# React + TypeScript + Vite
2+
3+
This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
4+
5+
Currently, two official plugins are available:
6+
7+
- [@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
8+
- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
9+
10+
## Expanding the ESLint configuration
11+
12+
If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
13+
14+
```js
15+
export default tseslint.config({
16+
extends: [
17+
// Remove ...tseslint.configs.recommended and replace with this
18+
...tseslint.configs.recommendedTypeChecked,
19+
// Alternatively, use this for stricter rules
20+
...tseslint.configs.strictTypeChecked,
21+
// Optionally, add this for stylistic rules
22+
...tseslint.configs.stylisticTypeChecked,
23+
],
24+
languageOptions: {
25+
// other options...
26+
parserOptions: {
27+
project: ['./tsconfig.node.json', './tsconfig.app.json'],
28+
tsconfigRootDir: import.meta.dirname,
29+
},
30+
},
31+
})
32+
```
33+
34+
You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
35+
36+
```js
37+
// eslint.config.js
38+
import reactX from 'eslint-plugin-react-x'
39+
import reactDom from 'eslint-plugin-react-dom'
40+
41+
export default tseslint.config({
42+
plugins: {
43+
// Add the react-x and react-dom plugins
44+
'react-x': reactX,
45+
'react-dom': reactDom,
46+
},
47+
rules: {
48+
// other rules...
49+
// Enable its recommended typescript rules
50+
...reactX.configs['recommended-typescript'].rules,
51+
...reactDom.configs.recommended.rules,
52+
},
53+
})
54+
```
