> Optimizing Next.js Applications for Production

Next.js provides powerful features for building performant web applications, but knowing how to leverage them effectively is crucial for production success.

Static Generation vs Server-Side Rendering

Choose the right rendering strategy for each page. Static generation (SSG) provides the best performance for content that changes infrequently:

export async function generateStaticParams() {
  const posts = await fetchPosts()
  return posts.map((post) => ({
    slug: post.slug,
  }))
}

export default async function BlogPost({ params }: Props) {
  const post = await fetchPost(params.slug)
  return <Article post={post} />
}

Image Optimization

Always use the Next.js Image component for automatic optimization, lazy loading, and responsive images.
