To create a new Next.js project, run

npx create-next-app@latest

You’ll be prompted with a few questions. These are to know what kind of things you need, like

• the name of your project, say, nextjs-15
• whether or not you want to use typescript—I'll go with yes.
• Since tailwind is a popular styling option these days, let's choose yes
• It will ask if you want to organize your code inside a src/ folder. I usually don't use it, but this is more of a preference than a feature.
• About the app router, say yes here, as it's a key feature of Next.js. Otherwise, 99% of the features will not work. You’ll get pages router instead.
• Regarding turbopack, choose yes. It's a next-generation bundler written in Rust, designed as a successor to Webpack. It offers faster startup, quicker updates, and improved memory efficiency.
• Next, you'll be asked if you want to customize the import alias from @/*. I prefer to keep it as is, so I'll say no.

And that's it, you're done!

Next.js will now install all the necessary dependencies, and within a few seconds, your project will be ready to go.
