Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Lambda Powertools TypeScript is Generally Available
One final thing to consider when deciding whether to adopt Lambda Powertools is what features may be in store in the future. The more mature libraries Lambda Powertools Python and Lambda Powertools Java include a number of useful utilities that we may like to see in Lambda Powertools TypeScript. The overall Lambda Powertools Roadmap doesn't tell us very much other than pending dotnet and golang libraries, but we can drill down into TypeScript-specific issues and glimpse the immediate future. It looks like stability is still the main priority, but there are some interesting items like RFC: Testing Factories for AWS Data Objects in the leftmost column.

First Look at Lambda Powertools TypeScript
I eagerly await the general availability of this library and will follow the roadmap to see what's coming up and how I can get involved.
-
Add AWS Powertools
According to Roadmap there is some work on .Net support. Hopefully we will see it soon. Personally, I would like to see nodejs and golang support too.

AWS Lambda Powertools: Idempotency, A Deeper Dive
If switching your development to Python for AWS Lambda Powertools is not for you, I recommend heading over to the AWS Powertools Roadmap and supporting the Typescript and .NET feature requests by adding a đź‘Ť.
- TypeScript support for AWS Lambda Powertools is now on the roadmap!

The Stainless SDK Generator
What about jsii? The technology behind AWS sdks: https://aws.github.io/jsii/
Is Stainless similar, different?

AWS Makes Cloud Formation Stack Creation Up to 40% Faster
The libraries for other supported languages of CDK are built as wrappers for underlying JS or maybe TS code via https://github.com/aws/jsii
So all the core CDK code is written first in JS/TS and then stubs for the other languages are added
Unfortunately this is often done without consideration for how the other supported langs actually work, and artefacts of e.g. JS lack of support for kwargs leak through
This is why e.g. the typing in CDK Python is completely broken - pretty much uniformly the concrete types like "Resource" don't implement their corresponding interface like "IResource" (to a type checker)
(There are many other typing niggles like this but that's the most egregious and pervasive one)
At the end of the day, having to explicitly cast concrete types as their interface to satisfy type checker is a minor annoyance, albeit a stupid one that could have been avoided with more care in the core library.
I could live with that, but I encountered so many bugs and issues trying to use CDK on current project that it's now much clearer to me why every company I worked at previously was using Terraform.
Pretty sure some of those issues are ultimately CloudFormation ones. The cumbersome CF > CDK JS > CDK Python stack is great for obfuscating errors and making debugging hard or impossible though.
Pulumi do something similar, albeit with Go as the core language and Terraform underneath. From what I've seen with a little use they have a much more successful result though, Pulumi Python was not a complete mess, and deploys faster and more reliable with better error feedback. I guess they just took more care to get it right.

Infrastructure Manager: Provision Google Cloud Resources with Terraform
Every version of the CDK uses an interop layer and runs on top of the Typescript version
https://github.com/aws/jsii
And as far as TF supports services before CFT. Guess which is easier for an AWS employee to do - getting the CF service team to support a new service or just contribute to Terraform’s open source project?
I know of at least one service where the service team introduced the needed APIs and then an employee of AWS wrote the TF provider and contributed to the project before AWS’s own internal team added it to CFT.

- JSii allows code in any language to naturally interact with JavaScript classes

Cloud, why so difficult? 🤷‍♀️
To "meet developers where they are" is a beautiful tenet of AWS, and of the CDK, and inspired us to create awesome technology such as JSII and constructs.
-
Automating AWS API gateways v1 REST
Yeah both CDKTF and Pulumi piggyback on JSII, a class translator that supports the languages you've mentioned, which was used as a building base for CDK.

New open-source programming language for DevOps engineers by the creator of the CDK
The reason we chose to start with compilation to JavaScript and not some other popular cloud language is because JavaScript is currently one of the most used ones, and in addition, we are using JSII to write our SDK in Typescript and then export it for consumption in other languages, such as Go, Python, Java and others.
- Write SDK “base” in Rust, wrap in other languages?

CDKTF Frequently Asked Questions
The CDKTF CLI is implemented in TypeScript. Providers and resources are implemented in TypeScript as well. jsii is used to compile the providers and resources to the supported languages.
