As per Stack Overflow Developer Survey 2022, Spring was among the most-loved frameworks, while Nestjs is gaining popularity, enabling developers to build highly scalable server-side applications leveraging a Node.js environment.

Though they both are popular, widely used and have large community support, the choice between them depends on your needs. This article discusses the key features of each framework to help you understand which one is ideally suited for specific tasks.

Spring vs Nestjs: Head to Head

What is Spring?
Spring framework is an open-source Java framework that offers an all-inclusive infrastructure for building Java applications. The framework is lightweight, loose-coupled, and includes dependency injection, aspect-oriented programming, and inversion of control in its core. Overall, it presents a mature ecosystem for developing complex and enterprise-grade applications. Again, it is the world’s most popular Java framework.

Note: When looking for Spring, we often see “Spring Boot,” another framework built on top of the Spring, extending the Spring’s capabilities.

What is NestJs?
It is a progressive node js framework, allowing developers to leverage and extend the Nodejs functionality.

When we refer Nodejs framework, it means the Nestjs app requires Nodejs runtime to execute. In particular, NodeJS is JavaScript runtime environment that utilizes Google’s V8 JavaScrpit engine, renowned for its exceptional speed in executing code, which allows developers to run JavaScript outside the browser.

Consequently, Node.js has achieved widespread popularity by allowing developers to build native-like, server-side, and highly scalable applications using JavaScript.

NestJS not only harness the capabilities associated with Node.js but also amplifies the powers of this popular framework. It also allows developers to leverage renowned Node.js frameworks like Express and Fastify.

Additionally, NestJS provides the added advantage of TypeScript, allowing developers to code in JavaScript while enjoying the benefits of strong typing and enhanced tooling.

In addition to the discussed benefits, NestJS encompasses a range of remarkable features. Developers can take advantage of OOP (object-oriented programming), FP (functional programming), and FRP(functional reactive programming), which provide them with a multitude of programming paradigms to choose from. This versatility enables rapid development and enhances the flexibility of the framework.

Let’s delve into the distinct features of the frameworks that contribute to their widespread adoption, emphasizing the factors that distinguish them from each other.

Key Features of Spring
The Spring offers a range of features to simplify large and complex app development. Some of the key features of the framework include as following:

Dependency injection: Dependency injection is the core of the spring framework. DI allows developers to build loosely coupled applications.

Support for Aspect-oriented programming: AOP or aspect-oriented programming promotes modularity of cross-cutting concerns (examples of cross-cutting concerns are logging, error handling, caching, transitional management, and authentication). In other words, it promotes reusability by encapsulating the cross-cutting concerns into aspects. Later the aspects can be applied to various parts of the system, promoting code readability and maintainability.

Data access framework: When it comes to communicating with a database, many frameworks do not provide the amount of ease required to focus on development parts. In the case of Spring, it greatly simplifies database communication by incorporating support for Java access frameworks such as Hibernate, JDBC, and JPA(Java persistence API).

Transaction management framework: Spring comes up with its own transaction management component for managing transactions in an application, streamlining the transaction management process.

Application testing: Testing is a critical process that enables the initial evaluation of an application to ensure it functions as planned. It contains various testing features that simplify the testing of the application. These features help in efficient and effective testing.

In addition to the features mentioned above, the Spring Framework offers notable features like a well-defined MVC structure, web service support, a core container, etc.

Key Features of Nestjs
NestJS, a popular framework for building Node.js applications, includes a diverse set of features that contribute to rapid application development. Below are some key features provided by NestJS:

Progressive framework: As mentioned above, it is a progressive framework, though “progressive” has a broad meaning, and it can have different meanings. In the context of software development frameworks, it refers to a progressive approach where you start with small and progressively build something bigger. For example, NestJS can be a perfect choice for building a single-page application, and later the new functionality can be added to the application over time, enabling the creation of complex applications in a step-by-step and straightforward manner.

Scalable: The framework allows the development of scalable applications so that if the app’s popularity grows over time and requires more resources to handle the increased demand, it can be scaled without compromising performance.

Extensible: Extensibility refers to extending the framework’s capabilities beyond its core functionality. Its modular structure allows developers to add more functionalities, features, and modules without requiring significant modification to the existing database. As a result, you can efficiently customize your framework with ease.

Versatile: Though scalability and extensibility are part of a versatile ecosystem, the Nestjs framework has the ability to integrate with Express and Fastify easily, enabling the framework to achieve different functionality in order to serve a wide range of requirements.

Spring vs NestJs: The Pros & Cons
Every framework, including Spring and Nest.js, has its flaws and limitations. This is because frameworks are developed to address specific problems, aiming to simplify development processes. As a result, it’s unavoidable to encounter limitations associated with each framework. In this section, we will explore those of Spring and Nest.js.
