GitHub - kamranahmedse/local-ses: Trap and test AWS SES emails locally

This will start the service on port 8282. Next, modify your SES client to use the local service.

import { SESClient, SendEmailCommand } from "@aws-sdk/client-ses";

const client = new SESClient({
  region: credentials.region,
  credentials: {
    accessKeyId: credentials.accessKeyId,
    secretAccessKey: credentials.secretAccessKey,
  },
  endpoint: "http://localhost:8282", // <--- Add this to trap emails locally
});

// Send emails as usual
const command = new SendEmailCommand({/*...*/});
const result = await sesClient.send(command);

logInfo(`Email sent to ${toAddress} with message ID ${result.MessageId}`);
