How to Send Emails in Node.js

In this article, we will learn how to send emails in node.js. We all receive email on daily basis, and it is one of the most crucial forms of communication today so knowing how to send one using node.js is quite awesome and useful

Introduction to Superface.ai

I am going to use Superface for API integration as it makes the integration super easy. I don’t have to deal with API docs, and I can use many providers using the same interface. Furthermore, I can use more ready-made API use cases from Superface catalog. Learn one to conquer all.

Create a Node.js Project

mkdir sendEmail
cd sendEmail
npm init -y

Installing Superface SDK

npm i @superfaceai/one-sdk

Then choose your use case. We are going to use Send Email | Superface.

Now you have to configure the provider you want to use I am going with SendGrid. First, create your account get your api key and verify Single Sender Verification

I am using https://emailfake.com/ to get some temporary emails.

Back in Superface, copy and paste the code from the example and replace the token with your key.

const { SuperfaceClient } = require('@superfaceai/one-sdk');

const sdk = new SuperfaceClient();

export default async function run(req,res) {

   const profile = await sdk.getProfile('communication/[email protected]')
  // Use the profile
  const result = await profile
    .getUseCase('SendEmail')
    .perform({
    from: '[email protected]',
        to: '[email protected]',
        subject: 'Your order has been shipped!',
        text: 'Hello Cedes, your recent order on Our Shop has been shipped.',
    }, {
      provider: 'sendgrid',
      security: {
        bearer_token: {
          token: '<your token from sendgrid>'
        }
      }
    });

  try {
    const data = result.unwrap();
    res.send(data)
  } catch (error) {
    console.error(error);
  }
}

run()

Now to check if everything works, run the application:

node index.js

We can see the email is received.

You can also send attachments like pdf files and more.
