SendGrid Vue

This tutorial is an extension of the [SendGrid Transactional Email Guide](/lessons/sendgrid-transactional-email-guide/). You must have the Cloud Functions deployed to start sending email from your frontend app.

Initial Setup

Start by installing the Firebase Web SDK, then initialize the packages in the root of the project. Vuefire can be installed as well, but is not required for this feature.

file_type_js_official firebase.js
import firebase from 'firebase/app';
import 'firebase/auth';
import 'firebase/functions';

const config = {
 // your firebase config


export const app =;
export const auth = firebase.auth();
export const functions = firebase.functions();

Transactional Email Component

The Vue component uses the beforeCreate lifecycle hook to monintor to the user’s auth state, while sendEmail references the callable function deployed to Firebase.


  <div v-if="user">
    {{ JSON.stringify(user) }}
    <button v-on:click="sendEmail()">Send Email with Callable Function</button>
    <button v-on:click="signOut()">Sign Out</button>

  <div v-else>
    <button v-on:click="signInWithGoogle()">Login with Google</button>



import * as firebase from 'firebase/app';
import { auth, functions } from '../firebase';

export default {
  name: 'HelloWorld',
  data: function () {
    return {
      user: null
  beforeCreate: function() {
    firebase.auth().onAuthStateChanged((user) => {
      this.user = user;
  methods: {
    signInWithGoogle: function() {
      return auth.signInWithPopup(new firebase.auth.GoogleAuthProvider())
    signOut: function() {
      return auth.signOut();
    sendEmail: function() {
      const callable = functions.httpsCallable('genericEmail');
      return callable({ text: 'Sending email with Vue and SendGrid is fun!', subject: 'Email from Vue'}).then(console.log);
