Input<T>

includes

Promise<T>

. You should be able to just pass through the promise.

Yes - you can. You are possibly struggling most with this at top level in your Node modules (or index.ts), where JavaScript does not directly support `async`/`await`. You can work around this by putting your code inside

async function main() { ... }

and then invoking

main()

at top level.

Ha. Thanks. Good to know - I guess this top level trick was one of the missing pieces. I'll try again just knowing that it should work fine and see where I get stuck.

Thanks for the help @white-balloon-205 and others - I'm able to use async now 🙂 One remaining question - I'm updating some external api based on a pulumi resource (e.g. in an

output.apply

), this is executed even on previews or when the resource hasn't changed. I presume a better way to do this is to create a Custom Resource? Are there any examples of how to do that - or other recommended patterns?

there's a "dynamic provider" examples are in this repo: https://github.com/pulumi/pulumi/blob/master/examples/dynamic-provider/derived-inputs/index.ts i've had problems with it though - it serializes the source code into the stack and because it gets serialized differently on linux and windows it causes unnecessary changes for some of our team

ok great, thanks @better-rainbow-14549. I'll take a look a look at that.
