VueJS route is undefined - vue.js

I'm trying to render my vue components inside the router-view tag. But it gives me an error
TypeError: route is undefined
But I didn't use the word route in anywhere. This is my code.
App.vue
<template>
<div id="app">
<my-header></my-header>
<router-view></router-view>
<my-footer></my-footer>
</div>
</template>
outerroutes.js
import welcome from './components/welcome.vue';
import insideSystem from './components/insideSystem.vue';
import forgotPassword from './components/forgotPassword.vue';
export const routes = [
{path:'',component:welcome},
{path:'/insideSystem',component:insideSystem},
{path:'/forgotPassword',component:forgotPassword}
];
main.js
import Vue from 'vue'
import App from './App.vue'
import VueRouter from 'vue-router'
import {routes} from './outerroutes';
Vue.use(VueRouter);
const router = new VueRouter({
routes,
mode:'history'
});
new Vue({
el: '#app',
routes,
render: h => h(App)
})
I'm wondering where is this route came from.

You are creating a router instance as follows;
const router = new VueRouter({
routes,
mode:'history'
});
But you should inject the router instance to router option in the root vue instance not routes
new Vue({
el: '#app',
router,
//routes, not this
render: h => h(App)
})

In outerroutes.js:
{path:'',component:welcome},
There is nothing defined. Try:
{path:'/',component:welcome},
Additionally, I'm not sure that you need the curly braces around routes in main.js at:
import {routes} from './outerroutes';

Rendering a component with router in Vue.js

My first day with Vue. I initialized my app. I want to add a Login component, when I set routes in main.js, no page works.
import Vue from 'vue'
import App from './App.vue'
import VueRouter from 'vue-router'
import Login from './components/Login.vue'
const routes = [
{ path: '/', component: App },
{ path: '/login', component: Login }
]
const router = new VueRouter({
mode: 'history',
routes
})
new Vue({
router
}).$mount("#app")
Only works when I add render option to Vue object and renders the App component.
new Vue({
router,
render: h => h(App) // or Login
}).$mount("#app")
How will I ensure rendering route components?
You should add router-view component inside your App component like :
<template>
<div>
<router-view></router-view>
</div>
</template>

why can't my <router-view> be rendered?

I am a noob to vue-router. Here is my code,I want to render User compoent, when I navigate to http://localhost:8080/users
App.vue file:
<template>
<div id="app">
<h1>{{msg}}</h1>
<router-view></router-view>
</div>
</template>
<script>
export default {
data () {
return {
msg: 'Welcome to Your Vue.js App'
}
}
}
</script>
Users.vue
<template>
<div>
<h1>xue yan</h1>
</div>
</template>
main.js
import Vue from 'vue'
import App from './App.vue'
import VueRouter from 'vue-router'
import Users from './Users.vue'
Vue.use(VueRouter);
const routes = [
{path:'/users',component:Users}
];
const router = new VueRouter({
routes
});
new Vue({
el: '#app',
router,
render: h => h(App)
})
But, I can't see the Users component in my index.html,when I try to navigate to "http://localhost:8080/users".All the files come from vue-cli webpack-simple. what's more, there is no error in console.I can't tell what's wrong with it.
add history mode to your router as follows
const router = new VueRouter({
mode: 'history',
routes,
});
Without history mode on you need to add # in your search like this http://localhost:8080/#/users to make it work.
More about why history mode read the docs here

Vuex: store object not visible in components

When I try to access the vuex store inside a random component, undefined is returned. However, I injected the store into my Vue object. Does anyone know how to solve this? I could import the store object into every component manually, but that's not really clean...
My files look like this:
main.js
import Vue from 'vue'
import VueResource from 'vue-resource'
import VueRouter from 'vue-router'
import VueI18n from 'vue-i18n'
import routes from './config/routes'
import locales from './lang/locales'
import store from './store'
//Routing support
Vue.use(VueRouter);
//Backend support
Vue.use(VueResource);
//Language support
Vue.use(VueI18n);
Vue.config.lang = 'nl';
Object.keys(locales).forEach(function (lang) {
Vue.locale(lang, locales[lang])
});
const router = new VueRouter({
store,
mode: 'history',
base: '/app/',
routes: routes
});
new Vue({
router
}).$mount('#app');
store/index.js
import Vue from 'vue'
import Vuex from 'vuex'
import fleet from './modules/fleet'
Vue.use(Vuex)
export default new Vuex.Store({
modules : {
fleet
}
})
app.vue
<template>
<div id="page-content-wrapper">
<nav-bar></nav-bar>
<div class="container-fluid">
<div class="row">
<router-view></router-view>
</div>
</div>
</div>
</template>
<script>
import NavBar from './assets/navBar.vue'
export default {
created() {
console.log(this.$store)
},
components: {
NavBar
}
}
</script>
this.$store returns undefined
const router = new VueRouter({
store,
mode: 'history',
base: '/app/',
routes: routes });
new Vue({
router }).$mount('#app');
Store is designed to be set up in new Vue:
new Vue({
el: '#app',
router,
store,
render: h => h(App)
})
You've placed it into VueRouter instance instead.
Proper code combined:
const router = new VueRouter({
routes,
mode: 'history',
base: ...
});
new Vue({
el: '#app',
router,
store,
render: h => h(App)
})

