Dynamic Imports for Heavy Components
Use next/dynamic to lazy-load large components not needed on initial render.
Incorrect (Monaco bundles with main chunk ~300KB):
import { MonacoEditor } from './monaco-editor'
function CodePanel({ code }: { code: string }) {
return <MonacoEditor value={code} />
}
Correct (Monaco loads on demand):
import dynamic from 'next/dynamic'
const MonacoEditor = dynamic(
() => import('./monaco-editor').then(m => m.MonacoEditor),
{ ssr: false }
)
function CodePanel({ code }: { code: string }) {
return <MonacoEditor value={code} />
}
