Next.js 14 Crash Course – Bangla Tutorial for Next.js 2024

Introduction:
Next.js is a versatile JavaScript framework that allows you to build server-rendered React applications easily. In this crash course, we will cover the basics of Next.js version 14 and explore its features. This tutorial is ideal for beginners looking to get started with Next.js and build their first application.

Prerequisites:
Before starting this tutorial, you should have a basic understanding of JavaScript and React. You should also have Node.js and npm installed on your machine.

Step 1: Setting up a new Next.js project
To get started with Next.js, you can create a new project using the following command:

npx create-next-app my-next-app
cd my-next-app

This command will create a new Next.js project in a directory named my-next-app. Once the project is created, you can navigate to the project directory using cd my-next-app.

Step 2: Running the Next.js project
You can run your Next.js project by running the following command:

npm run dev

This command starts the development server for your Next.js project. You can then access your project in a web browser by visiting http://localhost:3000.

Step 3: Understanding the project structure
Next.js projects have a specific folder structure that you should be aware of:

• pages: This folder contains all the pages of your Next.js application. Each file in this folder represents a different route in your application.
• public: This folder contains static assets like images, stylesheets, and fonts.
• components: This folder contains reusable React components that you can use in your pages.
• styles: This folder contains CSS stylesheets for your application.

Step 4: Creating your first page
To create a new page in your Next.js application, you can create a new file in the pages folder. For example, you can create a file named index.js with the following content:

import React from 'react';
const Home = () => {
  return (
    <div>
      <h1>Welcome to Next.js</h1>
    </div>
  );
};
export default Home;

This code defines a simple React component that displays a heading on the page. You can then access this page in your browser by visiting http://localhost:3000.

Step 5: Adding navigation to your Next.js application
Next.js provides a built-in Link component that you can use for navigation between pages. For example, you can update your index.js file to include a link to another page:

import React from 'react';
import Link from 'next/link';
const Home = () => {
  return (
    <div>
      <h1>Welcome to Next.js</h1>
      <Link href="/about">
        <a>About</a>
      </Link>
    </div>
  );
};
export default Home;

In this code, we have added a Link component that links to the /about page in your application.

Step 6: Deploying your Next.js application
Once you have finished developing your Next.js application, you can deploy it to a hosting provider like Vercel or Netlify. These hosting providers offer seamless integration with Next.js and make it easy to deploy your application.

To deploy your Next.js application, you can run the following command:

npm run build
npm run start

This command builds your Next.js application and starts a production server. You can then access your deployed application using the provided URL.

Conclusion:
In this crash course, we covered the basics of Next.js 14 and learned how to create a new Next.js project, create pages, add navigation, and deploy the application. Next.js is a powerful framework that makes it easy to build server-rendered React applications, and we hope this tutorial has helped you get started with Next.js. Happy coding!
