+## Use SerialPort, SQLite3 or other node-native addons in Main-process
+
+Main-process, Preload-script are also built with Vite, and they are just built as [build.lib](https://vitejs.dev/config/#build-lib).  
+So they just need to configure Rollup.

+
+```js
+export default {
+  build: {
+    // built lib for Main-process, Preload-script
+    lib: {
+      entry: 'index.ts',
+      formats: ['cjs'],
+      fileName: () => '[name].js',
+    },
+    rollupOptions: {
+      // configuration here
+      external: [
+        'serialport',
+        'sqlite3',
+      ],
+    },
+  },
+}

 ## `dependencies` vs `devDependencies`
 
 - First, you need to know if deps(npm package) are still needed after packaged.
