Summary

This action follows the date when AWS Lambda will mark the nodejs16.x as deprecated and precedes the date after which you will no longer be able to create new functions using the runtime.

We recommend that you upgrade your existing Node.js 16 functions to Node.js 20 before July 1st, 2024.

End of support does not impact existing functions and functions using versions of Powertools for AWS Lambda (TypeScript) released before the date, however starting from this date we will not guarantee compatibility with Node.js 16.

You can use the following AWS CLI command to list all functions in a specific region using Node.js 16, including published function versions:

aws lambda list-functions --function-version ALL --region <Region> --output text --query "Functions[?Runtime=='nodejs16.x'].FunctionArn"

Why is this needed?

Starting from July 15, 2024 we will no longer be able to deploy new Lambda functions using the nodejs16.x runtime, this means we will no longer be able to run integration tests for new code changes.

With this in mind, and considering our iteration cycles last two weeks, we plan on dropping support for the runtime just two weeks before the date.

Which area does this relate to?
