03/08/2023, 8:28 PMYou won't need to use apply unless you're trying to get at those values immediately. Most of the time, values from other stacks are used in constructors of Pulumi resources, which handle Outputs correctly.

03/08/2023, 8:29 PMYou don't need to cast on these lines, unless there's something about the way you're using the values that requires this. Can you post (as text please, not a picture) how you're using these stack references?

03/08/2023, 8:41 PMI needed to concat the two Secret arays together, after reading the docs, I figured out, I think the proper way to do it. If I do not cast them, TS errors saying type mismatch.
Copy code
const secrets: pulumi.Output<aws.ecs.Secret[]> = await pulumi
.all([baseSecretArns, envSecretArns])
.apply(async ([base, env]) => {
return base.concat(env);
});astonishing-dentist-11149

03/08/2023, 9:08 PMYou don't need the async in the formal definition of the anonymous function. And you shouldn't await this.

03/08/2023, 9:09 PMThis should do the same thing:
Copy code
const secrets = pulumi
.all([baseSecretArns, envSecretArns])
.apply(([base, env]) => [...base, ...env]);little-cartoon-10569
03/08/2023, 9:11 PMIf you need to do this often, it would be more efficient to do it in the exporting stack.

03/08/2023, 9:15 PMThat is not valid syntax, base and env do not have iterators on them (Type 'Output<Secret[]>' must have a '[Symbol.iterator]()' method that returns an iterator.), but I have removed the await and async, but even with that, because I have .all returns, I would still need the as on the const variables. This just seems really bad.
Let me rethink this to see if there is a way I can do both, I think there may be a way to combine them on this side so I don't have to do all the crazy stuff. That might fix my as concern as well.

03/08/2023, 9:16 PMWhy are base and env still outputs? They're inside the apply...

03/08/2023, 9:16 PMTHis is good stuff!

03/08/2023, 9:17 PMThey end up being this type: pulumi.UnwrappedArray<aws.ecs.Secret>

03/08/2023, 9:17 PMThat should have an iterator? If not, then the .concat() optoion is fine too.

03/08/2023, 9:18 PMI don't think I am going to need it, I don't think base and env need to be seperate, ❤️ thank you! Good idea putting it on the export side.

03/08/2023, 9:19 PMYou can export all 3 sets of secrets for convenience.
