Initial Project Setup

Create a NodeJs application using the below command. mkdir SendgridApp cd SendgridApp Initialize Project npm init -y

It will create a package.json file.

We will install the required dependencies in our project using the below command.

npm i express @sendgrid/mail dotenv

Open the root file of our project and name it as your will.

// app.js const express = require("express"); require("dotenv").config(); var app = express(); app.use(express.json()) const mailRoute = require('./routes/sendMail') app.use(mailRoute) app.listen(process.env.PORT, console.log('Server is up and running '+ process.env.PORT))

Set Up SendGrid Account

Let’s start with integrating Sendgrid.

For setting up the SendGrid account, follow these instructionsVisit SendGrid.com Create an account Choose a plan according to your requirements Generate API key For sending emails from our NodeJS app, we need to configure the SendGrid API key in the application. The SendGrid gives you the freedom to set up an email as per your requirement. We can also add and modify HTML, images, documents, etc.

// email/account.js const sgMail = require('@sendgrid/mail') require('dotenv').config() sgMail.setApiKey(process.env.SENDGRID_ API_KEY) //your sendgrid api key const sendMail = (email, name) => { sgMail.send({ To: email, // receiver email address from: 'fromemail@email.com', subject: 'here comes subject line', text: `here comes the body ${name}` }) } module.exports = { sendMail }

Send Mails using SendGrid in NodeJs App

We can use the sendgrid function wherever we want to use it, for example, when a user is registering or leaving or for some other notifications.

// sendMail.js For this example, we are sending mail for a specified route and call sendMail functions as per our requirement. const express = require('express') const { append } = require('express/lib/response') const { sendMail } = require('../emails/accounts') const statusCode = require('../constants/constants') const router = new express.Router()

router.get('/sendmail', (req, res) => { const user = req.body; try { sendMail(user.email,user.name) res.status(statusCode.ok).send({message: 'Mail Sent'}) } catch (error) { res.status(statusCode.internalServerError). send({error}) } }) module.exports = router

As for this example, we have manually set the email or other required parameters that we can send through postman.

Bingo, we sent mail successfully!
