What's the equivalent of webpack externals when using --turbo with a nextjs app?

[gpxl-dev]

Summary

I need the equivalent of this for turbopack:

const nextConfig = {
  webpack: (config) => {
    config.externals.push(
      "pino-pretty",
      "encoding"
    );
    return config;
  },
}

But can't find the option anywhere... Is it possible?

@gpxl-dev friend , did you fix it ?

[mischnic]

Use serverExternalPackages: https://nextjs.org/docs/app/api-reference/next-config-js/serverExternalPackages

const nextConfig = {
  serverExternalPackages: ['pino-pretty', 'encoding'],
}
 
module.exports = nextConfig

After having done this way, I still got the Module not found: Can't resolve 'pino-pretty' when building.

edit: found the issue: #68805

@mischnic Does't that only for server component or Route.js (Telling from docs)?
