    • Automatic code splitting for faster initial load times.
    • Integrated routing and dynamic imports.

    Installation and Setup

    To get started, you can easily set up a new Next.js project using the following command in your terminal:

    npx create-next-app my-next-app

    This command initializes a new Next.js application with all the necessary configurations.

    Creating Your First Next.js Project

    Once your environment is ready, you can create components and pages, leveraging the framework’s built-in functionalities, such as routing and CSS. Start by creating a simple component inside the pages directory, and access it via your browser at http://localhost:3000/.

    Module 2: Next.js Fundamentals

    Pages and Routing

    The routing in Next.js is incredibly straightforward due to its file-based approach. For every component in the pages directory, a corresponding route is created. For instance, a file called about.js in the pages folder will be accessible at /about.

    Dynamic Routing

    Next.js allows for dynamic routing through the use of brackets within file names, such as [id].js. This enables you to create pages that can handle dynamic content based on the route parameters.

    Building Layouts with Next.js

    Layouts are essential for maintaining a consistent structure across your application. You can create a wrapper component that includes your navigation, footer, and other shared elements.

    Handling Static and Dynamic Content

    With the flexibility to combine static and dynamic content seamlessly, Next.js facilitates effective content delivery without sacrificing performance.

    Module 3: Server-Side Rendering (SSR) and Static Site Generation (SSG)

    SSR vs. SSG: When and Why to Use Them

    Understanding when to choose SSR or SSG is crucial. SSR is beneficial for pages that need to render fresh data on each request, while SSG is ideal for content that does not change frequently, offering faster load times. A strategic choice between the two can significantly enhance your application’s performance and SEO.

    Implementing SSR in Your Next.js Project

    To implement SSR, you can use the getServerSideProps function, which fetches data for a page at request time, delivering content tailored to each user.

    Generating Static Sites with Next.js

    Static Site Generation, achieved with getStaticProps, pre-renders pages at build time. This approach is optimal for performance and scalability, generating static HTML that can be served instantly.
