nodemail-aws-ses/EmailSender.js

nodemail-aws-ses is a Node.js package that provides a simple and easy way to send emails using Amazon SES (Simple Email Service). It provides an EmailSender class that takes care of sending emails using the AWS SDK, with options for both HTML and text ema

// Import AWS SDK and load environment variables from .env file
const AWS = require("aws-sdk");
require("dotenv").config();

// Configure AWS SDK with access keys and region from environment variables
AWS.config.update({
  accessKeyId: process.env.AWS_ACCESS_KEY_ID,
  secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY,
  region: process.env.AWS_REGION,
});

// Create an SES (Simple Email Service) instance with the specified API version
const SES = new AWS.SES({ apiVersion: "2010-12-01" });

// Define the EmailSender class
class EmailSender {
  // Constructor takes recipient email, subject, plain text body, and HTML body as arguments
  constructor(to, subject, textBody, htmlBody) {
    this.to = to;
    this.subject = subject;
    this.textBody = textBody;
    this.htmlBody = htmlBody;
  }

  // Validate the email format using a regex pattern
  validateEmail(email) {
    const emailRegex = /^[\w-]+(\.[\w-]+)*@([\w-]+\.)+[a-zA-Z]{2,7}$/;
    return emailRegex.test(email);
  }

  // Asynchronous method to send the email using AWS SES
  async send() {
    // Create the email body object, including plain text and/or HTML content
    const body = {};

    if (this.textBody) {
      body.Text = {
        Charset: "UTF-8",
        Data: this.textBody,
      };
    }

    if (this.htmlBody) {
      body.Html = {
        Charset: "UTF-8",
        Data: this.htmlBody,
      };
    }

    // Define the parameters for the SES sendEmail method
    const params = {
      Destination: {
        ToAddresses: [this.to], // Set the recipient email address
      },
      Message: {
        Body: body, // Set the email content
        Subject: {
          Charset: "UTF-8",
          Data: this.subject, // Set the email subject
        },
      },
      Source: process.env.SENDER_EMAIL, // Set the sender email address from environment variable
    };

    // Try sending the email using SES and log the result, or catch and log any errors
    try {
      const result = await SES.sendEmail(params).promise();
      console.log("Email sent:", result);
    } catch (error) {
      console.error("Error sending email:", error);
    }
  }

// Export the EmailSender class for use in other modules
module.exports = EmailSender;
