Blame for vite.config.js

import { defineConfig } from "vite";

export default defineConfig({
  build: {
    codeSplitting: false,
    emptyOutDir: false,
    outDir: "assets",
    lib: {
      entry: "app.js",
      formats: ["es"],
      fileName: () => "app.bundle.js"
    },
    rollupOptions: {}
  }
});
