Discussion on "Send an SNS notification using AWS Lambda"

Welcome! Today, I am going to show you how to write an AWS Lambda Function that sends an SNS notification. 🐦 Follow me on Twitter if you would like to see more content like this! 🐦 TLDR - Here is a link to my Github with the given code. 1. Initial...

Interesting, nice article! Is it possible to send any type of notifications? For example, a notification every time someone replies to your tweet?

I know the example is pointless, but just trying to understand how one can use it. 😊

AWS SNS can send messages to many kinds of subscribers: HTTP webhooks, Email, SMS, SQS, Push notification.

In order to trigger it, you can use Lambda like this article shows, or EventBridge. The possibilities are endless.

Benoît Bouré, go it! Thanks!

I also followed you on Twitter just now.

Catalin Pit thank you for reading!

My use case for this is to be used doing live sporting events. I write software to score different types of sports in realtime. I use AWS Lambda and AWS CloudWatch Event Rules to periodically (CRON) query our database to find potential errors. If there are errors our team is notified immediately. Some of our team members get emails while others prefer SMS.

I have an article on deck to query an RDS database using AWS Lambda. Stay tuned!

Great article Phillip Ninan

I just wanted to bring something to your attention. With the aws-sdk, you can either use the callback function (on the request method) - OR - use .promise() with .then() or await. It seems you have made a mix of moth here. The .promise() method does not take a callback.

Did I miss something?

Benoît Bouré No, you are correct! I forgot to add a .then(). I updated the article and the Github source code. Ironically, the code still executed properly with this error, but the logs were never printed.

Thank you for pointing that out!!
