Advantages are:

• Terraform has a much larger user base than Pulumi and is the goto for IAC
• Terraform doesn't require an account

Terraform providers are supported via an HCL to TS generator. So Auth0 etc. should work https://www.terraform.io/docs/providers/auth0/index.html

Open questions

Auth0 dependency for building web and thus s3 files

Custom provider. Requires golang (more complicated than Pulumi) https://learn.hashicorp.com/terraform/providers/setup-implement-read

Different stacks. Isn't supported yet IDEAL SOLUTION https://github.com/hashicorp/terraform-cdk/issues/35 https://github.com/hashicorp/terraform-cdk/issues/34

Cloud invalidation

A module to handle via SQS and a lambda function. Overly complicated https://github.com/dirt-simple/terraform-aws-cloudfront-invalidation

Wrap the script around another script to do the invalidation (better but not great) LIKELY SOLUTION https://stackoverflow.com/questions/56835557/aws-cdk-post-deployment-actions

Punting for now since cdktf is very early.

main.ts is required in cdktf. Can't use index.ts or build/index.ts. Should be read from package.json main Included tsconfig.json (in cdktf init) doesn’t work with yarn workspaces with expo react-native

Hi Tiago, just sharing that I appreciated the investigation you did on this issue, and it was helpful for me to decide skipping using CDK for now.

Thank you!
