Running the Development Server

After creating a Next.js project, you need a way to run and preview your application locally. This is done using the development server.

The development server allows you to see your app in the browser and automatically updates the page when you make changes. This makes the development process fast and interactive.

Start the Development Server

To run your Next.js app, use the following command:

npm run dev

After running this command, open your browser and go to:

http://localhost:3000

You will see your application running.

What Happens Behind the Scenes

When you start the development server:

• Your app is compiled automatically;
• Changes in your code are reflected instantly;
• The page reloads or updates without manual refresh;
• Errors are displayed directly in the browser.
