How do I integrate Vuex with Vue Router in a Vue.js application?

To integrate Vuex with Vue Router, you can use Vuex to manage your application's state and Vue Router to handle navigation. First, ensure you have both Vuex and Vue Router installed in your Vue.js project.

What are the steps to set up Vuex and Vue Router?

1. Install Vuex and Vue Router using npm. 2. Create a Vuex store and define your state, mutations, and actions. 3. Set up Vue Router with your routes. 4. In your main.js file, import the store and router, then create your Vue instance with both.

Can you show me a code example?

Sure! Here's a basic example:

import Vue from 'vue';
import Vuex from 'vuex';
import VueRouter from 'vue-router';

Vue.use(Vuex);
Vue.use(VueRouter);

const store = new Vuex.Store({
  state: { count: 0 },
  mutations: { increment(state) { state.count++; } }
});

const router = new VueRouter({
  routes: [
    { path: '/', component: Home },
    { path: '/about', component: About }
  ]
});

new Vue({
  store,
  router,
  render: h => h(App)
}).$mount('#app');

This sets up a basic Vue.js application with Vuex and Vue Router.

What are some common pitfalls when integrating them?

Common pitfalls include not properly managing state changes during navigation, forgetting to use Vuex actions for asynchronous operations, and not keeping your components reactive to state changes.
