​
Create a Vue application

Run the following command to create a new Vue application with vite: 
npm create vite@latest project-name -- --template vue-ts

​
Install @teamhanko/hanko-elements

Install hanko-elements to access the pre-built hanko-auth and hanko-profile components. Also install vue-router to handle routing and navigation. 
cd project-name
npm install @teamhanko/hanko-elements vue-router

​
Set up your Hanko project

Go to the Hanko Console and create a project for this application.
During creation make sure to input the URL you will be developing on as the APP URL.
(Most likely http://localhost:5173/)

​
Add the Hanko API URL

Retrieve your API URL from the Hanko Console, and paste this in a .env file.
.env
VITE_HANKO_API_URL=https://f4****-4802-49ad-8e0b-3d3****ab32.hanko.io
If you are self-hosting you need to provide the URL of your running Hanko backend.

​
Configure component resolution

Vue needs to know which elements to treat as custom elements, otherwise it will issue a warning regarding component resolution. To do so, provide a predicate function that determines which elements are to be considered custom elements to compilerOptions.isCustomElement in your configuration.

To do this update your vite.config.js file to:
src/vite.config.js
import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'

export default defineConfig({
  plugins: [vue({
    template: {
        compilerOptions: {
          isCustomElement: (tag) => tag.startsWith("hanko-")
        }
    }
    })],
})

​
Set up TS support for Vue components

TypeScript doesn’t understand .vue files by default, which can cause IDE errors or issues during development. To fix this we will create a new file shims-vue.d.ts in our src/ directory. Add the following content to make TS understand .vue files:
src/shims-vue.d.ts
declare module '*.vue' {
  import type { DefineComponent } from 'vue'
  const component: DefineComponent<{}, {}, any>
  export default component
}

​
Create Hanko components

Create a folder called components and create two in it, HankoAuth.vue and HankoProfile.vue.

​
Hanko Auth

Set up the HankoAuth.vue file to create a functioning login component. Here we subscribe to the onSessionCreated event, this triggers when a user successfully logs in. You can use these event to perform any desired action (e.g. redirect to your dashboard). For more information please refer to the Auth component page.
src/components/HankoAuth.vue
<script setup lang="ts">
  import { useRouter } from "vue-router";
  import { onMounted } from "vue";
  import { register } from "@teamhanko/hanko-elements";

  const hankoApi = import.meta.env.VITE_HANKO_API_URL;
  const router = useRouter();

  const redirectAfterLogin = () => {
    // successfully logged in, redirect to a page in your application
    router.push("/dashboard");
  };

  onMounted(() => {
    register(hankoApi)
      .catch((error) => {
        // handle error
        console.log(error);
      });
  });
</script>

<template>
<!-- The onSessionCreated event gets called when the user succesfully logs in -->
<hanko-auth @onSessionCreated="redirectAfterLogin" />
</template>

​
Hanko Profile

Set up the HankoProfile.vue file to create an interface where users can manage their email addresses and credentials. For more information please refer to the Profile component page.
src/components/HankoProfile.vue
  <script setup lang="ts">
    import { onMounted } from "vue";
    import { register } from "@teamhanko/hanko-elements";

    const hankoApi = import.meta.env.VITE_HANKO_API_URL;

    onMounted(() => {
      register(hankoApi).catch((error) => {
        // handle error
        console.log(error)
      });
    });
  </script>

  <template>
    <hanko-profile />
  </template>

​
Set up routes and views

To route our app we will use the RouterView component from the vue-router. First let’s set up our views which will be used by the router.

​
Create Views

Create two files, HomeView.vue and DashboardView.vue in a new directory /views. These Views will be the content that will be shown on a page.

