Install and Configure the facebook-login-vuejs Module

We will use an existing Vue.js Facebook login module/library found on the NPMJS with the name facebook-login-vuejs. To install it, type this command.

npm i facebook-login-vuejs


yarn add facebook-login-vuejs

Because now the Facebook Login force to use HTTPS only, we need to modify this Vue.js 2 app to run with HTTPS. Create a new file in the root of the Vue 2 project folder called `vue.config.js` then add these lines of server configuration.

module.exports = {
    devServer: {
        open: process.platform === 'darwin',
        host: '',
        port: 8085, // CHANGE YOUR PORT HERE!
        https: true,
        hotOnly: false,

Display Sign In With Facebook Button and Basic User Profile

Now, we will implement the Facebook Login in the Vue.js 2 application. Open and edit `src/App.vue` then replace the Vue <template> content with these.

  <div id="app">
    <facebook-login class="button"
    <div v-if="isConnected" class="information">
      <h1>My Facebook Information</h1>
      <div class="well">
        <div class="list-item">
          <img :src="picture">
        <div class="list-item">
        <div class="list-item">
        <div class="list-item">

Inside the <script>, add an import of facebook-login-vuejs module.

import facebookLogin from 'facebook-login-vuejs'

Add these variables for login status and FB graph API fields after the app name.

data() {
  return {
    isConnected: false,
    name: '',
    email: '',
    personalID: '',
    picture: '',
    FB: undefined

Declare the facebookLogin in the Vue.js components.

components: {

Add these methods or functions of user data, sdkLoaded, login, and logout.

methods: {
  getUserData() {
    this.FB.api('/me', 'GET', { fields: 'id,name,email,picture' },
      user => {
        this.personalID =; =; =;
        this.picture =;
  sdkLoaded(payload) {
    this.isConnected = payload.isConnected
    this.FB = payload.FB
    if (this.isConnected) this.getUserData()
  onLogin() {
    this.isConnected = true
  onLogout() {
    this.isConnected = false;

Finally, add or replace these CSS code to the <style> tag.

#app {
  display: flex;
  flex-direction: column;
  align-items: flex-start
.information {
  margin-top: 100px;
  margin: auto;
  display: flex;
  flex-direction: column;
.well {
  background-color: rgb(191, 238, 229);
  margin: auto;
  padding: 50px 50px;
  border-radius: 20px;
  /* display:inline-block; */
.login {
  width: 200px;
  margin: auto;
.list-item:first-child {
  margin: 0;
.list-item {
  display: flex;
  align-items: center;
