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 uses Oxc
• @vitejs/plugin-react-swc uses SWC

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.

Expanding the ESLint configuration

If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:

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 and eslint-plugin-react-dom for React-specific lint rules:

// 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...
    },
  },
])

// Before onChange={e => setPoFile(e.target.files[0])}

// After onChange={(e: React.ChangeEvent) => { if (e.target.files) setPoFile(e.target.files[0]); }}

**4. Install and run**

npm install npm run dev

If TypeScript still flags anything, run the type checker directly to see the full list:

npx tsc --noEmit

**5. Push to GitHub and deploy to Vercel**

Identical to the JS steps — Vercel auto-detects TypeScript Vite projects with no extra config needed:

git init git add . git commit -m "initial commit" git remote add origin https://github.com/YOUR_USERNAME/little-passports-school.git git branch -M main git push -u origin main

6. Deploy to Vercel

Go to vercel.com and sign up (free) — sign in with your GitHub account Click "Add New Project" Import your little-passports-school repository Vercel will auto-detect it as a Vite project — leave all settings as default Click Deploy
