Docs: Addressing "API Routes Response Size Limited to 4MB" Error in Next.js

[lucajung]

What is the improvement or update you wish to see?

"Addressing "API Routes Response Size Limited to 4MB" Error in Next.js" does not seem to apply to App Router, although App Router has been selected.

Is there any context that might help us understand?

Is there another solution for the App Router? Then please add it to this document.

Does the docs page already exist? Please link to it.

Bumping this up as there still doesn't seem to be a solution even though app router is the new standard.

When I try to build with this in my route.js file,

export const config = {
  api: {
    responseLimit: '5mb',
  },
}

I get this error:

Error: Page config in /next-example/src/app/api/load/route.js is deprecated. Replace `export const config=…` with the following:
Visit https://nextjs.org/docs/app/api-reference/file-conventions/route-segment-config for more information.

However, https://nextjs.org/docs/app/api-reference/file-conventions/route-segment-config doesn't any any options for setting the api response limit.

What is the solution / workaround for app router?

Seems that in app router you have to do:

const nextConfig = {
  experimental: {
    serverActions: {
      bodySizeLimit: '15mb'
    }
  }
}

in the next.config.js file
