Prerequisites

Before we begin, make sure you have basic knowledge of JavaScript and React. If you’re new to React, consider going through the official React tutorial first.

Creating a Simple Blog App

Let’s create a basic blog app using Next.js. Follow these steps:

1. Initialize a New Next.js App:

   • Open your terminal and run the following command:

     
     
     npx create-next-app my-blog
     

2. **Navigate to Your Project Directory**:
     - navigate to the folder created by the previous command

    ```


    cd my-blog

1. Start the Development Server:

   • to run local dev server

   
   
   npm run dev
   

4. **Create a New Page**:
    - under the `app`, create a new directory called `blog` and add new file `page.js`.
    - Add the following content to `page.js`:

        ```jsx


        /blog/page.js
        const Blog = () => {
          return <div>Welcome to my blog!</div>;
        };

        export default Blog;

1. View Your App:
   • Open your browser and visit http://localhost:3000.
   • You’ll see the “Welcome to my blog!” message when you visit /blog.
2. Add More Pages:
   • Create additional pages (e.g., about.js, contact.js) under about and contact directory.
   • Each page should export a React component.
   • More information about how pages and layouts works
3. Styling:
   • Next.js supports CSS modules, so you can create a styles.module.css file in your component folder.
   • Import styles into your components and apply them as needed.
