On Google Cloud, resources need to be created in a Google Cloud Project. I have a custom component around some Google Cloud networking. I would very much like to pass a full object rather than a primitive to my abstraction. What do I mean with this? Well, I do not want to pass the project id as a
string
. I would like to pass a full object. The problem I have is this: if the project is created in the same stack, I have a
gcp.organizations.Project
instance, with
Output
properties. If the project was already created in another stack, I look it up via
getProject
and I am returned a
Promise<GetProjectResult>
. The properties of a
GetProjectResult
instance are the primitive types (not
Output
). So I can’t substitute one for the other just because the resource is created in another stack. Any way around this?

Wrapping both in an output should give you the same effect for both, to get the projectId you would do
project.apply(p => p.projectId)
One will unwrap the promise to an output of the object with primitives and the other will traverse the object to have all the outputs as primitives during the apply

But in Typescript, what is the common “type” here I can set in my component constructor? I hope not
any
.
constructor(project: <which type here?>)

I'm not sure if what those types resolve actually intersect but going for the safe route you could do
Input<Project|GetProjectResult>
and then do
project = output(project)
before using it on your component

Your
|
character made me think about having
or
-types to indicate one or the other:
constructor(project: gcp.organizations.Project | Promise<gcp.organizations.GetProjectResult>)
My editor is not complaining… will see how far I can get with this.

I would still prefer using
Input
wrapping them on the argument list to allow the values to be passed both directly, as promise or as output

Why do you prefer it that way? Because it is clearer referring to an
Input
or is there also another technical thing I’m missing here?

Input<Project|GetProjectResult>
is the same as
Project | GetProjectResult | Promise<Project | GetProjectResult> | Output<Project | GetProjectResult>
So it will accept resources created inside an
apply
, in a promise chain or directly

Copy code
getSomeConfigsExternally().then(config => new Project(projectId: config.projectId))
