NestJS vs. Express.js: Which One is the Best Framework for Server-Side Application Development? [Updated]

nestjs vs express js which one is the best framework for server side application development itechnolabs

Node.js was created as a method of taking the V8 engine which was part of the Chrome web browser, to become one of the most important technologies available that are available. It has helped JavaScript to go beyond its initial purpose as a front-end scripting language into a fully functional multi-purpose programming language.

iTechnolabs along with other software development companies appreciate the idea that they can use the same code to develop frontend and backend development. It’s not just more enjoyable and more comfortable, it also facilitates communication among team members. If my backend was using Laravel as well as Django for a platform then I’d have to know PHP or Python to know the logic behind the code.

Don’t interpret this as a reaffirmation of using one programming language that can dominate all others. We’re all in agreement that JavaScript is, of the various options available that are available is not the best choice for the job. It’s good to have an easy and understandable language to build your backend.

Node.js for use as a frontend system is virtually identical to Express.js and Express.js to the point that it is considered to be to be the most reliable standard server platform for Node.js. However, it’s far from the only option available and NestJS is a formidable contender which aims to fulfill the same role within the JavaScript ecosystem.

What Is a Framework?  

Before getting into the in-depth nitty of the differences, it’s essential to understand what’s being discussed. The two NestJS vs Express js, are frameworks specifically designed to create backend web apps.

A framework is a collection of tools used as a base or basis for creating something. In terms of formal definition, the term “software framework” refers to a Software framework that can be described as an abstraction that provides general functionality. It can be modified by a user’s code, thus creating software for specific applications.

It is a generic tool that is customizable by the user. It is designed to accelerate development by providing tools that could otherwise take a considerable amount of time to set up and up and running. Imagine it this way starting from scratch the same as drawing a drawing on a blank canvas having a frame similar to creating artwork from sketches.

A Brief Comparison Between NestJS vs. Express.js –


What do you think of being a top dog in the marketplace? Express.js is huge in the sense of its community. The search for tutorials, support, and helpful techniques is easy, but the most appealing feature is undoubtedly the huge number of plugins that are ready to enhance Express.js.

The reason is that Express is a light, non-opinionated framework. This means that, right off the bat, the framework is about as simple as it gets and offers only a few features in terms of features. The process of starting from scratch is likely more difficult as a large portion of the fundamental components has to be constructed from the ground starting from scratch.

In return, the developer enjoys more freedom. To return to our sketch metaphor, you can be more creative when you do not have to draw inside the boundaries.

If you’d rather the speed of a plugin over flexibility, they can be used to help speed up the process and, in a sense to give you the freedom of a minimalist framework, but with the possibility of adding more robust solutions, you should consider Express.js is the ideal framework that is right for you.

However, it’s not all rainbows and sunshine. Different plugins may not be compatible with each other, and there’s the additional step of figuring out if a particular set of plugins can work with each other or if you’re required to investigate.


It’s a lot like NestJS and can be described as the exact opposite of Express. It’s a highly opinionated framework that follows the model that is “convention over configuration.” That is we give up flexibility in exchange for rapidity and standardization. NestJS is built on Angular which is why, as one would expect, it’s designed to be used in conjunction with TypeScript. (You could write in Javascript however if you’d prefer.) 

TypeScript is an extension of Javascript developed by Microsoft It is designed for use as a completely written alternative to Javascript which aims to address many of the complaints regarding the language. If used properly it can help create bug-free code without losing the simplicity and readability that comes with standard Javascript.

NestJs enforces the MVC structure upon the programmer, separating the components of an application into three key elements that are the model, the view as well as the controller. It’s among the most well-known architectures available, and NestJs provides a variety of features for each of the components.

NestJS vs Express js: Pros and Cons

Both frameworks are excellent choices for small-scale projects. It is not a good thing for either of them to choose the winner. But there are some points to be aware of.

NestJS is the only foolproof solution. If you’re a web developer who is looking to get your feet wet in web backends for the very first time or if your team just beginning by establishing the safety net of a well-known framework is a great asset. With NestJS you will be able to learn about extremely well-known web-based development architectures as well as learn the fundamentals of the hugely well-known Angular. It’s like making two birds a stone.

In the end, NestJS is also fantastic for professional users. If the project you’re planning to work on falls within the NestJS model, you’ll be cutting down on a lot working on your project.

On the other hand, there’s a reason behind that explains why Express.js is so well-known. Its flexibility is unbeatable and is perfect for teams who want to try new or non-standard solutions. Frameworks that are lightweight such as Express.js encourage creativity and are a great solution for projects that require an outside-of-the-box approach.

Both are competent, and in terms of the ability to scale While NestJS is a little more flexible to expand, Express can offer a similar, if not better, performance by putting in a little effort. 

NestJS is similar to one of the Lego models of a Death Star: if you are looking to create a Death Star, then it’s the ideal solution for you. However, when you’re trying to construct a customized vehicle, you’re better off with a standard Lego set. This is the purpose Express.js is designed for.
