+# React + TypeScript + Vite
 
+
 
+This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
 
+
 
+Currently, two official plugins are available:
 
+
 
+- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react/README.md) uses [Babel](https://babeljs.io/) for Fast Refresh
 
+- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
 
+
 
+## Expanding the ESLint configuration
 
+
 
+If you are developing a production application, we recommend updating the configuration to enable type aware lint rules:
 
+
 
+- Configure the top-level `parserOptions` property like this:
 
+
 
+```js
 
+export default {
 
+  // other rules...
 
+  parserOptions: {
 
+    ecmaVersion: 'latest',
 
+    sourceType: 'module',
 
+    project: ['./tsconfig.json', './tsconfig.node.json', './tsconfig.app.json'],
 
+    tsconfigRootDir: __dirname,
 
+  },
 
+}
 
+```
 
+
 
+- Replace `plugin:@typescript-eslint/recommended` to `plugin:@typescript-eslint/recommended-type-checked` or `plugin:@typescript-eslint/strict-type-checked`
 
+- Optionally add `plugin:@typescript-eslint/stylistic-type-checked`
 
+- Install [eslint-plugin-react](https://github.com/jsx-eslint/eslint-plugin-react) and add `plugin:react/recommended` & `plugin:react/jsx-runtime` to the `extends` list
