Using Nuxt 3 and vue-gtag, what is the right way to access $gtag from components?
plugins/gtag.client.js:
import VueGtag from 'vue-gtag';
export default defineNuxtPlugin(nuxtApp => {
const router = useRouter();
nuxtApp.vueApp.use(
VueGtag,
{
config: {
id: '...'
}
},
router
);
});
In Nuxt 2, this.$gtag was accessible from component file.
In Nuxt 3, I can't seem to find it:
const nuxtApp = useNuxtApp();
nuxtApp.$gtag //undefined
Looking at the source code, it seems to be defined correctly, so I don't think it's a problem with the plugin itself.
app.config.globalProperties.$gtag = api;
I have same issue when define the domToImage plugin in nuxt 3. I found a solution as follow. Hope to help you.
Return provide in nuxt plugin:
import domtoimage from "dom-to-image-more";
export default defineNuxtPlugin((nuxtApp) => {
// nuxtApp.vueApp.use(domtoimage)
return {
provide: {
domtoimage
}
}
})
Use in component:
const print = () => {
console.log("Print ...")
const { $domtoimage } = useNuxtApp()
$domtoimage.toPng(printMeDiv)
.then((dataUrl) => {
console.log(dataUrl)
})
}
}
I am new to Vue and followed the recommendation to use vue testing library. The only issue is I can't seem to find a way to inject my code into globalProperties in render function.
Does anyone know of an example where I can inject or mock it out?
main.js
app.config.globalProperties.$globals = globalMethods
...
const app = createApp(App)
app.config.globalProperties.$globals = globalMethods
app.config.globalProperties.$globalVars = globalVars
app.component("font-awesome-icon", fontawesome)
app.use(applicationStore);
app.use (Hotjar, hotjarConfig)
app.use(i18n)
app.use(router)
app.mount('#app')
From my vue component in create I am able to call
Component.vue
let formatedObj = this.$globals.maskValues(this.inputValue, this.inputType, this);
...
,
created() {
let formatedObj = this.$globals.maskValues(this.inputValue, this.inputType, this);
this.myInputValue = formatedObj.formatedString;
this.formatedCharacterCount = formatedObj.formatedCharacterCount;
this.prevValue = this.myInputValue;
},
...
tesst.spec.js
import { render } from '#testing-library/vue'
import FormatedNumericInput from '#/components/Component.vue'
import {globalMethods} from'#/config/global-methods'
const label = 'Price'
const initSettings = {
props: {
inputId: 'testInputId1',
labelTxt: label
}
};
beforeEach(() => {
});
test('a simple string that defines your test', () => {
const { getByLabelText } = render(FormatedNumericInput, initSettings)
const input = getByLabelText(label)
// testing logic
expect(input != null).toBe(true)
expect(FormatedNumericInput != null).toBe(true)
})
** ERROR **
TypeError: Cannot read property 'maskValues' of undefined
85 | },
86 | created() {

at Proxy.created (src/components/FormatedNumericInput.vue:87:37)
The second argument of render() is passed to #vue/test-utils mount(), so you could include the global.mocks mounting option to mock $globals.maskValues:
const { getByLabelText } = render(FormatedNumericInput, {
...initSettings,
global: {
mocks: {
$globals: {
maskValues: (inputValue, inputType) => {
const formatedString = globalFormatValue(inputValue) // declared elsewhere
return {
formatedString,
formatedCharacterCount: formatedString.length,
}
}
}
}
}
})
This is my solution in actual Vue3/Vite/Vitest environment, I set some mocks globally, so I don't need to in every test suite.
// vitest.config.ts
import { mergeConfig } from 'vite';
import { defineConfig } from 'vitest/config';
import viteConfig from './vite.config';
export default defineConfig(
mergeConfig(viteConfig, { // extending app vite config
test: {
setupFiles: ['tests/unit.setup.ts'],
environment: 'jsdom',
}
})
);
// tests/unit.setup.ts
import { config } from "#vue/test-utils"
config.global.mocks = {
$t: tKey => tKey; // just return translation key
};
so for you it will be something like
config.global.mocks = {
$globals: {
maskValues: (inputValue, inputType) => {
// ...implementation
return {
formatedString,
formatedCharacterCount,
}
}
}
}
I work with Vue3 in TS (last vue-cli).