How to use Vue Router in Vue 2

I'm learning Vue, and started of with the webpack template. The first thing I'm trying to do is to add support for Vue Router, but I've spent several hours on it now without being able to render a single route (I always end up with a blank page). Frustrating!
I simply want to have a single .vue file, acting as the layout file, into which different .vue files, acting as "pages", are rendered into. Can someone tell me how to do this, please? Here's my latest failed attempt:
main.js
import Vue from 'vue'
import VueRouter from 'vue-router'
import App from './App'
import Home from './components/Home'
import About from './components/About'
Vue.use(VueRouter)
const routes = [
{ path: '/', component: Home },
{ path: '/about', component: About }
]
const app = new Vue({
router: new VueRouter({
routes
}),
component: App
}).$mount('#app')
App.vue (the layout file)
<template>
<div id="app">
<h1>Hello App!</h1>
<p>
<router-link to="/">Go to Foo</router-link>
<router-link to="/about">Go to Bar</router-link>
</p>
<router-view></router-view>
</div>
</template>
<script>
export default {
}
</script>
<style scoped>
</style>
components/About.vue (almost identical to components/Home.vue)
<template>
<div>
<h1>About</h1>
<p>This is the about page!</p>
</div>
</template>
<script>
export default {
}
</script>
<style scoped>
</style>
I finally got it to work. The main.js file should be written like this:
import Vue from 'vue'
import VueRouter from 'vue-router'
import App from './App'
import Home from './pages/Home'
import About from './pages/About'
Vue.use(VueRouter)
const routes = [
{ path: '/', component: Home },
{ path: '/about', component: About }
]
const router = new VueRouter({
routes
})
const app = new Vue({
router,
template: '<App />',
components: {
App
}
}).$mount('#app')
I hope this saves hours of trouble for someone else.
EDIT
The following:
const app = new Vue({
router,
template: '<App />',
components: {
App
}
}).$mount('#app')
can preferably be replaced with:
const app = new Vue({
router,
render: function(createElement){
return createElement(App)
}
}).$mount('#app')
I found out how to get main.js to call the index.js file in folder router and work with the routes defined there:
I had created my app via the VUE UI (with VUE 3.1 and CLI/3)
In the VUE UI there is an option to add plugins. I chose the router plugin (route) and it asked if I want to install a new route or install the framework. (You first need to install the framework...)
It then changed my main.js file to have the following: (the additions are marked with comments)
import Vue from 'vue'
import './plugins/axios'
import App from './App.vue'
import router from './router' // added by router plugin
Vue.config.productionTip = false
new Vue({
router, // added by router plugin
render: h => h(App)
}).$mount('#app')
It also added a new folder router and in it index.js with the code
import Vue from 'vue'
import VueRouter from 'vue-router'
// import Hello from '#/components/HelloWorld' // #pashute: I added this later...
Vue.use(VueRouter)
const routes = [
// {
// path: '/',
// name: 'Hello',
// component: Hello
// }
]
// eslint-disable-next-line no-new
const router = new VueRouter({
routes
})
export default router
It also installed the latest router package and added a link in the HelloWorld component to the router documentation.
By the way, notice the extra name: in the route definitions.

I do not know what's wrong with the code, the <router-view> do not update when I change the route.
I think your app is not properly initialized yet. You are starting your app as follows:
new Vue({
router,
store,
...App
}).$mount('#app')
You have the spread operator ...App, which is not necessary - it is used to convert array items to function args, and not correct in this context. Instead you should use the render function as provided in webpack template :
/* eslint-disable-line no-new */
new Vue({
el: "#app",
store,
router,
render: h => h(App)
})
Also you have attempted to import loader in routes and index, which is not necessary if you are using vue-cli.
Maybe you can start with the webpack template as base and slowly add functionality one step at a time: start with route definitions and your route components, ensure that everything works, and finally add vuex.
$mount('#app') is fine, I think the problem is your routes.js
Try this instead:
import Index from './../views/index.vue'
const routes = [
{ path: '/index', name: 'index', component: Index }
]
And here is a working webpack template which is already configured vue-router and vuex properly, you can initialize this template via vue-cli, for your reference: https://github.com/CodinCat/vue-webpack-plus
