https://github.com/Marukome0743/rspack-manifest

To Reproduce

Run create-next-app@canary -e reproduction-template to use repro template.
Install @next/plugin-rspack to use Rspack. (e.g. npm install @next/plugin-rspack)
Add @next/plugin-rspack settings to next.config.ts.

next.config.ts code

import withRspack from "@next/plugin-rspack";
import type { NextConfig } from "next";

const nextConfig: NextConfig = {
  /* config options here */
  reactStrictMode: true,
};

export default withRspack(nextConfig);

Make manifest.ts file in the app directory.

manifest.ts code

import type { MetadataRoute } from 'next'
 
export default function manifest(): MetadataRoute.Manifest {
  return {
    name: 'Next.js App',
    short_name: 'Next.js App',
    description: 'Next.js App',
    start_url: '/',
    display: 'standalone',
    background_color: '#fff',
    theme_color: '#fff',
    icons: [
      {
        src: '/favicon.ico',
        sizes: 'any',
        type: 'image/x-icon',
      },
    ],
  }
}

Run next dev in the terminal.
