Note

We will be using ES2015 in the code samples in the guide.

Also, all examples will be using the full version of Vue to make on-the-fly template compilation possible. See more details here.

Creating a Single-page Application with Vue + Vue Router is dead simple. With Vue.js, we are already composing our application with components. When adding Vue Router to the mix, all we need to do is map our components to the routes and let Vue Router know where to render them. Here's a basic example:

HTML

<script src="https://unpkg.com/vue/dist/vue.js"></script>
<script src="https://unpkg.com/vue-router/dist/vue-router.js"></script>

<div id="app">
  <h1>Hello App!</h1>
  <p>
    <!-- use router-link component for navigation. -->
    <!-- specify the link by passing the `to` prop. -->
    <!-- `<router-link>` will be rendered as an `<a>` tag by default -->
    <router-link to="/foo">Go to Foo</router-link>
    <router-link to="/bar">Go to Bar</router-link>
  </p>
  <!-- route outlet -->
  <!-- component matched by the route will render here -->
  <router-view></router-view>
</div>

JavaScript

// 0. If using a module system (e.g. via vue-cli), import Vue and VueRouter
// and then call `Vue.use(VueRouter)`.

// 1. Define route components.
// These can be imported from other files
const Foo = { template: '<div>foo</div>' }
const Bar = { template: '<div>bar</div>' }

// 2. Define some routes
// Each route should map to a component. The "component" can
// either be an actual component constructor created via
// `Vue.extend()`, or just a component options object.
// We'll talk about nested routes later.
const routes = [
  { path: '/foo', component: Foo },
  { path: '/bar', component: Bar }
]

// 3. Create the router instance and pass the `routes` option
// You can pass in additional options here, but let's
// keep it simple for now.
const router = new VueRouter({
  routes // short for `routes: routes`
})

// 4. Create and mount the root instance.
// Make sure to inject the router with the router option to make the
// whole app router-aware.
const app = new Vue({
  router
}).$mount('#app')

// Now the app has started!

By injecting the router, we get access to it as this.$router as well as the current route as this.$route inside of any component:

// Home.vue
export default {
  computed: {
    username () {
      // We will see what `params` is shortly
      return this.$route.params.username
    }
  },
  methods: {
    goBack () {
      window.history.length > 1
        ? this.$router.go(-1)
        : this.$router.push('/')
    }
  }
}

Throughout the docs, we will often use the router instance. Keep in mind that this.$router is exactly the same as using router. The reason we use this.$router is because we don't want to import the router in every single component that needs to manipulate routing.

You can also check out this example live.

Notice that a <router-link> automatically gets the .router-link-active class when its target route is matched. You can learn more about it in its API reference.
