Since I've seen Hashicorp Terraform, I have been wondering why the "plan" it can export has binary format.

Now in the AWS world you have got a declarative configuration language called CloudFormation which can be abstracted from using AWS CDK (Cloud Development Kit) in a common programming language of your choice.

Therefore my question: imagine somebody familiar with CloudFormation would like to see what CDK code will do. Is there a way to export a CloudFormation file using CDK?

Yes: in the hello world CDK example, they call it "synthesizing":

cdk synth

^^ produces CloudFormation file.

As Tamara had already mentioned, CDK already produces this for you during synthesis. To clarify this further, if you look in the cdk.out directory, you'll find a xxxxx.template.json file for every stack.

This is your synthesized template that CDK passes onto Cloudformation.

Additionally, you may also benefit from taking a look at cdk diff.

The cdk diff command compares the current version of a stack defined in your app with the already-deployed version, or with a saved AWS CloudFormation template, and displays a list of changes.

Let me know if you have any further questions!
