next config standalone output not working

[0-don]

would be nice to make output: "standalone"working to decrease the bundle size in docker images in next.config.mjs

/** @type {import('next').NextConfig} */
const nextConfig = {
  output: "standalone",
  webpack: (config, { isServer }) => {
    config.experiments = { ...config.experiments, topLevelAwait: true };

    if (!isServer) {
      config.resolve.alias.fs = "memfs";
      config.resolve.fallback.child_process = false;
    }

    config.externals = [
      ...config.externals,
      ({ request }, callback) => {
        if (/^web-worker$/.test(request)) {
          return callback(null, request);
        }
        callback();
      },
    ];

    return config;
  },
};

export default nextConfig;

I think the issue comes from using app router instead of pages router while calling the api rpc methods

}

this error doesn't appear when using pages router

Ok, just confirming it's working for you by default on the main branch?

Are these 2 different issues then, one is about enabling standalone output, and one is about using a different router?

its the same issue and I think I got a fix for it, this way standalone works and app router aswell

/** @type {import('next').NextConfig} */
const nextConfig = {
  output: "standalone",
  webpack: (config, { isServer }) => {
    config.experiments = { ...config.experiments, topLevelAwait: true };

    if (!isServer) {
      config.resolve.alias.fs = "memfs";
      config.resolve.fallback.child_process = false;
    }

    config.externals = [
      ...config.externals,
      ({ request }, callback) => {
        if (/^web-worker$/.test(request)) {
          return callback(null, request);
        }
        callback();
      },
    ];

    if (isServer) {
      config.externals.push("monero-ts");
    }

    return config;
  },
};

export default nextConfig;

Ok great, a PR is welcome :)

I will test this further and make one if everything looks fine