Setup your views like this:
src/views/HomeView.vue
<script setup lang="ts">
  import HankoAuth from '../components/HankoAuth.vue'
</script>

<template>
  <main>
    <HankoAuth/>
  </main>
</template>
And:
src/views/DashboardView.vue
<script setup lang="ts">
  import HankoProfile from '../components/HankoProfile.vue'
</script>

<template>
  <main>
    <HankoProfile/>
  </main>
</template>

​
Set up router

Create a file index.ts in a new directory /router. In here we can set up the vue-router just like this:
router/index.ts
import { createRouter, createWebHistory } from 'vue-router'
import HomeView from '../views/HomeView.vue';
import DashboardView from '../views/DashboardView.vue';

const router = createRouter({
    history: createWebHistory(import.meta.env.BASE_URL),
    routes: [
      {
        path: '/', // <- path
        name: 'home',
        component: HomeView // <- view
      },
      {
        path: '/dashboard', // <- path
        name: 'dashboard',
       component: DashboardView // <- view
      }
    ]
  })

export default router
Add the <RouterView> component to your App.vue file like this:
src/App.vue
  <script setup lang="ts">
    import { RouterView } from 'vue-router'
  </script>

  <template>
      <RouterView />
  </template>
Finally intergrate the router with the app in main.ts just like this:
src/main.ts
  import { createApp } from 'vue'
  import App from './App.vue'
  import router from './router/index'

  const app = createApp(App)

  app.use(router)
  app.mount('#app')
By now you should be able to go to / to see the <HankoAuth>, and to /dashboard to see the <HankoProfile>. They should look something like this👇
sign upprofile page
If HankoAuth is not loading please restart the application as it might’ve not loaded the .env correctly the first time.

HankoProfile will only look like the picture while you are logged in.

​
Implement logout functionality

You can use @teamhanko/hanko-elements to easily logout users. Here we will make a logout button. Create LogoutButton.vue and insert the code below.
src/components/LogoutButton.vue
  <script setup lang="ts">
    import { useRouter } from "vue-router";
    import { Hanko } from "@teamhanko/hanko-elements";

    const hankoApi = import.meta.env.VITE_HANKO_API_URL;

    const router = useRouter();
    const hanko = new Hanko(hankoApi);

    const logout = () => {
      hanko.logout().catch((error) => {
        // handle error
        console.log(error)
      })
      router.push("/")//Path user will be redirected to after logging out
    }
  </script>

  <template>
    <button @click="logout">Logout</button>
  </template>
Lets add this component to our DashboardView just like this:
src/views/DashboardView.vue
<script setup lang="ts">
  import HankoProfile from '../components/HankoProfile.vue'
  import LogoutButton from '../components/LogoutButton.vue'
</script>

<template>
  <main>
    <HankoProfile/>
    <LogoutButton/>
  </main>
</template>

​
Customize component styles

You can customize the appearance of hanko-auth and hanko-profile components using CSS variables and parts. Refer to our customization guide.

​
Securing routes

To secure our routes we should validate the session token at the backend. Please refer to our backend guides. To do this we can implement middleware to our router/index.ts file. For this example we created a isUserAuthenticated function which validates our cookie using our Backend. Here we use router.beforeEach to validate our route if our route is added to the secureRoutes variable:
src/router/index.ts
import { createRouter, createWebHistory } from 'vue-router'
import HomeView from '../views/HomeView.vue';
import DashboardView from '../views/DashboardView.vue';

//Routes we want to only be accesible to authenticated users
const securedRoutes = ["dashboard"];

async function isUserAuthenticated() {
  try {
    //Change this url to the url of your running hanko backend
    const response = await fetch('http://localhost:5001/validate', {
      credentials: 'include',
    });
    return response.ok;
  } catch (error) {
    return false;
  }
}

const router = createRouter({
  history: createWebHistory(import.meta.env.BASE_URL),
  routes: [
    {
      path: '/', // <- path
      name: 'home',
      component: HomeView // <- view
    },
    {
      path: '/dashboard', // <- path
      name: 'dashboard',
      component: DashboardView // <- view
    }
  ]
})

//Middleware that runs before each navigation
router.beforeEach(async (to, from, next) => {
  //Check if you are on a secure route
  if (typeof to.name === "string" && securedRoutes.includes(to.name) && !(await isUserAuthenticated())) {
    next({ name: 'home' }); //Name of the route to redirect to if user is not authenticated
  } else {
    next();
  }
});

export default router
To verify that it works, Logout on your app and go to /dashboard, you should get redirected back!

Try it yourself

Vue example

It uses Express.js for the backend, full source code available on our GitHub.
