Key updates in Next.js 14

Vercel calls Next.js 14 their “most focused release.” What does this mean for you? Instead of adding new features, the Next.js team has made their existing tools better. Guillermo Rauch, who started Next.js and is the CEO of Vercel, proudly announced that Next.js 14 doesn’t have any new APIs.

Boosting Performance

The main goal has been to speed things up. The team has improved Turbopack, their compiler built with Rust. This has made the local server on vercel.com start 53% faster and refresh up to 94% quicker when code changes are made. However, remember that Turbo isn’t fully ready yet. To see how it’s doing, there’s a website called “Are we Turbo Yet?” where you can check out how well it’s performing in tests.

Stable Server Actions

They also worked on making things easier. They’ve introduced an experimental feature known as “Partial Pre-rendering.” You might ask, “What’s different about this from other rendering methods we know?” It’s still being tested, but you can try it by turning it on in your configuration file. The goal is to make Next.js simpler for developers.

By using what’s called Suspense component boundaries, the system can tell which parts of your app change and which stay the same. It prepares the parts that don’t change as HTML and only updates the parts that do change when necessary. This blends the best aspects of both static and dynamic rendering methods.
