How to stop build programatically in Next.js

Question

Is there a way to stop npm run build programatically in Next.js as soon as a certain Error occurs in getStaticProps? Just throwing an Error does not stop the build process.

Answer 1

I've been trying to achieve the same thing but apparently there is no official way. What I've tried is the following code inside next.config.js:

module.exports = async (phase, { defaultConfig }) => {
  try {
    console.log("fetching app info", phase)
    const appInfo = await fetchAppInfo()
    fs.writeJson("./src/appInfo.json", appInfo)
  } catch (e) {
    console.log(e)
    throw e
  }

  return yourConfig
}

If you don't return the expected config for next js, the build procedure will be cancled
