Getting Started with Next.js 14
Next.js 14 brings exciting new features that make building web applications faster and more efficient than ever before.
What's New in Next.js 14
Server Actions (Stable)
Server Actions allow you to run server-side code directly from your components. This eliminates the need for separate API routes for many use cases.
'use server'
async function createPost(formData: FormData) {
const title = formData.get('title')
// Save to database
await db.post.create({ data: { title } })
revalidatePath('/posts')
}
Partial Prerendering (Preview)
Partial Prerendering is a new rendering model that allows you to combine static and dynamic content in the same route.
Improved Metadata API
The metadata API has been improved with better TypeScript support and new options for controlling how your pages appear in search results and social media.
Setting Up Your Project
To create a new Next.js 14 project, run:
npx create-next-app@latest my-app
Follow the prompts to configure TypeScript, ESLint, Tailwind CSS, and the App Router.
App Router Best Practices
- Use Server Components by default - Only add 'use client' when needed
- Leverage caching - Understand the different caching mechanisms
- Optimize images - Always use the next/image component
- Handle loading states - Use loading.tsx files for streaming
Conclusion
Next.js 14 is a significant release that makes it easier than ever to build production-ready web applications. The stable Server Actions, improved performance, and developer experience improvements make it a great choice for your next project.
