How to check the Next.js version in your current project

1. Check the package.json file:

Open the package.json file and look for the Next.js version under the dependencies section. You can also use the following command in the terminal to view the contents of the package.json file.

cat package.json

Example:

{
  "dependencies": {
    "next": "^12.0.7",
    "react": "^17.0.2",
    "react-dom": "^17.0.2"
  }
}

2. Use the npm list command:

Run the following command in the terminal to check the installed Next.js version.

npm list next

If you're using yarn, use this command instead:

yarn list next

This will display the Next.js version currently used in your project.
