+# 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 tseslint.config({
+ languageOptions: {
+ // other options...
+ parserOptions: {
+ project: ['./tsconfig.node.json', './tsconfig.app.json'],
+ tsconfigRootDir: import.meta.dirname,
+ },
+ },
+})
+```
+
+- Replace `tseslint.configs.recommended` to `tseslint.configs.recommendedTypeChecked` or `tseslint.configs.strictTypeChecked`
+- Optionally add `...tseslint.configs.stylisticTypeChecked`
+- Install [eslint-plugin-react](https://github.com/jsx-eslint/eslint-plugin-react) and update the config:
+
+```js
+// eslint.config.js
+import react from 'eslint-plugin-react'
+
+export default tseslint.config({
+ // Set the react version
+ settings: { react: { version: '18.3' } },
+ plugins: {
+ // Add the react plugin
+ react,
+ },
+ rules: {
+ // other rules...
+ // Enable its recommended rules
+ ...react.configs.recommended.rules,
+ ...react.configs['jsx-runtime'].rules,
+ },
+})
+```
