Class Usage in Terraform CDK

Terraform CDK for Terraform
1

Hi All,

Is there any way to use Terraform CDK w/ Typescript without using Classes.

Hey, I wondered the same when I started and I never got around implementing it. Thanks to you I now have an occasion to give this a try and this is what I came up with:

// This is a utility function that makes a generated provider functional
const functional =
  <ProviderType extends Record<string, any>>(provider: ProviderType) =>
  (s: Scope) =>
    new Proxy(provider, {
      get(target, prop: any) {
        return (name: string, options: any) =>
          new target[prop](s, name, options);
      },
    }) as {
      [Property in keyof ProviderType]: (
        name: string,
        opts: ConstructorParameters<ProviderType[Property]>[2]
      ) => ProviderType[Property];
    };

// You apply it to a provider to get a functional version
const fnAws = functional(aws);

// and to a scope to get a scoped down version on that you can call functions that return class instances
const s3Bucket = fnAws(scope).S3Bucket("foo", { foo: "bar" });

Here is a TS Playground link, please let me know if it helps you and if there are edge cases with it.
