+description: Vite 8 Rolldown bundler and Oxc transformer migration
+---
+
+# Rolldown Migration (Vite 8)
+
+Vite 8 replaces esbuild+Rollup with Rolldown, a unified Rust-based bundler.
+
+## What Changed
+
+| Before (Vite 7) | After (Vite 8) |
+|-----------------|----------------|
+| esbuild (dev transform) | Oxc Transformer |
+| esbuild (dep pre-bundling) | Rolldown |
+| Rollup (production build) | Rolldown |
+| `rollupOptions` | `rolldownOptions` |
+| `esbuild` option | `oxc` option |
+
+## Performance Impact
+
+- 10-30x faster than Rollup for production builds
+- Matches esbuild's dev performance
+- Unified behavior between dev and build
+
+## Config Migration
+
+### rollupOptions → rolldownOptions
+
+```ts
+// Before (Vite 7)
+export default defineConfig({
+  build: {
+    rollupOptions: {
+      external: ['vue'],
+      output: { globals: { vue: 'Vue' } },
+    },
+  },
+})
+
+// After (Vite 8)
+export default defineConfig({
+  build: {
+    rolldownOptions: {
+      external: ['vue'],
+      output: { globals: { vue: 'Vue' } },
+    },
+  },
+})
+```
+
+### esbuild → oxc
+
+```ts
+// Before (Vite 7)
+export default defineConfig({
+  esbuild: {
+    jsxFactory: 'h',
+    jsxFragment: 'Fragment',
+  },
+})
+
+// After (Vite 8)
+export default defineConfig({
+  oxc: {
+    jsx: {
+      runtime: 'classic',
+      pragma: 'h',
+      pragmaFrag: 'Fragment',
+    },
+  },
+})
+```
+
+### JSX Configuration
+
+```ts
+export default defineConfig({
+  oxc: {
+    jsx: {
+      runtime: 'automatic',  // or 'classic'
+      importSource: 'react', // for automatic runtime
+    },
+    jsxInject: `import React from 'react'`,  // auto-inject
+  },
+})
+```
+
+### Custom Transform Targets
+
+```ts
+export default defineConfig({
+  oxc: {
+    include: ['**/*.ts', '**/*.tsx'],
+    exclude: ['node_modules/**'],
+  },
+})
+```
+
+## Plugin Compatibility
+
+Most Vite plugins work unchanged. Rolldown supports Rollup's plugin API.
+
+If a plugin only works during build:
+
+```ts
+{
+  ...rollupPlugin(),
+  enforce: 'post',
+  apply: 'build',
+}
+```
+
+## New Capabilities
+
+Rolldown unlocks features not possible before:
+
+- Full bundle mode (experimental)
+- Module-level persistent cache
+- More flexible chunk splitting
+- Module Federation support
+
+## Gradual Migration
+
+For large projects, migrate via `rolldown-vite` first:
+
+```bash
+# Step 1: Test with rolldown-vite
+pnpm add -D rolldown-vite
+
+# Replace vite import in config
+import { defineConfig } from 'rolldown-vite'
+
+# Step 2: Once stable, upgrade to Vite 8
+pnpm add -D vite@8
+```
+
+## Overriding Vite in Frameworks
+
+When framework depends on older Vite:
+
+```json
+{
+  "pnpm": {
+    "overrides": {
+      "vite": "8.0.0"
+    }
+  }
+}
+```
