🚨 Most Next.js Developers Are Using "use client" Wrong
When developers start using the Next.js App Router, one of the first things they do is add "use client" everywhere.
But here’s the problem 👇
Overusing "use client" can actually hurt your app's performance.
Why?
Because "use client" turns a component into a Client Component, which means it must ship JavaScript to the browser and run there.
That leads to:
❌ Larger JavaScript bundles
❌ More hydration work in the browser
❌ Slower page load performance
❌ Losing the benefits of Server Components
So what’s the better approach?
👉 Keep most components as Server Components
👉 Use "use client" only when you truly need it
For example, when using:
• React hooks (useState, useEffect)
• Event handlers (onClick, onChange)
• Browser APIs (window, localStorage)
• Interactive libraries
Best practice:
Make the page server-rendered and isolate only the interactive parts as client components.
The result?
⚡ Smaller bundles
⚡ Faster performance
⚡ Better scalability
Sometimes the best optimization is simply removing "use client" where it isn’t needed.
