Is it possible to detect if an action was taken in an output apply? i.e. create, update

you mean like
```// pseudo code
const resource1 = new pulumi.resource()
resource.apply(val =&gt; {
   const resource2 = new pulumi.resource()
})```
and see if resource 2 gets updated?

Because I have noticed that if I create resource inside of an apply it doesn't show up until the update is actually run. IE, preview doesn't show anything

which I think make sense because it wouldn't know the value of the output until it is actually run

No. I know you can’t create resources inside an apply. What I am looking to do is perform a validation inside of an apply something like this:
```resource.apply(val =&gt; {
  if (val.wasCreate() || val.wasUpdate()) {
     validate(val)
  }
})```

As it is now, the function in apply always runs.

oh that's interesting. I see what you're getting at. I have never tried something like that. what is the downside of validating even if the resource wasn't updated?

Sorry I don't have a good answer. really just curious :smile:
