+# Next.js 15 Migration & Configuration Guide
+
+## Upgrading to Next.js 15
+
+```bash
+npx @next/codemod@canary upgrade latest
+# or manual:
+npm install next@latest react@latest react-dom@latest
+```
+
+## Key Breaking Changes (14 → 15)
+
+### 1. Async Request APIs (Breaking)
+`cookies()`, `headers()`, `params`, `searchParams` are now async:
+
+```tsx
+// Before (Next.js 14)
+export default function Page({ params }) {
+  const { id } = params
+}
+
+// After (Next.js 15)
+export default async function Page({ params }) {
+  const { id } = await params
+}
+
+// cookies and headers
+import { cookies, headers } from "next/headers"
+const cookieStore = await cookies()
+const headersList = await headers()
+```
+
+### 2. Caching Defaults Changed
+`fetch()` no longer caches by default (was `force-cache`, now `no-store`).
+Add `{ cache: "force-cache" }` or set route-level `export const fetchCache = "default-cache"` to restore.
+
+### 3. React 19 Compatibility
+Next.js 15 supports React 19. New hooks available:
+- `useActionState` (replaces `useFormState`)
+- `useFormStatus`
+- `use()` for reading promises/context
+
+## next.config.ts (TypeScript config)
+
+```ts
+import type { NextConfig } from "next"
+
+const config: NextConfig = {
+  experimental: {
+    ppr: "incremental",        // Partial Prerendering
+    reactCompiler: true,       // React Compiler (auto-memoization)
+  },
+  images: {
+    remotePatterns: [
+      { protocol: "https", hostname: "images.example.com" },
+    ],
+  },
+  logging: {
+    fetches: { fullUrl: true }, // Log all fetch calls in dev
+  },
+}
+
+export default config
+```
+
+## Environment Variables
+
+```bash
+# .env.local
+DATABASE_URL="postgresql://..."
+NEXT_PUBLIC_API_URL="https://api.example.com"  # exposed to browser
+```
+
+```ts
+// Access server-side
+process.env.DATABASE_URL
+
+// Access client-side (only NEXT_PUBLIC_ prefix)
+process.env.NEXT_PUBLIC_API_URL
+```
+
+## Turbopack (Default in Dev)
+
+```bash
+next dev              # uses Turbopack by default in Next.js 15
+next dev --turbopack  # explicit flag (same behavior)
+next build            # Webpack still default for production builds
+```
+
+## TypeScript Path Aliases
+
+```json
+// tsconfig.json
+{
+  "compilerOptions": {
+    "baseUrl": ".",
+    "paths": {
+      "@/*": ["./*"],
+      "@/components/*": ["./components/*"],
+      "@/lib/*": ["./lib/*"]
+    }
+  }
+}
+```
