Published: 2023-11-02 12:22:54

NestJs and Spring are both open-source, full-stack frameworks for building modern web applications; the first one is TypeScript-based, while the Java Spring framework leverages Java’s capabilities. 

They both support dependency injection and include application testing features, encompassing MVC structure, which often leads to confusion and debates on Spring vs Nestjs on the internet.

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.

**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.

**Spring Pros & Cons**

**Pros – Spring**
Spring is a renowned framework that excels in developing complex and large applications. It encompasses crucial features like Aspect-Oriented Programming (AOP), Plain Old Java Object (POJO) paradigm, and a wealth of functionalities that ease the development of secure, robust, and modern Java-based applications. By opting for Spring instead of Nest, you can leverage the following advantages:

- Various kinds of pre-defined templates for Hibernate, JDBC, and JPA technologies, eliminating the need to write complex code. 
- Dependency injections for loose coupling, increasing modularity and flexibility in application design. 
- Spring streamlines testing by including features like dependency injection, mock objects, and integration testing support. 
- Spring enables rapid application development with its rich set of pre-built components, simplified configurations, and efficient development patterns.
- Spring offers strong abstraction capabilities, allowing developers to focus on business logic while abstracting away complexities of underlying technologies and frameworks.
- Spring’s lightweight Inversion of Control (IoC) container enables the creation and deployment of applications on systems with restricted memory and CPU resources.

**Cons – Spring**

- It is complex to learn and use, especially for beginners, as it comes up with a lot of pre-built features that require prior knowledge of the acronyms and abbreviations it uses.
- The allowance for dependency can make your development easier; at the same time, it can increase the risk of security vulnerabilities. 
- Many people praise frameworks as having unopinionated in nature; Spring is not opinionated that has its disadvantages.
- Due to its complex configuration, it can be difficult to debug sometimes.
