I have had several problems with flow.
I would like to access the localStorage (plugin) inside router / index.js for example.

But the quasar load Router and then loads the Plugins, thus being Vue.localStorage be undefined :/.

plugins/localStorage.js

import VueLocalStorage from 'vue-localstorage'

export default ({ app, router, Vue }) => {

  Vue.use(VueLocalStorage)

}

router/index.js

import Vue from 'vue'
import VueRouter from 'vue-router'

import routes from './routes'

Vue.use(VueRouter)

const Router = new VueRouter({
  /*
   * NOTE! Change Vue Router mode from quasar.conf.js -> build -> vueRouterMode
   *
   * If you decide to go with "history" mode, please also set "build.publicPath"
   * to something other than an empty string.
   * Example: '/' instead of ''
   */

  // Leave as is and change from quasar.conf.js instead!
  mode: process.env.VUE_ROUTER_MODE,
  base: process.env.VUE_ROUTER_BASE,
  scrollBehavior: () => ({ y: 0 }),
  routes
})

Router.beforeEach((to, from, next) => {
  Vue.localStorage.set('teste', 'teste')
  next()
})

export default Router

I need to access localStorage to check if a saved token exists, and if there is user information look for on the server.

@rstoenescu Oh, my bad.

I had added in components. Now I’ve got it, and it’s working.

Many thanks for the support offered
