# Vite Configuration Skill

Patterns for configuring Vite projects.

## Basic Configuration

### Minimal Config

```typescript
// vite.config.ts
import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react'

export default defineConfig({
  plugins: [react()],
})
```

### Full Configuration

```typescript
// vite.config.ts
import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react'
import path from 'path'

export default defineConfig({
  plugins: [react()],

  // Root directory
  root: process.cwd(),

  // Base public path
  base: '/',

  // Public assets directory
  publicDir: 'public',

  // Cache directory
  cacheDir: 'node_modules/.vite',

  // Environment variables prefix
  envPrefix: 'VITE_',

  // Resolve options
  resolve: {
    alias: {
      '@': path.resolve(__dirname, './src'),
      '@components': path.resolve(__dirname, './src/components'),
      '@utils': path.resolve(__dirname, './src/utils'),
    },
    extensions: ['.mjs', '.js', '.ts', '.jsx', '.tsx', '.json'],
  },

  // CSS options
  css: {
    modules: {
      localsConvention: 'camelCase',
    },
    preprocessorOptions: {
      scss: {
        additionalData: `@import "@/styles/variables.scss";`,
      },
    },
  },

  // JSON options
  json: {
    namedExports: true,
    stringify: false,
  },

  // esbuild options
  esbuild: {
    jsxFactory: 'React.createElement',
    jsxFragment: 'React.Fragment',
    jsxInject: `import React from 'react'`,
  },
})
```

## Server Configuration

### Dev Server

```typescript
export default defineConfig({
  server: {
    host: 'localhost',
    port: 3000,
    strictPort: true,  // Fail if port is in use
    open: true,        // Open browser on start

    // HTTPS
    https: {
      key: fs.readFileSync('key.pem'),
      cert: fs.readFileSync('cert.pem'),
    },

    // Proxy configuration
    proxy: {
      '/api': {
        target: 'http://localhost:8080',
        changeOrigin: true,
        rewrite: (path) => path.replace(
