I'm trying to redirect to dashboard after login.
I found this in app.js file that
// make router instance available in store store.$router = router
So I codede that in my login method of auth.js file like below.
store.$router.push({ name: 'dashboard' })
But there is nothing to happen.
How can I use router in vuex store file?
Router is not available in the store directly. You might have to use plugin which makes the router available to the store.
Here is the Vuex-Router plugin which helps to access router to the store.
Are you trying to call router.push in an vuex action?
If so i am doing the same in my quasar v2 project
store/auth/actions.js
import { api } from 'boot/axios'
export function login({ dispatch, commit }, data) {
return api.post('/user/login', data).then(res => {
commit('setToken', res.data.token)
this.$router.push({ name: 'dashboard' }) // <-- What you are looking for?
}).catch(err => {
let msg = err.response.data || 'Error occurred'
return Promise.reject(msg)
})
}

My script I'm using axios and vuex but it was necessary to make a change from formData to Json in the script and with that it's returning from the POST/loginB2B 200 api, but it doesn't insert in the localstorage so it doesn't direct to the dashboard page.
**Auth.js**
import axios from "axios";
const state = {
user: null,
};
const getters = {
isAuthenticated: (state) => !!state.user,
StateUser: (state) => state.user,
};
async LogIn({commit}, user) {
await axios.post("loginB2B", user);
await commit("setUser", user.get("email"));
},
async LogOut({ commit }) {
let user = null;
commit("logout", user);
},
};
**Login.vue**
methods: {
...mapActions(["LogIn"]),
async submit() {
/*const User = new FormData();
User.append("email", this.form.username)
User.append("password", this.form.password)*/
try {
await this.LogIn({
"email": this.form.username,
"password": this.form.password
})
this.$router.push("/dashboard")
this.showError = false
} catch (error) {
this.showError = true
}
},
},
app.vue
name: "App",
created() {
const currentPath = this.$router.history.current.path;
if (window.localStorage.getItem("authenticated") === "false") {
this.$router.push("/login");
}
if (currentPath === "/") {
this.$router.push("/dashboard");
}
},
};
The api /loginB2B returns 200 but it doesn't create the storage to redirect to the dashboard.
I use this example, but I need to pass json instead of formData:
https://www.smashingmagazine.com/2020/10/authentication-in-vue-js/
There are a couple of problems here:
You do a window.localStorage.getItem call, but you never do a window.localStorage.setItem call anywhere that we can see, so that item is probably always empty. There also does not seem to be a good reason to use localStorage here, because you can just access your vuex store. I noticed in the link you provided that they use the vuex-persistedstate package. This does store stuff in localStorage by default under the vuex key, but you should not manually query that.
You are using the created lifecycle hook in App.vue, which usually is the main component that is mounted when you start the application. This also means that the code in this lifecycle hook is executed before you log in, or really do anything in the application. Instead use Route Navigation Guards from vue-router (https://router.vuejs.org/guide/advanced/navigation-guards.html).
Unrelated, but you are not checking the response from your axios post call, which means you are relying on this call always returning a status code that is not between 200 and 299, and that nothing and no-one will ever change the range of status codes that result in an error and which codes result in a response. It's not uncommon to widen the range of "successful" status codes and perform their own global code based on that. It's also not uncommon for these kind of endpoints to return a 200 OK status code with a response body that indicates that no login took place, to make it easier on the frontend to display something useful to the user. That may result in people logging in with invalid credentials.
Unrelated, but vuex mutations are always synchronous. You never should await them.
There's no easy way to solve your problem, so I would suggest making it robust from the get-go.
To properly solve your issue I would suggest using a global navigation guard in router.js, mark with the meta key which routes require authentication and which do not, and let the global navigation guard decide if it lets you load a new route or not. It looks like the article you linked goes a similar route. For completeness sake I will post it here as well for anyone visiting.
First of all, modify your router file under router/index.js to contain meta information about the routes you include. Load the store by importing it from the file where you define your store. We will then use the Global Navigation Guard beforeEach to check if the user may continue to that route.
We define the requiresAuth meta key for each route to check if we need to redirect someone if they are not logged in.
router/index.js
import Vue from 'vue';
import VueRouter from 'vue-router';
import store from '../store';
Vue.use(VueRouter);
const routes = [
{
path: '/',
name: 'Dashboard',
component: Dashboard,
meta: {
requiresAuth: true
}
},
{
path: '/login',
name: 'Login',
component: Login,
meta: {
requiresAuth: false
}
}
];
// Create a router with the routes we just defined
const router = new VueRouter({
mode: 'history',
base: process.env.BASE_URL,
routes
})
// This navigation guard is called everytime you go to a new route,
// including the first route you try to load
router.beforeEach((to, from, next) => {
// to is the route object that we want to go to
const requiresAuthentication = to.meta.requiresAuth;
// Figure out if we are logged in
const userIsLoggedIn = store.getters['isAuthenticated']; // (maybe auth/isAuthenticated if you are using modules)
if (
(!requiresAuthentication) ||
(requiresAuthentication && userIsLoggedIn)
) {
// We meet the requirements to go to our intended destination, so we call
// the function next without any arguments to go where we intended to go
next();
// Then we return so we do not run any other code
return;
}
// Oh dear, we did try to access a route while we did not have the required
// permissions. Let's redirect the user to the login page by calling next
// with an object like you would do with `this.$router.push(..)`.
next({ name: 'Login' });
});
export default router;
Now you can remove the created hook from App.vue. Now when you manually change the url in the address bar, or use this.$router.push(..) or this.$router.replace(..) it will check this function, and redirect you to the login page if you are not allowed to access it.
