One more question, I tried this exampl https://github.com/pulumi/examples/tree/master/cloud-ts-url-shortener , I see that it's written in typescript. But I didn't see the transpile process typescript => javascript . Is it handled automatically by palumi? or how does it works?

"Pulumi supports TypeScript natively so you don’t need to explicitly run tsc on your program before running pulumi"

Woah, great.
