Nest JS vs. Next JS: Which is Best For Server-side Applications?

 In the world of web development, choosing the right framework for your project can be a daunting task. There are countless options available, each with their own unique set of features and capabilities. Two popular choices for building server-side applications are Nest JS and Next JS.

Both Nest JS and Next JS are open-source JavaScript frameworks that can be used to build server-side applications. They are both built on top of popular technologies such as Node.js and React, and offer a wide range of features to help developers create high-quality, scalable applications.

In this blog post, we will take a deep dive into Nest JS and Next JS, comparing their features, capabilities, and use cases to help you decide which one is the best choice for your server-side application.


What is Nest JS?

Nest JS is a framework for building scalable server-side applications using Node.js and TypeScript. It was created by Kamil Myƛliwiec in 2017 and has since gained a large following among developers.

One of the main features of Nest JS is its modular architecture, which allows developers to easily break down their application into smaller, reusable components. This makes it easier to develop, test, and maintain large-scale applications.

Nest JS also integrates with a variety of popular libraries and technologies, including Express, Fastify, GraphQL, and Socket.io, making it a flexible choice for a wide range of use cases.


What is Next JS?

Next JS is a framework for building server-side rendered (SSR) or statically generated React applications. It was created by Zeit and released in 2016, and has since become a popular choice for building server-side applications with React.

One of the main features of Next JS is its ability to automatically optimize the performance of React applications. It does this through features like code splitting and automatic static optimization, which helps to ensure that the application is fast and efficient.

Next JS also provides a range of developer-friendly features, including automatic code splitting, hot module reloading, and automatic optimization of images.


Nest JS vs. Next JS: Key Differences

While both Nest JS and Next JS are popular choices for building server-side applications, there are some key differences between the two frameworks that you should be aware of.

  1. Language and TypeScript Support: Nest JS is built with TypeScript, while Next JS is built with JavaScript. This means that if you want to use TypeScript in your application, Nest JS might be a better choice. However, if you prefer JavaScript or are more comfortable with it, Next JS might be the better option.

  2. Architecture: Nest JS uses a modular architecture, which allows developers to break down their application into smaller, reusable components. Next JS, on the other hand, uses a monolithic architecture, which means that all the code for the application is contained in a single codebase.

  3. Rendering: Nest JS is primarily designed for building server-side applications, while Next JS is designed for building server-side rendered or statically generated React applications. This means that if you want to build a server-side application with React, Next JS might be the better choice.

  4. Performance: Next JS is designed to automatically optimize the performance of React applications, through features like code splitting and automatic static optimization. Nest JS does not have these performance-enhancing features built-in, so developers must manually optimize their application for performance.


Nest JS and Next JS Use Cases

Now that we have a good understanding of the key differences between Nest JS and Next JS, let's look at some common use cases for each framework.


Use Cases Nest JS:

  1. APIs: Nest JS is a great choice for building APIs due to its modular architecture and integration with popular libraries like Express and Fastify. Its use of TypeScript also makes it a strong choice for larger, enterprise-level projects.

  2. Microservices: The modular architecture of Nest JS makes it a good choice for building microservices, as it allows developers to break down their application into smaller, reusable components.

  3. Real-time Applications: Nest JS integrates with Socket.io, making it a good choice for building real-time applications like chat apps or collaborative tools.


Use Cases Next JS:

  1. Server-side Rendered React Applications: Next JS is primarily designed for building server-side rendered or statically generated React applications. If you want to build a server-side application with React, Next JS is a strong choice.

  2. Static Sites: Next JS can be used to build statically generated sites, which can be easily deployed to a content delivery network (CDN). This makes it a good choice for building fast, scalable sites that don't require a lot of server-side processing.

  3. Progressive Web Apps (PWAs): Next JS has built-in support for building progressive web apps, which are web applications that can be installed on a user's device and behave like native apps.


Conclusion:

In conclusion, Nest JS and Next JS are both powerful frameworks for building server-side applications. Which one is the best choice for your project will depend on your specific needs and requirements.

If you want to build a server-side application with TypeScript, Nest JS might be the better choice. Its modular architecture is also well-suited for building APIs, microservices, and real-time applications.

On the other hand, if you want to build a server-side rendered or statically generated React application, Next JS is a strong choice. Its performance-enhancing features and support for building static sites and progressive web apps make it a versatile choice.

Ultimately, the decision will depend on your specific needs and requirements. Both Nest JS and Next JS are strong choices for building server-side applications, and either one could be the right choice for your project.
