What is Turbopack for NextJS?

Turbopack is an incremental bundler for JavaScript and TypeScript, created by the same team that makes Next.js. Think of it as a super-fast successor to Webpack, which has been the standard for many years.

What is a Bundler?

When you build a modern web app, you have many files (JavaScript, CSS, images, etc.). A bundler takes all these files and intelligently combines them into a few optimized files that a web browser can understand and load efficiently.

What Makes Turbopack Special?

Its main feature is speed. 🚀

It's built from the ground up using Rust, which allows it to be much faster than older bundlers like Webpack that are written in JavaScript. For a developer, this means:

• Faster Dev Server Startup: When you run npm run dev, your project will be ready to view in the browser much more quickly.

• Instant Updates: When you save a change in your code, the update appears on your screen almost instantly. This is often called Hot Module Replacement (HMR).

What is "use client" in NextJS?

"use client" a special instruction for Next.js. It declares this component as a "Client Component." This means the interactive parts of this code will run in the user's web browser, not on a server.
