I am trying to use Vuex Store in my layout but can't figure out how to make it work.
Here is what I am doing:
store/sources.ts
import { VuexModule, Module, Mutation, Action } from 'vuex-module-decorators'
import { store } from '#/store'
import axios from 'axios'
const { sourcesEndpoint } = process.env
interface Source {
id: String
}
#Module({
name: 'sources',
namespaced: true,
stateFactory: true,
dynamic: true,
store,
})
export default class Sources extends VuexModule {
private _sources: Source[] = []
get sources(): Source[] {
return this._sources
}
#Mutation
updateSources(sources: Source[]) {
this._sources = sources
}
#Action({ commit: 'updateSources' })
async fetchSources() {
// eslint-disable-next-line no-console
console.log(`!!! ${sourcesEndpoint} !!!`)
return sourcesEndpoint ? await axios.get(sourcesEndpoint) : []
}
}
store/index.ts
import { Store } from 'vuex'
export const store = new Store({})
layouts/default.vue
<script>
import { getModule } from 'vuex-module-decorators'
import Sources from '#/store/sources'
export default {
fetch() {
const sourcesModule = getModule(Sources, this.$store)
sourcesModule.fetchSources()
},
fetchOnServer: false,
}
</script>
And the error I get:
[vuex] must call Vue.use(Vuex) before creating a store instance.
You need to add Vue.use(Vuex), also, you are not including your module in the main store
import { Store } from 'vuex'
import { Sources } from './sources'
Vue.use(Vuex)
export const store = new Store({
modules: {
Sources
}
})

I have a UserStore which contains some information about the current user. This store also is responsible for loggin in and out.
In order to make the getters available I map the getters to my computed attribute within my Vue component.
Unfortunately I get an error saying that it cannot access useUserStore before initilization.
This is my component:
<template>
//...
</template>
<script>
import {mapState} from "pinia"
import {useUserStore} from "../../stores/UserStore.js";
import LoginForm from "../../components/forms/LoginForm.vue";
export default {
name: "Login",
components: {LoginForm},
computed: {
...mapState(useUserStore, ["user", "isAuthenticated"]) //commenting this out makes it work
}
}
</script>
This is my store:
import { defineStore } from 'pinia'
import {gameApi} from "../plugins/gameApi.js"
import {router} from "../router.js";
export const useUserStore = defineStore("UserStore", {
persist: true,
state: () => ({
authenticated: false,
_user: null
}),
getters: {
user: (state) => state._user,
isAuthenticated: (state) => state.authenticated
},
actions: {
async checkLoginState() {
// ...
},
async loginUser(fields) {
// ...
},
async logutUser() {
// ...
}
}
})
And my main.js
import {createApp} from 'vue'
import App from './App.vue'
import gameApi from './plugins/gameApi'
import {router} from './router.js'
import store from "./stores/index.js";
createApp(App)
.use(store)
.use(router)
.use(gameApi)
.mount('#app')
And finally my store configuration:
import {createPinia} from "pinia"
import piniaPluginPersistedstate from 'pinia-plugin-persistedstate'
import {useUserStore} from "./UserStore.js";
const piniaStore = createPinia()
piniaStore.use(piniaPluginPersistedstate)
export default {
install: (app, options) => {
app.use(piniaStore)
const userStore = useUserStore()
const gameStore = useGameStore()
}
}
I wasn't able to initialize the store using the "old" way comparable with Vuex. Instead I had to make use of the setup() function Pinia Docu:
<script>
import {useUserStore} from "../../stores/UserStore.js";
export default {
name: "RegisterForm",
setup() {
// initialize the store
const userStore = useUserStore()
return {userStore}
},
data() {
return {
// ...
}
},
methods: {
checkLoginState() {
this.userStore.checkLoginState()
}
}
}
</script>
I have just started using Vue3, and am trying to use vuex to manage state. when using Vue2 I would call the store each time the app loads like this:
// mains.js
import VueRouter from "vue-router";
import Vuex from "vuex";
import router from "./routes";
window.Vue = require('vue').default;
Vue.use(VueRouter);
Vue.use(VueMoment);
Vue.use(Vuex);
const store = new Vuex.Store(storeDefinition);
const app = new Vue({
el: '#app',
router,
store,
components: {
"index": Index
},
async created() {
this.$store.dispatch("loadStoredState");
this.$store.dispatch("loadUser");
},
});
This is my vuex store that defines state, mutations and actions for vuex:
// store.js
import { isLoggedIn, logOut } from "./shared/utils/auth";
export default {
state: {
isLoggedIn: false,
user: {}
},
mutations: {
setUser(state, payload) {
state.user = payload;
},
setLoggedIn(state, payload) {
state.isLoggedIn = payload;
}
},
actions: {
loadStoredState(context) {
context.commit("setLoggedIn", isLoggedIn());
},
async loadUser({ commit, dispatch }) {
if (isLoggedIn()) {
try {
const user = (await axios.get("/user")).data;
commit("setUser", user);
commit("setLoggedIn", true);
} catch (error) {
dispatch("logout");
}
}
},
logout({ commit }) {
commit("setUser", {});
commit("setLoggedIn", false);
logOut();
}
},
getters: {}
}
This file manages a cookie for local storage that stores a boolean value for isLoggedIn:
// auth.js
export function isLoggedIn() {
return localStorage.getItem("isLoggedIn") == 'true';
}
export function logIn() {
localStorage.setItem("isLoggedIn", true);
}
export function logOut() {
localStorage.setItem("isLoggedIn", false);
}
But in Vue3 I am creating the main.js file like this:
// mains.js
const { createApp } = require('vue')
import Index from './Index.vue'
import createRouter from './router'
import { createStore } from 'vuex'
import storeDefinition from "./store";
const store = createStore(storeDefinition)
createApp(Index)
.use(createRouter())
.use(store)
.mount('#app')
How can I add the two calls to manage the store to the createApp function?
