Reduce Client JavaScript
One of the most powerful performance strategies in modern Next.js is avoiding unnecessary client-side JavaScript.
Every Client Component creates a client boundary. Large libraries imported into those components can increase the browser bundle.
Keep static and data-heavy UI on the server. Move only genuinely interactive pieces to the client.
Key Takeaways
- Server Components can reduce browser JavaScript.
- Audit large dependencies imported into Client Components.
- Small client boundaries are generally easier to optimize.
