ExpressJS vs NodeJS – Pros and Cons

Let us now explore the advantages and disadvantages of using ExpressJS vs NodeJS for web development.

Pros & Cons of ExpressJS


  • Has some robust routing APIs.
  • The platform is easy to use and offers a set of some powerful features.
  • It can facilitate easy integration with databases like Redis, MongoDB, etc.
  • Contains a customizable and extendable architecture.


  • Doesn’t have an ORM system integrated or any other option to easily interact with databases.
  • Employs extensive middleware functions that can often lead to a codebase full of bases.

Pros & Cons of NodeJS

The advantages imparted by NodeJS are numerous and the platform is beneficial for the development of all different kinds of applications. Irrespective of whether you build a streaming app or a payment system, the development platform is advantageous.


  • The platform is highly scalable despite being single-threaded.
  • Imparts unmatched speed because of its non-blocking architecture and the feature of the event loop.
  • It contains a vast library of Javascript modules that helps simplify web app development to a great extent.
  • Debugging is easy since it employs the Javascript engine of Google Chrome’s V8 for code execution.


  • Lacks support from a few databases like relational ones. The developers however solve this challenge with the help of ExpressJS.
  • Leverages an asynchronous programming model and is therefore confusing for entry-level developers.
  • Though, when a developer masters this application it helps enhance the performance of an app and its responsiveness as well.

ExpressJS vs NodeJS

  • Performance

ExpressJS is a flexible and minimal NodeJS framework that offers a powerful set of features for developing web applications like sessions, routing, caching, etc. Comparing NodeJS with ExpressJS, the latter helps manage all the clutter with server setup.

On the other hand, NodeJS leverages a non-blocking, event-driven I/O model, making this option an efficient and lightweight option for the server environment. This environment has to handle numerous concurrent connections with low latency. Developing such an application is easy with NodeJS since it imparts speed and high performance. Build websites with NodeJS to obtain the benefits offered by the platform.

  • Scalability

Primarily, Express is a middleware and routing framework that helps develop APIs, web apps, and mobile apps. NPM can help install Express as a dependency since it then becomes easy to use with NodeJS. Additionally, it also extends the capabilities of base Node to develop a service or an application. Node and Express make a deadly combination when working together.

The asynchronous operations of NodeJS enable it to provide high throughput and scalability to the application. Multiple threads are not made by NodeJS instead, all connections are easily managed within a single thread. They are pushed into the event loop queue. All the events are then handled one after another by the thread from that queue.

  • Testing

The major advantage of using ExpressJS is the platform’s ease of testing. It offers all the required tools that help make the testing process easy. Having said that, you can test the functionality of your application in the best possible way. Any testing suite can be used, such as Chai, Mocha, Jasmine, etc.

When using NodeJS, the platform makes some bigger assumptions regarding the structure of your application. That said, you will not have to worry about setting the directory structure for your app. This helps make writing tests of your app easy, but it also means that you may find several potential issues with your code structure.

When to Choose NodeJS?

Hire a NodeJS development company when you have to get a highly scalable and productive web app built. The best part about using this framework is that you can use the same set of code for both the server-side and client-side of your application. Furthermore, NodeJS has an interactive interface, enabling easy integration with other third-party libraries and tools such as Angular, MongoDB, React, etc.

If you are a company looking for a cost-effective development solution, NodeJS is ideal for optimizing expenses. This is only possible because of the open-source nature of the platform.

Hence, it is the perfect choice to build a lightweight application or MVP for startups looking to fit into the market. Furthermore, ExpressJS is a great choice for web app development.

You can develop the app the way you like, and there is nothing wrong or right with it.


When it comes to using ExpressJS vs NodeJS, you can easily use one option along with the other to achieve a fully-functional web or app. NodeJS is used for almost all applications and is a broader option. On the contrary, ExpressJS is a suitable option for CEOs, product owners, and CTOs looking to build an MVP or a test product to fit market requirements.