You can add the created hook to the root component by using the extends option with the component definition:
// main.js
import { createApp } from 'vue'
import Index from './Index.vue'
import createRouter from './router'
import { createStore } from 'vuex'
import storeDefinition from './store'
const store = createStore(storeDefinition)
createApp({
extends: Index,
created() {
this.$store.dispatch('loadStoredState')
this.$store.dispatch('loadUser')
},
})
.use(createRouter())
.use(store)
.mount('#app')
demo
I got a vuex store like this:
const state = {
status: '',
};
const getters = {
//...
};
const actions = {
// ...
};
const mutations = {
// ...
};
export default {
namespaced: true,
state,
getters,
actions,
mutations,
}
Now I'd like to access app.config.globalProperties.$notify
In Vue.js2 I was using something like Vue.prototype.$notify, but this is not working anymore.
$notify is also provided like this:
app.use(routes)
.provide('notify', app.config.globalProperties.$notify)
.mount('#app')
Unfortunately I did not find any information about this in the docs yet.
So my question: How can I either inject $notify or access app.config.globalProperties within this store?
From your store and its modules, you could return a store factory -- a function that receives the application instance from createApp and returns a store:
// store/modules/my-module.js
const createStore = app => {
const mutations = {
test (state, { committedItem }) {
app.config.globalProperties.$notify('commited item: ' + committedItem)
}
}
return {
namespaced: true,
//...
mutations,
}
}
export default app => createStore(app)
// store/index.js
import { createStore } from 'vuex'
import myModule from './modules/my-module'
export default app =>
createStore({
modules: {
myModule: myModule(app)
}
})
Then use the store factory like this:
// main.js
import { createApp } from 'vue'
import App from './App.vue'
import createStore from './store'
const app = createApp(App)
app.use(createStore(app)).mount('#app')

Hello developers I'm working with Ionic and Vue+Vuex in this app, but eventually, I can't access my state from my getters for some reason.
As usually the management state is settled for that purpose with actions getters, mutations, and state.
import { createStore } from "vuex";
const urlLogin = "http://localhost:3006/auth";
const urlUser = "http://localhost:3006/user";
const store = createStore({
state() {
return {
userRegisteredState: false,
allUsersState: [],
};
},
mutations: {
commit_get_all_users(state, payload) {
console.log(payload);
return (state.allUsersState = payload);
},
},
getters: {
getterGetAllUsers(state) {
console.log(state);//checking all state (See image )
console.log(state.allUsersState)//checking only the item I want to consume from state (See image )
return state.allUsersState;
},
},
actions: {
//=================================================================
//============================================================
async getAllUsers({ commit }) {
fetch(`${urlUser}/get/all/users`, {
method: "GET",
headers: {
"Content-Type": "application/json",
"Access-Control-Allow-Origin": "http://localhost:8100",
},
})
.then((result) => {
return result.json();
})
.then((result) => {
console.log(result);
commit("commit_get_all_users", result);
})
.catch((error) => {
console.log(error);
error;
});
},
},
});
export default store;
then on my component , in this case that one referring to get all users I set this logic:
<template>
...some tags...
</template>
<script>
import { mapActions, mapGetters } from "vuex";
export default {
name: "AllUsersComponent",
data() {
return {
allUsers: [],
};
},
methods: {
...mapActions(["getAllUsers"]),
getAllUsersFront() {
this.$store.dispatch("getAllUsers");
},
...some methods....
},
computed: {
...mapGetters(["getterGetAllUsers"]),
getterGetAllUsersFunction() {
console.log(this.$store.getters.getterGetAllUsers);
return this.$store.getters.getterGetAllUsers;
},
},
async mounted() {
this.getAllUsersFront();
},
created() {
this.getAllUsersFront();
this.getterGetAllUsersFunction;
console.log(this.getterGetAllUsersFunction);
},
watch: {},
};
</script>
<style>
</style>
On my main.js file store is imported according to IONC in this way
import { createApp } from "vue";
import './gapi.js'
import App from "./App.vue";
import router from "./router";
import store from "./store/index"; //importando vuex
import loginComponentTag from "./components/Login";
import allUsersComponentTag from "./components/all-users-component"
// import GoogleSignInButton from 'vue-google-signin-button-directive'
import { IonicVue } from "#ionic/vue";
/* Core CSS required for Ionic components to work properly */
import "#ionic/vue/css/core.css";
/* Basic CSS for apps built with Ionic */
import "#ionic/vue/css/normalize.css";
import "#ionic/vue/css/structure.css";
import "#ionic/vue/css/typography.css";
/* Optional CSS utils that can be commented out */
import "#ionic/vue/css/padding.css";
import "#ionic/vue/css/float-elements.css";
import "#ionic/vue/css/text-alignment.css";
import "#ionic/vue/css/text-transformation.css";
import "#ionic/vue/css/flex-utils.css";
import "#ionic/vue/css/display.css";
/* Theme variables */
import "./theme/variables.css";
const app = createApp(App)
.use(IonicVue)
.use(store)
.use(router)
app.component("LoginComponent", loginComponentTag);
app.component("AllUsersComponent",allUsersComponentTag)
router.isReady().then(() => {
app.mount("#app");
});
And my vue.config.js is settled in this way:
module.exports = {
devServer: {
proxy: "http://localhost:8100",
},
};
I checked my logs and eventually.
Literally, the situation is that despite having my state populated with data, unless I retrieve the whole state, I can't retrieve a particular item from it, cause the response is nothing.
Is there any configuration I'm omitting in this process I need to have in mind?
