Navigating through different views in a Vue application using Vue Router directly from Vuex actions

Question

Navigating through different views in a Vue application using Vue Router directly from Vuex actions

Currently, I am in the process of developing a web application using Vue 2.x and Vuex 2.x. In this project, I need to retrieve some data from an external source via an http call. If this call fails, my objective is to redirect to a different page.

GET_PETS: (state) => {
  return $http.get('pets/').then((response)=>{
      state.commit('SET_PETS', response.data)
    })
  },
  error => {this.$router.push({path:"/"}) }
  )
}

However, when attempting this.$router.push({path:"/"}), an error is thrown as follows:

Uncaught (in promise) TypeError: Cannot read property 'push' of undefined

I am seeking advice on how to accomplish this task effectively.

For a simulated example, check out this JsFiddle: here

Answer №1

If you have your router instance exported in a file within your app (for example, ./router.js), you can easily import it and use it anywhere you need - even in Vuex stores:

import router from './router';

Once imported, you can simply call router.push().

It's as straightforward as that.

This demonstration could be beneficial.

main.js

import Vue from "vue";
import VueRouter from "vue-router";

...

Vue.use(VueRouter);

export const routing = new VueRouter({
    mode: 'hash',
    base: "./",
    routes: [
        { path: "/", component: welcome},
        { path: "/welcome", component: welcome},

    ]
})

actions.js

import {routing} from "../main.js"

export const performAction = ({commit}) => {

    routing.push("/welcome");
}

STARTING POINT

Within the file main.js (the one where all modules are installed and a Vue instance is created, like in src/main.js):

const vm = new Vue({
  el: '#app',
  router,
  store,
  apolloProvider,
  components: { App },
  template: '<App/>'
})

export { vm }

This serves as an example, with focus on const vm and router in our context.

In your store:

import { vm } from '@/main'

yourMutation (state, someRouteName) {
  vm.$router.push({name: someRouteName})
}

P.S. By using import { vm } from '@/main', we gain access to necessary elements in Vuex like vm.$root required by certain components of bootstrap-vue.

P.P.S. It's important to note that we can utilize vm only when everything is fully loaded. In simpler terms, cannot use vm inside someMutation if called within mounted() because mounted() occurs prior to the creation of vm.

FRESH PERSPECTIVE

Constantin's response (the accepted one) as explained here is more effective than mine, aimed at guiding beginners on its implementation.

Within the core directory (located in /src for me), alongside files like App.vue and main.js, I have a file named router.js structured as follows:

import Vue from 'vue'
import Router from 'vue-router'

// Traditional loading
import Home from '@/components/pages/Home/TheHome'

// Lazy loading (loaded when corresponding route is accessed)
const Page404 = () => import(/* webpackChunkName: "Page404" */ '@/components/pages/404)
const Page503 = () => import(/* webpackChunkName: "Page503" */ '@/components/pages/503)

Vue.use(Router)

const router = new Router({
  mode: 'hash',
  base: process.env.BASE_URL,
  linkExactActiveClass: 'active',
  routes: [
    {
      path: '*',
      name: 'Page404',
      component: Page404
    },

    {
      path: '*',
      name: 'Page503',
      component: Page503
    },

    {
      path: '/',
      name: 'Home',
      component: Home
    },

    // Additional routes
    {....},
    {....}
  ]
})

// Universal section allowing actions before entering a new route.
router.beforeEach(async (to, from, next) => {
  next()
})

export default router

Include our router in main.js:

import Vue from 'vue'
import App from './App.vue'
import router from './router'

Vue.config.productionTip = false

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

export { vm }

Lastly, be it within a component, Vuex, or any other place, remember to import router from './router' and proceed accordingly, such as invoking router.push(...)

It appears that the router is not properly integrated into your app, leading to it being undefined.

In older versions of vue-router, you would need to use Vue.use(VueRouter). However, with version 2.0, you can inject the router into the app in the following way:

const routes = [
  { path: '/foo', component: Foo },
]

const router = new VueRouter({
  routes
})

const app = new Vue({
  router // inject the router
}).$mount('#app')

This should allow you to access the router throughout the entire app using this.$router

After addressing a similar question on Stack Overflow: How to use Vue Router from Vuex state?, it became evident that Vuex does not automatically receive the router instance at this.$router. As a solution, two methods were proposed to gain access to the router instance.

The first method is more straightforward and involves setting a webpack global variable to the instance.

The second method suggests using Promises within your Vuex actions, allowing components to access the router instance after the Promise is resolved or rejected.

Answer №5

I found it cumbersome to maintain my app's location state separately from the main app state in the Store, along with managing both a Router and a Store simultaneously. To simplify this process, I decided to develop a Vuex module that handles the location state within the Store itself.

With this setup, I am now able to navigate through dispatching actions, just like any other state change:

dispatch("router/push", {path: "/error"})

This approach also streamlines tasks like managing animated page transitions.

To import the route from the router directory, you can use the following code snippet:

import router from '@/router'

router.push({name: 'Home'})

The @ symbol serves as a shortcut for referencing the path to the src directory.