I want to get all nodes (vnodes) elements when vue-loader compile .vue file.
I need to read nodes attributes and remove all "data-test".
I have try in vue.config.js to use :
module.exports = {
chainWebpack: (config) => {
config.module
.rule('vue')
.use('vue-loader')
// .loader('vue-loader') // same with
.tap((options) => {
options.compilerOptions = {
...(options.compilerOptions || {}),
modules: [ // never enter here
{
preTransformNode(node) {
// if (process.env.NODE_ENV === 'production') {
const { attrsMap, attrsList } = node
console.log(node)
if (attrsMap['qa-id']) {
delete attrsMap['qa-id']
const index = attrsList.findIndex(
(x) => x.name === 'data-test'
)
attrsList.splice(index, 1)
}
// }
return node
}
}
]
}
return options
})
}
}
I know the transformation is done inside vue-template-compiler.
How can I enter in compile hook ?
I have try to use preTransformNode in module but that fail.
Sources :
https://github.com/vuejs/vue/tree/dev/packages/vue-template-compiler#readme
https://vue-loader.vuejs.org/options.html
The main problem here is that you are working with vue-template-compiler documentation, but that package is the compiler for Vue 2!
In Vue 3, compiler is split into multiple packages and is missing proper documentation as of now (or I was just unable to find it)
Also there were significant changes in the API - instead of modules, you pass nodeTransforms (source) and transforms are not objects, just functions.
Luckily for you, there is a interesting video on YT presented by Vue core member Rahul Kadyan which shows the exact use case you need (removing data-test attributes) - code
So I guess the code should look like this:
function removeDataTestAttrs(node) {
if (node.type === 1 /* NodeTypes.ELEMENT */) {
node.props = node.props.filter(prop =>
prop.type === 6 /* NodeTypes.ATTRIBUTE */
? prop.name !== 'data-test'
: true
)
}
}
module.exports = {
parallel: false, // !!IMPORTANT!! - see note below
chainWebpack: (config) => {
config.module
.rule('vue')
.use('vue-loader')
.tap((options) => {
options.compilerOptions = {
...(options.compilerOptions || {}),
nodeTransforms: [removeDataTestAttrs]
}
return options
})
}
}
Note - the problem mentioned in comments (solution working with serve but throws errors on build) is caused by Vue CLI using thread-loader for production builds. The problem is that while using thread-loader, you can not pass a functions as part of Webpack config (see this warning in the docs) so setting parralel: false is required to make it work....

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.$router.push("/admin");
});
}
}
Vue Routes
const routes = [
{
path: "/admin",
component: Navbar,
name: "navbar",
meta: {
authGuard: true
},
children: [
{
path: "",
component: Dashboard,
name: "dashboard"
},
{
path: "users",
component: Users,
name: "user"
}
]
},
{
path: "/login",
component: Login,
name: "login"
}
];
const router = new VueRouter({
routes,
mode: "history"
});
router.beforeEach((to, from, next) => {
const loggedInUserDetail = !!sessionStorage.getItem("chatbot_token");
if (to.matched.some(m => m.meta.authGuard) && !loggedInUserDetail)
next({ name: "login" });
else next();
});
As I remember well, you can use catch clause after this.$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.
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);
}
});
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 $route.matched against the desired route
1. Ignore the error
You can catch the NavigationDuplicated exception and ignore it.
pushRouteTo(route) {
try {
this.$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);
}
}
},
},

Just to make this complete you can also compare the from and to route fullPaths and compare them against each other which seems to me a simple, valid and reusable solution.
