npm install vue-translation-tool
You only need to install the plugin, pass your VuexStore instance in the options object and you're good to go!
import Vue from 'vue'
import store from './store' // import your VuexStore instance
import VueTranslationTool from 'vue-translation-tool'
Vue.use(VueTranslationTool, { store }))
in your template
<vue-translation-tool url="all.json"></vue-translation-tool>
you can pass an 'url' to a previous exported language file, this will be loaded when the component is mounted
