Code Splitting

Code splitting is the process of dividing your code into smaller bundles, which are only loaded when needed. This can significantly improve page load times, especially for large applications.
Next.js automatically splits your code into bundles based on the routes in your application. For example, if you have a route for the homepage and a route for a blog post, Next.js will create two bundles: one for the homepage and one for the blog post.
When a user visits a page, Next.js only loads the bundle that contains the code for that page. This can significantly improve page load times, especially for users who are visiting pages that are deep within your application.

Client-side Routing

Next.js provides a simple and intuitive way to manage routing in your application. You can create routes as files in the pages directory and use the built-in Link component to link between them.
The Link component takes a href prop, which specifies the route that you want to navigate to. When a user clicks on a Link component, Next.js will load the specified route.
Next.js also provides a number of other features for managing routing, such as nested routing and dynamic routing.

Pre-rendering

Next.js can pre-render your pages at build time or on demand. Pre-rendering involves generating the HTML for your pages before they are served to the user. This can improve performance and SEO.
Next.js offers two forms of pre-rendering:

• 1.Static generation: Static generation generates the HTML for your pages at build time. The pre-rendered HTML is then reused on each request.
• 2.Server-side rendering: Server-side rendering generates the HTML for your pages on demand. This can be slower than static generation, but it allows you to render pages with dynamic content.

Next.js lets you choose which pre-rendering method to use for each page. You can create a “hybrid” Next.js app using static generation for most pages and using server-side rendering for others.

API Routes

Next.js lets you easily create API endpoints as Node.js serverless functions. This can be useful for building microservices or for providing data to your front-end application.
To create an API route, simply create a function in the app/api directory. The function can then be accessed using the /api/ URL.
Next.js provides a number of built-in features for API routes, such as authentication and authorization.

Full Extensibility

Next.js is fully extensible, so you can add your own custom features and functionality. This can be done by creating plugins or by extending the Next.js core.
There are a number of existing plugins and extensions available for Next.js. These plugins can add a variety of features to your application, such as support for authentication, authorization, and internationalization.
If you need to add a custom feature to your Next.js application that is not already available as a plugin, you can create your own plugin or extend the Next.js core.
With Next.js, developers can build websites that feel fast and smooth, giving visitors a great experience. It's used by a big community of creative minds who make all kinds of websites, from blogs to online stores. They love it because it saves them time and lets them focus on making their websites unique and special. So, whether you're a seasoned developer or just starting out, Next.js is here to make your web-building journey exciting and successful.

Next.js vs Vue

• 1.Performance: Next.js has a performance advantage over Vue due to its support for server-side rendering (SSR) and static site generation (SSG).
• 2.Features: Next.js has a number of features that are not available in Vue, such as automatic routing, built-in SEO support, and support for serverless functions.
• 3.Ecosystem: Next.js has a larger and more active ecosystem than Vue, which means that there are more resources available to help you develop your application.

Next.js vs Angular

• 1.Performance: Next.js and Angular have similar performance characteristics, but Next.js has a slight advantage due to its support for SSR and SSG.
• 2.Features: Next.js and Angular are both full-featured JavaScript frameworks, but Next.js is more focused on performance and SEO.
• 3.Ecosystem: Next.js has a larger and more active ecosystem than Angular, which means that there are more resources available to help you develop your application.

Next.js vs Go

• 1.Performance: Next.js can achieve good performance with SSR and SSG, even though it is a JavaScript framework. This is because Next.js uses a number of techniques to optimize the performance of your application, such as code splitting and caching.
• 2.Ease of use: Next.js is a JavaScript framework, so it is easier to learn and use than Go. This is especially beneficial for developers who are already familiar with React.
• 3.Ecosystem: Next.js has a large and active ecosystem of resources. This means that there are many tutorials, documentation, and third-party libraries available to help you develop your application.

Next.js vs Ruby on Rails

• 1.Performance: Next.js can achieve better performance than Ruby on Rails, especially for pages that are not frequently updated. This is because Next.js uses SSR and SSG to pre-render the HTML of your pages.
• 2.SEO: Next.js's SSR and SSG features can also improve the SEO of your application. This is because Google and other search engines can index your static pages even if they are not updated frequently.
• 3.Ease of use: Next.js is easier to learn and use than Ruby on Rails, especially for developers who are already familiar with React.
• 4.Ecosystem: Next.js has a large and active ecosystem of resources. This means that many tutorials, documentation, and third-party libraries are available to help you develop your application.
