Setting up a Next.js project involves a few simple steps. First, you'll need to have Node.js installed on your computer. Once Node.js is installed, you can use the Node Package Manager (npm) to create a new Next.js project. To do this, open a terminal window and run the following command:
1
|
npx create-next-app
|
This will create a new Next.js project in a directory of your choice. Once the project is created, you can navigate into the project directory and start the development server by running the following command:
1
|
npm run dev
|
This will start the Next.js development server, allowing you to view your project in a web browser. From there, you can start building your project using the Next.js framework and React components. That's all there is to setting up a Next.js project!
