Embedded Login Integration (Vue.js)

Overview

In this quickstart, we will embed Frontegg login box to your Vue application.


The code in the sample below is available in our Frontegg Samples repository


⚡ Before you start: ⚡

📘

Getting your Frontegg subdomain

Frontegg creates a unique subdomain and client id for every environment created on the account. In order to retrieve the clientId subdomain that will act as the baseUrl in the integration, navigate to your workspace 'Settings' menu, 'Domains' and copy the Frontegg domain and clientId.

You will need them for this guide.

STEP 1: Create a New Vue application

If you have an existing app, skip this step.

To create a new app, use the following script.

vue create my-project
cd my-project

STEP 2: Install Frontegg Libraries

Run the following command to Install frontegg Vue.JS library.

// for Vue.JS v3.x
npm install @frontegg/vue vue-router

// for Vue.JS v2.x
npm install @frontegg/vue vue-router@3
// for Vue.JS v3.x
yarn add @frontegg/vue vue-router

// for Vue.JS v2.x
yarn add @frontegg/vue vue-router@3

STEP 3: Configuration

Add Frontegg to the main application.


import { createApp } from "vue";
import App from "./App.vue";
import { Frontegg } from "@frontegg/vue";
import { createRouter, createWebHistory } from "vue-router";

const router = createRouter({
  history: createWebHistory("/"),
  routes: [
    { name: "HomePage", path: "/", component: App },
  ],
});

const app = createApp(App).use(router);

app.use(Frontegg, {
  contextOptions: {
    baseUrl: "https://[YOUR_SUBDOMAIN].frontegg.com",
  },
   authOptions: {
    // keepSessionAlive: true // Uncomment this in order to maintain the session alive
  },
  hostedLoginBox: false,
  router,
});

app.mount("#app");
import Vue from 'vue'
import App from './App.vue'
import VueRouter from 'vue-router'
import { Frontegg } from '@frontegg/vue';

Vue.use(VueRouter)
const router = new VueRouter({
  mode: 'history',
});


Vue.use(Frontegg, {
  contextOptions: {
    baseUrl: 'https://[YOUR_SUBDOMAIN].frontegg.com',
  },
   authOptions: {
  // keepSessionAlive: true // Uncomment this in order to maintain the session alive
  },
  hostedLoginBox: false,
  router,
});

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

Wrap your application on the fronteggLoaded attribute to make sure you have the right context.

<template>
  <div id="app" v-if="fronteggLoaded">
    <img alt="Vue logo" src="./assets/logo.png" />
  </div>
</template>

STEP 4: Getting the user context

Frontegg exposes the user context and the authentication state via a global set of mixins and state mappers. You can access the authentication state via the mappedAuthState as in the following sample:

📘

Composition API is supported for @frontegg/[email protected]

<template>
  <div id="app" v-if="fronteggLoaded">
    <div v-if="authState.user">
      <span>Logged in as: {{ authState.user.name }}</span>
    </div>
    <div>
      <button v-if="authState.user" v-on:click="logout">Logout</button>
      <button v-if="authState.user" v-on:click="showAccessToken">
        What is my access token?
      </button>
      <button v-if="!authState.user" v-on:click="goToLogin">Login</button>
    </div>
  </div>
</template>

<script>
import {
  useFrontegg,
  useFronteggAuthGuard
} from "@frontegg/vue";
import { useRouter } from "vue-router";

export default {
  setup() {
    useFronteggAuthGuard(); // auto redirects the user to login / application
    
    const router = useRouter();

    const { fronteggLoaded, authState } = useFrontegg();

    const goToLogin = () => {
      router.push("/account/login");
    };
    const logout = () => {
      router.push("/account/logout");
    };
    const showAccessToken = () => {
      alert(authState.user.accessToken);
    };

    return {
      fronteggLoaded,
      authState,
      goToLogin,
      logout,
      showAccessToken,
    };
  },
};
</script>
<template>
  <div id="app" v-if="fronteggLoaded">
    <div v-if="this.authState.user">
      <span>Logged in as: {{this.authState.user.name}}</span>
    </div>
    <div>
      <button v-if="this.authState.user" v-on:click="logout">Logout</button>
      <button v-if="this.authState.user" v-on:click="showAccessToken">What is my access token?</button>
      <button v-if="!this.authState.user" v-on:click="goToLogin">Login</button>
    </div>
  </div>
</template>

<script>
export default {
  name: "App",
  methods: {
    goToLogin() {
      this.$router.push('/account/login');
    },
    showAccessToken() {
      alert(this.authState.user.accessToken);
    },
    logout() {
      this.$router.push('/account/logout');
    }
  },
  data() {
    return {
      ...this.mapAuthState(),
    }
  }
};
</script>

STEP 5: Run the app, signup & login

We are all set. Let's run the application and see Frontegg in action.

npm run serve
yarn run serve

Great, Frontegg is now integrated with your app!

Login and logout routes have been added to your app:

  • Signup screen is at http://localhost:8080/account/sign-up
  • Login screen is at http://localhost:8080/account/login

If you are already logged in, go to http://localhost:8080/account/logout and log out.

Give it a try now!

Open http://localhost:8080/account/sign-up and sign up with your first user.