I've created a Nuxt plugin that is loaded in the config file with some global functions. In one function, I'd like to access the router, and push to a new route. I am getting an error that router is undefined. Can someone help me understand how I access the router here, if its not attached to the context.
export default (context, inject) => {
const someFunction = () => {
context.router.push({ name: 'route-name' } })
}
}
Try to destruct the context then use app to access the router :
export default ({app}, inject) => {
const someFunction = () => {
app.router.push({ name: 'route-name' } })
}
}
I figured this out. When using context, you can access the router, like this:
context.app.router
I'm using storyblok-nuxt module. I plugged it in nuxt.cofig.js and it works fine in page when I call it directly in the asyncData method as such:
asyncData({ app }) {
return app.$storyapi.get("cdn/stories/articles", {
version: "draft"
})
In order to call it from vuex I'm importing it:
import storyapi from 'storyapi'
But Nuxt gives me an error:
Cannot find module 'storyapi'
Can I use this module in vuex, and if yes - what's solution?
Using storyapi with Nuxt is very easy. In your asyncData you can dispatch your action like:
asyncData ({ store }) {
store.dispatch('loadSettings', {version: "draft"})
}
And in your store actions, you can go for this.$storyapi directly. There is no need to import anything. Nuxt take cares of everything for you:
export const actions = {
loadSettings({commit}, context) {
return this.$storyapi.get("cdn/stories/articles", {
version: context.version
}).then((res) => {
// execute your action and set data
commit('setSettings', res.data)
})
}
}

In my component , I have a method which will execute a router.push()
import router from "#/router";
// ...
export default {
// ...
methods: {
closeAlert: function() {
if (this.msgTypeContactForm == "success") {
router.push("/home");
} else {
return;
}
},
// ....
}
}
I want to test it...
I wrote the following specs..
it("should ... go to home page", async () => {
// given
const $route = {
name: "home"
},
options = {
...
mocks: {
$route
}
};
wrapper = mount(ContactForm, options);
const closeBtn = wrapper.find(".v-alert__dismissible");
closeBtn.trigger("click");
await wrapper.vm.$nextTick();
expect(alert.attributes().style).toBe("display: none;")
// router path '/home' to be called ?
});
1 - I get an error
console.error node_modules/#vue/test-utils/dist/vue-test-utils.js:15
[vue-test-utils]: could not overwrite property $route, this is usually caused by a plugin that has added the property asa read-only value
2 - How I should write the expect() to be sure that this /home route has been called
thanks for feedback
You are doing something that happens to work, but I believe is wrong, and also is causing you problems to test the router. You're importing the router in your component:
import router from "#/router";
Then calling its push right away:
router.push("/home");
I don't know how exactly you're installing the router, but usually you do something like:
new Vue({
router,
store,
i18n,
}).$mount('#app');
To install Vue plugins. I bet you're already doing this (in fact, is this mechanism that expose $route to your component). In the example, a vuex store and a reference to vue-i18n are also being installed.
This will expose a $router member in all your components. Instead of importing the router and calling its push directly, you could call it from this as $router:
this.$router.push("/home");
Now, thise makes testing easier, because you can pass a fake router to your component, when testing, via the mocks property, just as you're doing with $route already:
const push = jest.fn();
const $router = {
push: jest.fn(),
}
...
mocks: {
$route,
$router,
}
And then, in your test, you assert against push having been called:
expect(push).toHaveBeenCalledWith('/the-desired-path');
Assuming that you have setup the pre-requisities correctly and similar to this
Just use
it("should ... go to home page", async () => {
const $route = {
name: "home"
}
...
// router path '/home' to be called ?
expect(wrapper.vm.$route.name).toBe($route.name)
});
I have an application in nuxt that I want to connect to a websocket, I have seen examples where the callback to receive messages is placed inside a component, but I do not think ideal, I would like to place the callback inside my store, currently my code is something like this
//I'm using phoenix websocket
var ROOT_SOCKET = `wss://${URL}/socket`;
var socket = new Socket(ROOT_SOCKET);
socket.connect()
var chan = socket.channel(`connect:${guid}`);
chan.join();
console.log("esperando mensj");
chan.on("translate", payload => {
console.log(JSON.stringify(payload));
<store>.commit("loadTranslation",payload) //<- how can I access to my store?
})
chan.onError(err => console.log(`ERROR connecting!!! ${err}`));
const createStore = () => {
return new Vuex.Store({
state: {},
mutations:{
loadTranslation(state,payload){...}
},
....
})}
how can I access to my store inside my own store file and make a commit??? is it possible?...
I know there is a vuex plugin but I can't really understand well the documentation and I'll prefer build this without that plugin
https://vuex.vuejs.org/guide/plugins.html
thank you guys...hope you can help me...
You can do it in nuxt plugin https://nuxtjs.org/guide/plugins/
export default {
plugins: ['~/plugins/chat.js']
}
// chat.js
export default ({ store }) => {
your code that use store here
}
