Check if vuex-persist has restored data in Nuxt project - vue.js

Question

I have added Vuex-Persist and Vuex-ORM to my Nuxt project. When the application starts for the first time I want to add some boilerplate data.
In my default.vue layout I have added a created function to add this dummy data.
<script>
import Project from '../models/Project';
export default {
created () {
// I'm Using Vuex-Orm to check if there are any projects stored
if (Project.query().count() === 0) {
Project.insert({ data: [{ title: 'My first project' }] })
}
}
}
</script>
When the application is reloaded and opens for the second time, I would expect that Project.query().count()
returns 1. But it will always return 0 because vuex-persist isn't done restoring the local data yet.
According to the docs this would be the solution
import { store } from '#/store' // ...or wherever your `vuex` store is defined
const waitForStorageToBeReady = async (to, from, next) => {
await store.restored
next()
}
store.defined is undefined and same goes for this.$store.
That comment highlights my exact question "Where is my vuex store defined?"

Answer 1

i think you have to put the whole thing in a route guard.
create a route-guard.js plugin like this. but I haven't tested the whole thing, hope it helps you further.
export default function ({app}) {
const waitForStorageToBeReady = async (to, from, next) => {
await store.restored
next()
}
app.router.beforeEach(waitForStorageToBeReady);
}
Another option is to put a getter in computed and watch it:
export default {
computed: {
persistState() {
return this.store.getter['get_persis_state'];
}
},
watch: {
persistState(newVal) {
// check new val
}
}
}

I followed the instructions from vuex-persist for Nuxt and made a plugin file, like this:
// ~/plugins/vuex-persist.js
import VuexPersistence from 'vuex-persist'
export default ({ store }) => {
window.onNuxtReady(() => {
new VuexPersistence({
/* your options */
}).plugin(store);
});
}
window.onNuxtReady caused the plugin to be loaded after all other code had run. So I didn't matter if I made a router-guard.js plugin or tried it in the layout/default.vue file.
I ended up with the quick fix:
// ~/plugins/vuex-persist.js
import VuexPersistence from 'vuex-persist'
export default ({ store }) => {
window.onNuxtReady(() => {
new VuexPersistence().plugin(store);
if (Project.query().count() === 0) {
Project.insert({ data: [{ title: 'My first project' }] })
}
});
}
