Hey all - is it possible to pass the output of one stack to another stack (example: I have two stacks and want to reference the URL of one stack in the other)

Yep you can make public variables on stack1 and pass those into stack2

@thdxr thank you for this info!

That means you can’t use…

this.addOutputs({

.

The nice thing with the variable approach is it'll be strongly typed everywhere.

this.addOutputs

would be entirely runtime

Well, I’m thinking how it should be.

@Adrián Mouly sharing local variables also uses CFN export/import. It’s equivalent to

addOutputs

in 1 stack with export, and then importing it in another stack.

I know @Frank.

I think it's actually a good thing that the user can just share variables across instances the way they'd expect in normal js/ts without knowing about the underlying mechanism. That said I wish there was a bit more convention around it, rough idea of what that could be

type Shared = { api_url: string }
class MyStack extends sst.Stack<Shared> {
  
}

const mystack = new MyStack()
const otherStack = new OtherStack({ mystack: mystack.shared})

That would keep everything fully typed

Hhmm, yeah. I tend to do:

export interface MultiStackProps extends cdk.StackProps {
  apiUrl?: sst.Api['url']
}

In the index.ts, and all my stacks implement that interface for their props.
