Vue-router error: TypeError: Cannot read property 'matched' of undefined

Question

I\'m trying to write my first Vuejs app. I\'m using vue-cli and simple-webpack boilerplate.

When I add vue-router links to my app component

Answer 1

The name when you add it to Vue must be router.

import router from './routes.js'

const app = new Vue({
  el: '#app',
  router,
  render: h => h(App)
})

If, for whatever reason, you want to call the variable routes you could assign it this way.

import routes from './routes.js'

const app = new Vue({
  el: '#app',
  router: routes,
  render: h => h(App)
})

Answer 2

On my Vue file I had the following code:

Then, I modified my app.js file, and place the following code:

import router from './Router/router.js'

const app = new Vue({
    el: '#app',
    router
});

Answer 3

Just to add my typo that caused this. I forgot the {} on the import

import { router } from './routes.js'  //correct
import router from './routes.js'   //causes same error

Adding to this, if you are putting the routes in the same page instead of importing it, It must be declared before the Vue component render.

Like this:-

const router = new VueRouter({
  mode: 'history',
  routes:[
    { path: '/dashboard', component: Dashboard},
    { path: '/signin', component: Signin}
  ]
});

new Vue({
  el: '#app',
  router,
  render: h => h(App)
})

Not like this :

new Vue({
  el: '#app',
  router,
  render: h => h(App)
})

const router = new VueRouter({
  mode: 'history',
  routes:[
    { path: '/dashboard', component: Dashboard},
    { path: '/signin', component: Signin}
  ]
});
