Next JS React Framework for Building Fast Websites

Next.js is a popular React framework for building fast and efficient websites. It's known for its server-side rendering capabilities.

One of the key benefits of Next.js is its ability to pre-render pages at build time, which can significantly improve page load times. This is especially useful for large websites with many pages.

With Next.js, you can also use its built-in internationalization (i18n) features to easily support multiple languages on your website.

Run the following command to build the project files:

That's it! You now have a basic Next.js project set up and ready to go.

In Next.js, routing is a crucial aspect of building a React application, and it's essential to understand how it works.

To get the current route in Next.js, you can use a specific method, but unfortunately, that information is not provided in the article section. However, you can catch all routes in Next.js using a particular approach, which is more like a workaround than a straightforward solution.

Here are some key aspects of routing in Next.js:

In Next.js, you can use server-side rendering to fetch data and render pages on the server. This is achieved through the getServerSideProps() function.

The getServerSideProps() function is a powerful tool that allows you to pre-render pages at build time, but also fetch data on the server-side for each request. This is particularly useful for pages that require dynamic data.

To handle dynamic routes, you can use the getStaticPaths() function. This function generates the paths for static pages at build time.

Next.js also provides a way to generate image metadata using the generateImageMetadata function. This function is useful for optimizing images and reducing page load times.

Fetch is another key function in Next.js that allows you to make HTTP requests to external APIs or services. This function is useful for retrieving data from external sources.

Here are some key functions in Next.js that you should know about:

Routing is a crucial aspect of building a Next.js application. You can get the current route in NextJS using the `useRouter` hook.

Next.js provides a built-in way to create your own APIs, called API routes. With API routes, you can create your own endpoints and handle incoming requests however you want. This is useful for creating a custom backend for your Next.js application or exposing data from your database to the front end.

To catch all routes in NextJS, you can create a new file at the following location: `src/app/api/admin/[...slug]/route.ts` for the App Router and `src/pages/api/admin/[[...slug]].ts` for the Pages Router.

Next.js's routing system is helpful, but it comes at a cost. By tightly coupling your routing logic to your pages, you make your pages heavier and more difficult to maintain.

To create a new page in the Next.js app, you can create a new file at the following location: `src/app/admin/page.tsx` for the App Router and `src/pages/admin/index.tsx` for the Pages Router.

Here is a list of ways to create routes in Next.js:

Components are a fundamental part of building web applications, and Next.js provides several features to make working with components easier.

Next.js uses React, which has its own set of features that make building components a breeze. React's JavaScript Syntax Extension (JSX) allows you to write HTML-like code in your JavaScript files, making it easy to create reusable components.

One of the key features of React is its Virtual DOM, which improves performance by only updating the parts of the DOM that need to be changed. This is especially useful when building complex web applications.

In Next.js, components can be created as separate files, and the framework will automatically handle the routing for you. This is thanks to Next.js' file system routing feature.

Here are some of the key features of React components:

These features, combined with Next.js' own features, make building web applications a much more efficient and enjoyable process.

Flowbite components are a great way to create reusable UI elements. You can import them from flowbite-react to use in your app.

To use Flowbite components, you can import them from flowbite-react. This makes it easy to add UI elements to your app.

Flowbite components can be used to create custom alerts and other UI elements. This helps to make your app more interactive and engaging.

React is a powerful JavaScript library that enables developers to create reusable UI elements, including Flowbite components. This makes it easy to build your app from small, reusable pieces.

Next.js provides a built-in way to create your own APIs, called API routes, which give you a lot of flexibility in how you build your Next.js application.

API routes can be used to create a custom backend for your Next.js application or to expose data from your database to the front end.

To use API routes, you can create your own endpoints and handle incoming requests however you want.

You can use API routes to fetch and update data, as shown in Example 2, where the react-admin data provider is updated to use the Supabase adapter.

API routes are a powerful tool for building custom backends and exposing data to the front end.

Supabase provides a PostgREST endpoint, which is used with the ra-data-postgrest adapter to fetch and update data in the react-admin app.

This setup allows for a seamless data flow between the front end and the back end.

JSX is a combination of JavaScript and HTML, used to create React elements. This syntax extension makes writing HTML in React much easier, eliminating the need to call React.createElement(component, props, ...children) every time.

Writing HTML directly in React can be quite a pain, but JSX simplifies this process by allowing you to write HTML as you're most familiar with it. Babel then transpiles the code to JavaScript during runtime, making it work seamlessly.

The Virtual DOM is a concept created by the React team to improve rendering performance.

It's essentially a second instance of the actual DOM, created with JavaScript, which is much faster than the browser's DOM.

This virtual DOM makes a comparison between itself and a new virtual DOM whenever a state change occurs.

If the two DOMs are equal, the actual DOM remains untouched.

The actual DOM only gets updated when the virtual DOM detects a difference between the two instances.

This approach significantly reduces the number of DOM manipulations, making the application more efficient.

Automatic code splitting is a game-changer for Next.js applications. As your app grows, the size of third-party libraries, CSS, and JavaScript files increases, making page loads slower.

This is especially true for large files that need to be downloaded on page load. Next.js solves this issue by automatically splitting code into smaller units.

With automatic code splitting, scripts are only downloaded when required, significantly improving performance. This means users get a faster experience, and your app's load times are reduced.

As a result, users are more likely to stay engaged, and your app's overall performance improves.
