How to solve Avoided redundant navigation to current location error in vue?
I am new in vue and i got the error after user logged in and redirect to another route. Basically i am a PHP developer and i use laravel with vue. Please help me to solve this error.
Uncaught (in promise) Error: Avoided redundant navigation to current location: "/admin".
Here is the screenshot too
Vue Code
methods: {
loginUser() {
var data = {
email: this.userData.email,
password: this.userData.password
};
this.app.req.post("api/auth/authenticate", data).then(res => {
const token = res.data.token;
sessionStorage.setItem("chatbot_token", token);
this.$router.push("/admin");
});
}
}
Vue Routes
const routes = [
{
path: "/admin",
component: Navbar,
name: "navbar",
meta: {
authGuard: true
},
children: [
{
path: "",
component: Dashboard,
name: "dashboard"
},
{
path: "users",
component: Users,
name: "user"
}
]
},
{
path: "/login",
component: Login,
name: "login"
}
];
const router = new VueRouter({
routes,
mode: "history"
});
router.beforeEach((to, from, next) => {
const loggedInUserDetail = !!sessionStorage.getItem("chatbot_token");
if (to.matched.some(m => m.meta.authGuard) && !loggedInUserDetail)
next({ name: "login" });
else next();
});
Solution 1:
As I remember well, you can use catch clause after this.$router.push. Then it will look like:
this.$router.push("/admin").catch(()=>{});
This allows you to only avoid the error displaying, because browser thinks the exception was handled.
Solution 2:
I don't think suppressing all errors from router is good practice, I made just picks of certain errors, like this:
router.push(route).catch(err => {
// Ignore the vuex err regarding navigating to the page they are already on.
if (
err.name !== 'NavigationDuplicated' &&
!err.message.includes('Avoided redundant navigation to current location')
) {
// But print any other errors to the console
logError(err);
}
});
Solution 3:
Maybe this is happening because your are trying to route to the existing $route.matched.path.
For original-poster
You may want to prevent the error by preventing a route to the same path:
if (this.$route.path != '/admin') {
this.$router.push("/admin");
}
Generic solutions
You could create a method to check for this if you are sending dynamic routes, using one of several options
- Easy: Ignore the error
-
Hard: Compare the
$route.matchedagainst the desired route
1. Ignore the error
You can catch the NavigationDuplicated exception and ignore it.
pushRouteTo(route) {
try {
this.$router.push(route);
} catch (error) {
if (!(error instanceof NavigationDuplicated)) {
throw error;
}
}
}
Although this is much simpler, it bothers me because it generates an exception.
2. Compare the $route.matched against the desired route
You can compare the $route.matched against the desired route
pushRouteTo(route) {
// if sending path:
if (typeof(route) == "string") {
if (this.$route.path != route) {
this.$router.push(route);
}
} else { // if sending a {name: '', ...}
if (this.$route.name == route.name) {
if ('params' in route) {
let routesMatched = true;
for (key in this.$route.params) {
const value = this.$route.params[key];
if (value == null || value == undefined) {
if (key in route.params) {
if (route.params[key] != undefined && route.params[key] != null) {
routesMatched = false;
break;
}
}
} else {
if (key in route.params) {
if (routes.params[key] != value) {
routesMatched = false;
break
}
} else {
routesMatched = false;
break
}
}
if (!routesMatched) {
this.$router.push(route);
}
}
} else {
if (Object.keys(this.$route.params).length != 0) {
this.$router.push(route);
}
}
}
}
}
This is obviously a lot longer but doesn't throw an error. Choose your poison.
Runnable demo
You can try both implementations in this demo:
const App = {
methods: {
goToPageCatchException(route) {
try {
this.$router.push(route)
} catch (error) {
if (!(error instanceof NavigationDuplicated)) {
throw error;
}
}
},
goToPageMatch(route) {
if (typeof(route) == "string") {
if (this.$route.path != route) {
this.$router.push(route);
}
} else { // if sending a {name: '', ...}
if (this.$route.name == route.name) {
if ('params' in route) {
let routesMatched = true;
for (key in this.$route.params) {
const value = this.$route.params[key];
if (value == null || value == undefined) {
if (key in route.params) {
if (route.params[key] != undefined && route.params[key] != null) {
routesMatched = false;
break;
}
}
} else {
if (key in route.params) {
if (routes.params[key] != value) {
routesMatched = false;
break
}
} else {
routesMatched = false;
break
}
}
if (!routesMatched) {
this.$router.push(route);
}
}
} else {
if (Object.keys(this.$route.params).length != 0) {
this.$router.push(route);
}
}
} else {
this.$router.push(route);
}
}
},
},
