Sending SES email from AWS Lambda - Node JS Error "Cannot find module 'nodemailer"

Question

I have this error message: "errorMessage": "Cannot find module 'nodemailer'"

I Googled, and it says install nodemailer. Can someone tell me where exactly do I install this module? I am new to Lambda.

My Lambda function is below :

    var aws = require("aws-sdk");
var nodemailer = require("nodemailer");

var ses = new aws.SES();
var s3 = new aws.S3();

exports.handler = (event, context, callback) => {
callback(null, 'Hello from Lambda');
};

You should install module nodemailer in your local, then copy all files and input to lambda — Kedarnag Mukanahallipatna

I am using Windows desktop machine. Should I install nodemailer on my Windows desktop and then copy all files and input to Lambda? How do I copy files into Lambda? I thought Lambda is only for writing code, and no storage. Could you please give me an example? or step by step guide to do this? THank you. — jcoder

you need to package your code with appropriate dependencies and deploy it on lambda using ZIP. More details you can get here: docs.aws.amazon.com/lambda/latest/dg/… — Varun Chandak

You'll have to initialize your project locally npm init
Install nodemailer - npm i nodemailer
You should zip your project directory, upload it to lambda by selecting Upload a .ZIP file in the function code window.
Now you'll get an option to test.
Just put all the code in index.js for your initial tests, later you can move it around.

Thanks bro for the detailed steps, it really worked for me :) Glad to set up my first Lambda function. I am trying to send out a test email when a SQS message arrives. Hope I can do it
