curious if anyone has a good example TS code for creating resources if param was passed in or not and returning either the string returned, or the pulumi equivalent. For example, if in a config file a certificate arn is passed in, then use that cert arn when creating a cloudfront resource, but if the cert isn’t passed in, then create the cert and pass in the cert arn

I tend to wrap all the infra in classes, init all the infra in the constructor and then have readonly fields to pass things between different stacks/classes/pieces of infra

If that works :thumbsup: I’m attaching what is (perhaps) a cleaner implementation.

`config.get()` will return `undefined` if that key isn’t there, so the `|| "";` is probably unnecessary. Undefined also lets you use the <https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Conditional_Operator|ternary operator i>n line 14 of this snippet.

This lets the `createCertificate` function to remain pretty simple.

Just note, the `createCertificate` function uses the same resource name every time. So if you need to call it more than once, you’ll need to come up with a way to make `my-cert` unique each call.
