Next Js Bangla Tutorial: Data Fetching, Server-Side Rendering, Static Site Generation | Part 3

Welcome to part 3 of our Next Js Bangla tutorial series. In this tutorial, we will be focusing on data fetching, server-side rendering, and static site generation in Next Js. These are important concepts to understand when working with Next Js, so let’s dive in!

Data Fetching

Data fetching in Next Js allows you to fetch data from an API or any other source and use that data to render your components. This can be done using the `getStaticProps` or `getServerSideProps` functions in Next Js. These functions allow you to fetch data at build time or request time, depending on your needs.

Server-Side Rendering

Server-side rendering in Next Js allows you to pre-render your pages on the server and serve them to the client as fully-rendered HTML. This can lead to faster initial page loads and improved SEO. With Next Js, server-side rendering can be achieved using the `getServerSideProps` function. This function is used to fetch data at request time and pass it to the page component for rendering.

Static Site Generation

Static site generation in Next Js allows you to pre-build your entire website as static files that can be served to the client. This can result in extremely fast page loads and improved performance. In Next Js, static site generation is achieved using the `getStaticProps` function. This function is used to fetch data at build time and pre-render the pages as static files.

With these concepts in mind, you can build powerful and performant web applications using Next Js. We hope this tutorial has helped you understand data fetching, server-side rendering, and static site generation in Next Js.
