You can also check the version of your nextjs apart from the first method directly at the command line. For my readers that love command line this is for you.

1. Open Terminal or Command Prompt:

• Go to your project directory using cd path/to/your/project.

1. Run the Version Command:

• You are required to run the following command:
  npx next --version
• If you don’t like the first one , you can use this one:
  npm list next
  This command will return the version of Next.js installed in your project.

• Move into the node_modules directory inside your project’s root folder.

1. Find the next Folder:

1. Open the Nextjs package.json:

• Open the next directory.
• Open package.json.
• Scroll to the "version" field.

If your Next.js application is running in development mode, check the version via the browser console.

1. Open Your Application in a Browser:
   Run a Next.js app by using npm run dev or yarn dev, open it in a web browser.
2. Open the Browser Console:

• Right-click on the page and choose “Inspect” or use the shortcut key combination Ctrl+Shift+I (Windows) or Cmd+Option+I (Mac) to open DevTools.

   Inside the console, add __NEXT_DATA__.buildId and press Enter.

If you are to create a new Next.js project, then followed thus method though I don’t recommend it. Then at the project creation step you can see the version explicitly as shown below:

1. Run npx create-next-app:

• Run npx create-next-app@latest to create a new project using the latest version.
• You can also use a specific version by running something like npx create-next-app@12.1.0. though it depends what you want it what someone recommend you to do
