Disable build-time fetching in CI environment?

[kevineinarsson]

Hey,

I've got a project which has a GraphQL-backend from which it gets props in getStaticProps (fully static pages) on which I'd like to run some tests and build in isolation. Right now my builds fail because of gSP as it cannot access the backend.

I was hoping there would be an environment variable or config setting I could use to bypass data fetching. Perhaps just a environment variable and if that's set, return an empty props object(?).

Does anyone have any experience with a similar situation? Maybe the solution to spin up a mock graphql backend in the CI environment?

Why you can't do this inside getStaticProps? Maybe also some error control when you're using other code to catch/login data, so your build will not crash.

export const getStaticProps: GetStaticProps = async () => {

const data = await getData;

if(data)
  return {
    propsData
  };
} else {
  return {
    propsWithoutData
  };
}

Oh, of course how did that slip my mind 🤦 ... thanks. :)
