A cloudformation json -> cdk typescript transpiler.

cdk-from-cfn

In a world where people want to use the full extent of the cdk, there was no product that would transform all your JSON/YAML into beautiful typescript...until now.

cdk-from-cfn will take your JSON/YAML and output the equivalent typescript.

$ ./target/release/cdk-from-cfn [INPUT] [OUTPUT]
