# 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) uses [Babel](https://babeljs.io/) (or [oxc](https://oxc.rs) when used in [rolldown-vite](https://vite.dev/guide/rolldown)) for Fast Refresh
|
||||||
|
- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
|
||||||
|
|
||||||
|
## React Compiler
|
||||||
|
|
||||||
|
The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
|
||||||
|
|
||||||
|
## Expanding the ESLint configuration
|
||||||
|
|
||||||
|
If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
|
||||||
|
|
||||||
|
```js
|
||||||
|
export default defineConfig([
|
||||||
|
globalIgnores(['dist']),
|
||||||
|
{
|
||||||
|
files: ['**/*.{ts,tsx}'],
|
||||||
|
extends: [
|
||||||
|
// Other configs...
|
||||||
|
|
||||||
|
// Remove tseslint.configs.recommended and replace with this
|
||||||
|
tseslint.configs.recommendedTypeChecked,
|
||||||
|
// Alternatively, use this for stricter rules
|
||||||
|
tseslint.configs.strictTypeChecked,
|
||||||
|
// Optionally, add this for stylistic rules
|
||||||
|
tseslint.configs.stylisticTypeChecked,
|
||||||
|
|
||||||
|
// Other configs...
|
||||||
|
],
|
||||||
|
languageOptions: {
|
||||||
|
parserOptions: {
|
||||||
|
project: ['./tsconfig.node.json', './tsconfig.app.json'],
|
||||||
|
tsconfigRootDir: import.meta.dirname,
|
||||||
|
},
|
||||||
|
// other options...
|
||||||
|
},
|
||||||
|
},
|
||||||
|
])
|
||||||
|
```
|
||||||
|
|
||||||
|
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:
|
||||||
|
|
||||||
|
```js
|
||||||
|
// eslint.config.js
|
||||||
|
import reactX from 'eslint-plugin-react-x'
|
||||||
|
import reactDom from 'eslint-plugin-react-dom'
|
||||||
|
|
||||||
|
export default defineConfig([
|
||||||
|
globalIgnores(['dist']),
|
||||||
|
{
|
||||||
|
files: ['**/*.{ts,tsx}'],
|
||||||
|
extends: [
|
||||||
|
// Other configs...
|
||||||
|
// Enable lint rules for React
|
||||||
|
reactX.configs['recommended-typescript'],
|
||||||
|
// Enable lint rules for React DOM
|
||||||
|
reactDom.configs.recommended,
|
||||||
|
],
|
||||||
|
languageOptions: {
|
||||||
|
parserOptions: {
|
||||||
|
project: ['./tsconfig.node.json', './tsconfig.app.json'],
|
||||||
|
tsconfigRootDir: import.meta.dirname,
|
||||||
|
},
|
||||||
|
// other options...
|
||||||
|
},
|
||||||
|
},
|
||||||
|
])
|
||||||
|
```
