Is it normal that router's size is over 16000kb?

import { auth } from "@myapp/auth";
import { createFileRoute } from "@tanstack/react-router";

export const Route = createFileRoute("/api/auth/$")({
    server: {
        handlers: {
            GET: ({ request }) => {
                return auth.handler(request);
            },
            POST: ({ request }) => {
                return auth.handler(request);
            },
        },
    },
});

import { createContext } from "@myapp/api/context";
import { appRouter } from "@myapp/api/routers/index";
import { createFileRoute } from "@tanstack/react-router";
import { fetchRequestHandler } from "@trpc/server/adapters/fetch";

function handler({ request }: { request: Request }) {
    return fetchRequestHandler({
        req: request,
        router: appRouter,
        createContext,
        endpoint: "/api/trpc",
    });
}

export const Route = createFileRoute("/api/trpc/$")({
    server: {
        handlers: {
            GET: handler,
            POST: handler,
        },
    },
});
