+# Route Handler / API Routes
+
+- Use Route Handlers when data fetching from Client Components
+- To create API routes (route.ts), always use the `enhanceRouteHandler` function from the "@kit/supabase/routes" package. [index.ts](mdc:packages/next/src/routes/index.ts)
+
+```tsx
+import { z } from 'zod';
+import { enhanceRouteHandler } from '@kit/next/routes';
+import { NextResponse } from 'next/server';
+
+const ZodSchema = z.object({
+  email: z.string().email(),
+  password: z.string().min(6),
+});
+
+export const POST = enhanceRouteHandler(
+  async function({ body, user, request }) {
+    // 1. "body" is already a valid ZodSchema and it's safe to use
+    // 2. "user" is the authenticated user
+    // 3. "request" is NextRequest
+    // ... your code here
+    return NextResponse.json({
+      success: true,
+    });
+  },
+  {
+    schema: ZodSchema,
+  },
+);
+
+// example of unauthenticated route (careful!)
+export const GET = enhanceRouteHandler(
+  async function({ user, request }) {
+    // 1. "user" is null, as "auth" is false and we don't require authentication
+    // 2. "request" is NextRequest
+    // ... your code here
+    return NextResponse.json({
+      success: true,
+    });
+  },
+  {
+    auth: false,
+  },
+);
+```
