To try this out yourself, check out the backend folder in qldb simple demo on GitHub.

The full source code can be found at QLDB Simple Demo, but lets walk through the main steps involved.

For those of you that want to take a look at the CDC Outbox style pattern with QLDB and Kinesis, Matthew Lewis has created a demo available on github which highlights this process. It is also available as a running reference example that you can play around with at demo.qldbguide.com.

The Powertools GitHub repository offers nice examples to integrate and learn from. For example here are nice example written in AWS CDK. Following I will list the features I gained some experience with.

Lambda Powertools TypeScript can't be used directly as an ES Modules dependency, but there is an issue open, so please consider adding your +1. For now, it's possible to get by with a require shim or via cjs tricks but it would be great to see native support for ES Modules in Lambda Powertools TypeScript.

for secrets, I would recommend using AWS PowerTools if you can (depending on your language) - https://github.com/awslabs/aws-lambda-powertools-python - https://github.com/awslabs/aws-lambda-powertools-typescript

The documentation for Lambda Powertools TypeScript is pretty good and provides several examples with even more on GitHub.

Last week, AWS announced the beta release of AWS Lambda Powertools Typescript. This is a suite of TypeScript utilities for AWS Lambda functions to enable the adoption of best practices in areas such as structured logging, tracing and custom metrics.
