4. Landing Pages and Marketing Websites: Next.js enables developers to quickly create high-performance landing pages and marketing websites. Its automatic code splitting feature ensures that only necessary code is downloaded, resulting in faster loading times and better user experience.

5. Dashboards and Data Visualizations: Next.js can be used to build data-heavy applications, such as dashboards and data visualizations. Its flexibility and integration with libraries like D3.js and React-based charting libraries make it suitable for creating interactive and real-time data-driven interfaces.

6. Progressive Web Apps (PWAs): Next.js supports building Progressive Web Apps, which are web applications that provide an app-like experience with offline functionality, push notifications, and device hardware access. With Next.js, developers can create PWAs with server-side rendering and optimized performance.

7. SaaS Applications: Next.js can be utilized to build software-as-a-service (SaaS) applications, where multiple users access the application over the web. Its server-side rendering and API routes make it easy to create dynamic features, authentication systems, and handle user interactions.

8. Documentation Websites: Next.js’s simplicity and support for static site generation make it an excellent choice for building documentation websites. Developers can easily generate and maintain documentation pages, and users benefit from fast loading times and easy navigation.

9. Portfolio Websites: Next.js can be used to create impressive portfolio websites for showcasing projects and skills. Its performance optimizations and support for CSS-in-JS libraries make it a great choice for creating visually appealing and interactive portfolios.

These examples demonstrate the versatility of Next.js as a framework for building various types of web applications. Whether it’s a dynamic web app, content-driven website, e-commerce platform, or data visualization tool, Next.js provides the necessary tools and optimizations to deliver high-quality and performant web experiences.

Key Features of Next.js

Server-side Rendering (SSR)

One of the standout features of Next.js is its built-in support for server-side rendering. SSR enables rendering React components on the server before sending them to the client, resulting in faster initial page loads and improved search engine optimization (SEO). Next.js makes SSR effortless by providing a simple API and automatic code splitting, allowing developers to decide which parts of their application should be rendered on the server.

Static Site Generation (SSG)

In addition to SSR, Next.js also supports static site generation. With SSG, you can pre-render pages at build time and serve them as static HTML files. This approach is beneficial for content-driven websites, blogs, and landing pages that don’t require real-time data. SSG improves performance by reducing server load and ensuring faster delivery of static content to users.

Automatic Code Splitting

Next.js automatically splits your JavaScript code into smaller chunks based on the pages and components you use. This code splitting feature improves the initial loading time of your application by delivering only the necessary code to the client, avoiding unnecessary downloads. It also allows for better caching and enables efficient client-side routing.

API Routes

Next.js simplifies the creation of API endpoints by introducing API routes. With API routes, you can define serverless functions that handle HTTP requests and responses. This built-in API functionality eliminates the need for setting up a separate server and provides an easy way to create server-side logic within your Next.js application.

CSS-in-JS and CSS Modules

Styling is an essential aspect of web development, and Next.js offers flexible options for managing CSS. It supports popular CSS-in-JS libraries like styled-components and CSS Modules, allowing developers to write scoped CSS directly in their components. This approach promotes modularity and prevents CSS class name collisions.

Zero Configuration

Next.js embraces the concept of zero configuration. Out of the box, Next.js provides sensible defaults for most use cases, reducing the need for manual setup. It handles webpack configuration, routing, and other complex aspects, allowing developers to focus on building their application logic rather than spending time on boilerplate code.

Extensibility and Ecosystem

Next.js is highly extensible and integrates seamlessly with the React ecosystem. It supports the latest features of React, including hooks and context API. Additionally, Next.js has a thriving ecosystem of plugins and community-contributed packages that further enhance its capabilities. Whether you need internationalization, authentication, or performance optimization, there’s likely a Next.js package available to fulfill your requirements.

Cons of using Next.js

The number of Next benefits is huge and clearly outweighs its cons. However, let’s write them down to be as objective as it’s possible.

1. Development and management: The flexibility, given by Next, has its cost – continuous management. To make all desired changes properly, you will need a dedicated person with proper knowledge. The good news is that this person doesn’t have to be a developer.

2. Ongoing cost: since Next.js does not provide many built-in front pages, you have to create your own front-end, which will require changes from time to time. It means that you will have to pay a frontend developer to get the job done.

3. Lack of built-in state manager: so if you need a state manager in your app, you have to add Redux, MobX or something else.

4. Low on plug-ins: you cannot use much of easy-to-adapt plugins.

5. Learning Curve: While Next.js simplifies many aspects of web development, there is still a learning curve, especially for beginners. Developers need to understand React and its concepts before diving into Next.js. Additionally, familiarity with server-side rendering and static site generation can be beneficial.

6. Limited Flexibility: Next.js follows a specific project structure and conventions. While this helps in reducing configuration and boilerplate code, it may limit flexibility for developers who prefer more control over their project setup.

7. Performance Overhead: Although Next.js provides performance optimizations, such as code splitting and server-side rendering, improper usage or inefficient coding practices can still impact performance. Developers need to be mindful of best practices and optimizations to ensure optimal performance.

8. Server Deployment: Deploying Next.js applications may require specific server configurations or platforms compatible with server-side rendering. While Next.js offers deployment options through Vercel (formerly ZEIT Now) and other platforms, additional considerations and setup may be necessary for custom deployment environments.

9. Additional Complexity for Small Projects: For smaller projects with simple requirements, Next.js may introduce additional complexity. The benefits of server-side rendering and static site generation may not be fully utilized, leading to unnecessary complexity for such projects.