Here is an example in a component method:
move(params){
// get comparable fullPaths
let from = this.$route.fullPath
let to = this.$router.resolve(params).route.fullPath
if(from === to) {
// handle any error due the redundant navigation here
// or handle any other param modification and route afterwards
return
}
// route as expected
this.$router.push(params)
}
If you wanna use that you just put your route params in it like this.move({ name: 'something' }). This is the easiest way to handle the duplicate route without running into try catch syntax. And also you can have that method exported in Vue.prorotype.$move = ... which will work across the whole application.
I found the solution by adding the following code to router.js:
import router from 'vue-router';
const originalPush = router.prototype.push
router.prototype.push = function push(location) {
return originalPush.call(this, location).catch(err => err)
}
Provide a Typescript solution
The idea is to overwrite the router.push function. You can handle (ignore) the error in one place, instead of writing catch everywhere to handle it.
This is the function to overwrite
export declare class VueRouter {
// ...
push(
location: RawLocation,
onComplete?: Function,
onAbort?: ErrorHandler
): void
}
Here is the code
// in router/index.ts
import Vue from 'vue';
import VueRouter, { RawLocation, Route } from 'vue-router';
Vue.use(VueRouter);
const originalPush = VueRouter.prototype.push;
VueRouter.prototype.push = function push(location: RawLocation): Promise<Route> {
return new Promise((resolve, reject) => {
originalPush.call(this, location, () => {
// on complete
resolve(this.currentRoute);
}, (error) => {
// on abort
// only ignore NavigationDuplicated error
if (error.name === 'NavigationDuplicated') {
resolve(this.currentRoute);
} else {
reject(error);
}
});
});
};
// your router configs ...
you can define and use a function like this:
routerPush(path) {
if (this.$route.path !== path) {
this.$router.push(path);
}
}
It means - you want to navigate to a route that looks the same as the current one and Vue doesn’t want to trigger everything again.
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);
// Here you conditioally navigate to admin page to prevent error raised
if(this.$route.name !== "/admin") {
this.$router.push("/admin");
}
});
}
}
Clean solution ;)
Move the code to an util function. So you can replace all this.$router.push with it.
import router from '../router'; // path to the file where you defined
// your router
const goToRoute = (path) =>
if(router.currentRoute.fullPath !== path) router.push(path);
export {
goToRoute
}
In addition to the above mentioned solutions: a convenient way is to put this snippet in main.js to make it a global function
Vue.mixin({
/**
* Avoids redundand error when navigating to already active page
*/
routerPush(route) {
this.$router.push(route).catch((error) => {
if(error.name != "NavigationDuplicated") {
throw error;
}
})
},
})
Now you can call in any component:
this.routerPush('/myRoute')
Global solution
In router/index.js, after initialization
// init or import router..
/* ... your routes ... */
// error handler
const onError = (e) => {
// avoid NavigationDuplicated
if (e.name !== 'NavigationDuplicated') throw e
}
// keep original function
const _push = router.__proto__.push
// then override it
router.__proto__.push = function push (...args) {
try {
const op = _push.call(this, ...args)
if (op instanceof Promise) op.catch(onError)
return op
} catch (e) {
onError(e)
}
}
I have added the code below in the main.js file of my project and the error disappeared.
import Router from 'vue-router'
const routerPush = Router.prototype.push
Router.prototype.push = function push(location) {
return routerPush.call(this, location).catch(error => error)
};
I have experienced the same issue and when I looked for a solution I found .catch(() => {}) which is actually telling the browser that we have handled the error please don’t print the error in dev tools :) Hehehe Nice hack! but ignoring an error is not a solution I think. So what I did, I created a utility function that takes two parameters router, path, and compares it with the current route's path if both are the same it means we already on that route and it ignore the route change. So simple :)
Here is the code.
export function checkCurrentRouteAndRedirect(router, path) {
const {
currentRoute: { path: curPath }
} = router;
if (curPath !== path) router.push({ path });
}
checkCurrentRouteAndRedirect(this.$router, "/dashboard-1");
checkCurrentRouteAndRedirect(this.$router, "/dashboard-2");
I had this problem and i solve it like that.
