Setting Up Your Next.js 15 Project
Prerequisites
Before you start, ensure you have the following installed on your machine:

You can now access your application at http://localhost:3000
in your web browser.
Step 4: Exploring the Project Structure
Next.js has a well-defined project structure. Here are some of the key folders and files you’ll encounter:
- pages/: This folder contains your application’s pages. Each file in this directory corresponds to a route based on its filename.
- public/: Static files like images and fonts can be placed here for easy access.
- styles/: This folder is where you can add your global CSS styles or specific component styles.
Step 5: Creating Your First Page
To create a new page, simply add a new file in the pages
directory. For example, create a file called about.js
:
