Next.js · Senior · Question 65 of 75

Why shouldn't a server component `fetch` your own Route Handler (`/api/products`) for data?

✓Correct answer: It adds an extra HTTP round trip, and prerendering at build time fails because no server is listening
2Route Handlers can't return JSON
3Server components can't use fetch

Explanation

Call the data source or a shared data-access function directly. Route Handlers are for external clients: mobile apps, webhooks, third parties.
