Clean authorization control in serverless functions
In many cases, you will have to write the same authorization code in multiple functions. For example, you might want to check that the user is in the requested organization. You can share this code in a middleware. If you are using AWS Lambda, you can rely on middy.

Testing Serverless Applications on AWS
Adding the is-test flag to our object metadata gave us our way of passing some kind of test context into our workload. The next step was to make the Lambda Function capable of discovering the context and then using that to control how it behaves under test. For this we used Middy.

I also decided to use the middy library to add CORS management to our lambda function. This will allow us to call our lambda function from our frontend, without having to worry about CORS.

The Old Faithful: Why SSM Parameter Store still reigns over Secrets Manager
And if your requirements were to change at a later date, it’s straightforward to swap out SSM Parameter Store with Secrets Manager there and then. Especially if you’re accessing the relevant service through a middleware layer such as Middy for javascript Lambda functions.

Ask HN: What would be your stack if you are building an MVP today?
I mean I'm literally building an AWS lambda function that outputs HTML when it's called via API Gateway. So someone hits https://mydomain.com/mycoolpage, then the MyCoolPage AWS Lambda function is executed and outputs whatever.
If you're interested, I use https://middy.js.org/ as a middleware engine for my AWS lambda functions which I find helpful.
I use the open sourced serverless framework for doing deploys https://www.serverless.com/

How to Securely Use Secrets in AWS Lambda?
That is it from the CDK side. Now let us create the handler and retrieve that secret. I like to use middy which describes itself as "stylish Node.js middleware engine for AWS Lambda". It offers some helpful middlewares like ssm which will help us retrieve and cache values from SSM Parameter Store. (Middy provides various other official middlewares including one for Secrets Manager.) I prefer a middleware for this because it keeps the code for retrieving the secret out of your handler which should deal with actual business logic.

Lambda Powertools TypeScript is Generally Available
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.

Can AppConfig deploy secrets in Secrets Manager?
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
