is this an ok pattern? (referencing cross-stack in CDK)

export default function main(app: <http://sst.App|sst.App>): void {
  // Set default runtime for all functions
  app.setDefaultFunctionProps({
    runtime: 'nodejs14.x',
    tracing: Tracing.DISABLED,
  });

  const coreStack = new CoreStack(app, 'core');
  new ApiStack(app, 'api', { cognitoAuth: coreStack.auth });
}

within

CoreStack

constructor, I’m doing

this.auth = auth

(and auth is an instance of

sst.Auth

) lemme know if there’s a better way

This is the way I've seen most people do it 👍🏽

thanks! do you know the SST/CDK equivalent of

${cf:stackname.outputVar}

in Serverless Framework? or is it not possible?

hmm. on second thought, this probably doesn’t make sense to do. I was attempting something that’s probably not a good idea 😄 thanks though

@Sam Hulick did you end up finding a better pattern for this? i'm in a similar situation, though in this case i've defined a dynamoDB table whose name & arn i'd like to reference in my ApiStack. typescript is throwing a fit passing props to ApiStack, is the only other worry.

This probably needs to be documented better but you can extend the props type to include the additional props you'd need

thanks, that did the trick. i did eventually find out in another thread that it's explained in the docs here, though i clearly whiffed on finding that bit in the docs.
