Is there any tutorial/guide on how to use custom-domain with API Construct and SEED stages?

SEED stages are passed into the build command

sst deploy --stage STAGE

, you can configure the domain like:

sst.Api(this, "Api", {
  customDomain: app.stage === "prod"
    ? "<http://api.mydomain.com|api.mydomain.com>"
    : `${app.stage}.<http://api.mydomain.com|api.mydomain.com>`,
  ...
});

Is this what you are looking for?

Yeah actually I used this..

customDomain: `api.${scope.stage}.<http://company-dev.net|company-dev.net>`,

But on SEED is using my local

sst.json

config, not the stage from SEED. My json is:

{
  "name": "mycompany",
  "stage": "local",
  "region": "ap-southeast-1",
  "lint": false,
  "typeCheck": false
}

Hey @Adrián Mouly, you mean if you

scope.stage

has the stage from

sst.json

, not the stage on Seed?

Yeah, found the issue, sorry, I was building the app with NPM and also SEED was building the app with YARN.