by adding that in my router file
import Router from 'vue-router'
Vue.use(Router)
const originalPush = Router.prototype.push
Router.prototype.push = function push(location) {
return originalPush.call(this, location).catch(err => err)
}
Short solution:
if (this.$router.currentRoute.name !== 'routeName1') {
this.$router.push({
name: 'routeName2',
})
}
Late to the party, but trying to add my 10 cents. Most of the answers- including the one which is accepted are trying to hide the exception without finding the root cause which causes the error. I did have the same issue in our project and had a feeling it's something to do with Vue/ Vue router. In the end I managed to prove myself wrong and it was due to a code segment we had in App.vue to replace the route in addition to the similar logic like you in the index.ts.
this.$router.replace({ name: 'Login' })
So try to do a search and find if you are having any code which calls $router.replace OR $router.push for the route you are worried about- "/admin". Simply your code must be calling the route more than once, not the Vue magically trying to call it more than once.
I guess this answer comes in super late. Instead of catching the error I looked for a way to prevent the error the come up. Therefore I've enhanced the router by an additional function called pushSave. Probably this can be done via navGuards as well
VueRouter.prototype.pushSave = function(routeObject) {
let isSameRoute = true
if (this.currentRoute.name === routeObject.name && routeObject.params) {
for (const key in routeObject.params) {
if (
!this.currentRoute.params[key] ||
this.currentRoute.params[key] !== routeObject.params[key]
) {
isSameRoute = false
}
}
} else {
isSameRoute = false
}
if (!isSameRoute) {
this.push(routeObject)
}
}
const router = new VueRouter({
routes
})
As you've probably realized this will only work if you provide a routeObject like
this.$router.pushSave({ name: 'MyRoute', params: { id: 1 } })
So you might need to enhance it to work for strings aswell
For components <router-link>
You can create a new component instead of <router-link>.
Component name: <to-link>
<template>
<router-link :to="to" :event="to === $route.path || loading ? '' : 'click'" :class="classNames">
<slot></slot>
</router-link>
</template>
<script>
export default {
name: 'ToLink',
props: {
to: {
type: [String, Number],
default: ''
},
classNames: {
type: String,
default: ''
},
loading: {
type: Boolean,
default: false
}
}
}
</script>
For bind:
import ToLink from '#/components/to-link'
Vue.component('to-link', ToLink)
For $router.push() need create global method.
toHttpParams(obj) {
let str = ''
for (const key in obj) {
if (str !== '') {
str += '&'
}
str += key + '=' + encodeURIComponent(obj[key])
}
return str
},
async routerPush(path, queryParams = undefined, params = undefined, locale = true) {
let fullPath = this.$route.fullPath
if (!path) {
path = this.$route.path
}
if (!params) {
params = this.$route.params
}
if (queryParams && typeof queryParams === 'object' && Object.entries(queryParams).length) {
path = path + '?' + this.toHttpParams(queryParams)
}
if (path !== fullPath) {
const route = { path, params, query: queryParams }
await this.$router.push(route)
}
}
I don't understand why they no longer handle this case internally, but this is what I have implemented in our app.
If you are already on the fullPath then dont bother pushing / replacing
const origPush = Router.prototype.push;
Router.prototype.push = function(to) {
const match = this.matcher.match(to);
// console.log(match.fullPath, match)
if (match.fullPath !== this.currentRoute.fullPath) {
origPush.call(this, to);
} else {
// console.log('Already at route', match.fullPath);
}
}
const origReplace = Router.prototype.replace;
Router.prototype.replace = function(to) {
const match = this.matcher.match(to);
// console.log(match.fullPath, match)
if (match.fullPath !== this.currentRoute.fullPath) {
origReplace.call(this, to);
} else {
// console.log('Already at route', match.fullPath);
}
}
you can add a random query parameter to push object like this:
this.$router.push({path : "/admin", query : { time : Date.now()} });
