Veujs Vuex store management working

Veujs Vuex store management working

Vue.js and Vuex work together to manage state in Vue applications in a centralized and organized way, especially useful in complex applications. Vuex is a state management pattern and library for Vue.js applications, providing a centralized store for all the components in an application. Here’s a basic overview of how Vuex store management works:

  1. State: The state is the central data repository that Vuex manages. It’s a single source of truth for your application’s data, accessible by all components.
  2. Mutations: Mutations are synchronous functions that change the state. They are the only way to modify state in Vuex, ensuring that state changes are predictable and trackable. Mutations are committed, not called directly, signaling Vuex to perform the actual state update.
  3. Actions: Actions are similar to mutations, but they are meant to handle asynchronous operations before committing mutations. An action can commit one or several mutations. Actions are dispatched, not called directly, allowing them to perform any asynchronous operation before committing to a mutation.
  4. Getters: Getters are to Vuex what computed properties are to Vue components. They compute derived state based on the store’s state and can be used to perform operations like filtering a list or counting items before passing data to components.
  5. Modules: For large applications, the store can be divided into modules. Each module can contain its own state, mutations, actions, getters, and even nested modules. This helps keep the store organized and manageable.

Basic Example

Here’s a simple Vuex store example:

import Vue from 'vue';
import Vuex from 'vuex';


const store = new Vuex.Store({
  state: {
    count: 0
  mutations: {
    increment(state) {
  actions: {
    increment({ commit }) {
  getters: {
    doubleCount(state) {
      return state.count * 2;

export default store;

In this example:

  • The state contains a single count property.
  • A mutation is defined to increment the count.
  • An action named increment is created to commit the increment mutation.
  • A getter named doubleCount returns the count multiplied by two.

Using Vuex in Components

To use Vuex state and perform actions from a Vue component:

  <div>{{ doubleCount }}</div>
  <button @click="increment">Increment</button>

import { mapGetters, mapActions } from 'vuex';

export default {
  computed: {
      'doubleCount' // maps this.doubleCount to this.$store.getters.doubleCount
  methods: {
      'increment' // maps this.increment() to this.$store.dispatch('increment')

In this component, mapGetters is used to map store getters to local computed properties, and mapActions is used to map store actions to local methods. This allows the component to display the doubleCount value from the store and dispatch an action to increment the count when a button is clicked.
