" /></template><script> export default {  data() {    return {      componentKey: 0,    };  },  methods: {    forceRerender() {      this.componentKey += 1;      }  } }</script>

I also use watch: in some situations.
