VITE.JS SSR Not Working with react-router-dom

I been trying to create template with Vite SSR with react-router-dom for my requirements. i know Next JS is better alternative for Vite SSR.

heare i have some configs that i made for this template.

Vite.config.ts

import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react-swc'
import path from 'path'

export default defineConfig({
    plugins: [react()],
    ssr: {
        external: [
            'react-router-dom'
        ]
    },

    resolve: {
        alias: {
            "@App": path.resolve(process.cwd(), "src"),
            "@Components": path.resolve(process.cwd(), "src/Components"),
            "@Pages": path.resolve(process.cwd(), "src/pages"),
            "@Styles": path.resolve(process.cwd(), "src/Styles"),
            "@Public": path.resolve(process.cwd(), "public")
        },
    },
})

Src/App.tsx

import { BrowserRouter } from "react-router-dom";


function Application() {
    return (
        <BrowserRouter>
            HI
        </BrowserRouter>
    );
}

export default Application;
