You might not expect it when you see something this small, but Express.js (simply referred to as Express) is a critical component of many web development projects. That surely has to do with the fact that it’s an essential component of MEAN, one of the most widely used tech stacks in web application development.
A small web application server framework, Express is impossible to understand without talking about Node.js first. That’s because Express leverages Node.js web server functionality to simplify its APIs and provide new functionality. In fact, Node.js is boosted by the presence of Express, which, in turn, powers the backend part of the MEAN stack.
A favorite in the development world, Express consistently ranks among the best web frameworks in the market. That’s why any web development team worth its salt almost always has an engineer capable of using Express to empower web development projects through the MEAN stack.

Express, on the other hand, is a small framework based on Node.js and designed to build web applications and APIs. It’s a minimal tool with many plug-ins that extend its functionality. Express makes it easier to organize the app’s architecture on the server side, adds utilities to Node.js’s HTTP objects, and facilitates their rendering.
Since Express is so closely related to Node.js, its use cases are, too. In other words, both technologies work together to empower the backend of different web development projects. Some of the most common include the following:
While Express and Node.js are great for these types of processes, it’s important to note that they aren’t a good match for projects that require heavy server-side processing, which overrides the benefits of Node’s event-driven, non-blocking I/O model for incoming requests.
It’s impossible to think of Express without the MEAN stack, one of the most popular tech stacks in development. Given MEAN’s popularity, it’s not surprising that Express enjoys a widespread reputation as a great minimal tool to power the back end of numerous web development projects. In fact, according to Stack Overflow’s Developer Survey, Express has consistently ranked among the top 5 web development frameworks alongside jQuery, React, Angular, and ASP.NET.
Additionally, Express is a powerful tool that’s powering the web operations of some highly renowned companies, including IBM, Uber, Accenture, and Fox Sports. This comes to show that Express can deliver a notable performance that has been tried in production environments with high demand and a superb quality level.
While Express isn’t the only back-end web framework out there, it doesn’t seem like its popularity will decrease anytime soon. That’s because it isn’t just part of the MEAN stack but also contributes to other popular stacks, such as MERN and MEVN.
The fact that it’s part of a very popular tech stack shouldn’t be the only reason why a team picks Express to work on its web development projects. There are multiple advantages to using Express, including the following:
While there are plenty of benefits when using Express, it’s also important to point out that there are a couple of disadvantages that can derail a web development project. The 2 most important ones are:
You can certainly work on web development projects without ever using Express and still get great results. But why would you do that when you have a framework that’s capable of getting the most out of Node? By choosing Express for the backend of your web development, you’ll be taking a step toward increased efficiency and high scalability.
Sure, it won’t be able to power all your web development projects, but being a part of the MEAN stack means Express can be used to build a respectable range of web applications that allow real-time collaboration and communication. What’s best, you’ll be able to do so through a very simple and easy-to-use framework that’s become an essential part of modern web development.
