When a company provides a service to thousands or millions of users, they want to ensure that all relevant systems run like a well-oiled machine both for their operations and for the users. In backend development, this desire prompts hundreds of companies every day to choose the languages, software, and frameworks that will drive their service, but the choice is anything but easy. The use of Node.js for backend is one very popular choice, but it is hardly the only one.
Dozens of tools are available to businesses working on their server-side architecture nowadays, with each offering unique strengths and downsides. Given that Node.js powers over 100 thousand websites and some of the biggest online services around today, we decided to examine how well it works for backend developers all over the world.
Without further ado, let’s take a look at what makes Node.js tick and how well it compares to other tools and technologies in backend development services.

About Node.js in Two Words
What are the advantages of using it?
Many developers choose NJS for its speed, which originates from the V8 engine’s unique ability to compile JS code into machine code and have it run near-instantly. Furthermore, one of its biggest advantages is scalability – the ability to add nodes to existing systems quickly. In fact, it’s practically spelled out in the framework’s name.
Finally, it has a thriving community behind it, stable updates are released regularly, and there is a whole foundation (OpenJS Foundation) responsible for overseeing its growth.
Examples of use
NJS is a cross-platform framework, allowing programmers to build for multiple platforms (desktop, web, mobile). To get a better idea, take a peek at an extensive list of software types that can be developed with Node.js. As for examples of these solutions, it is difficult to imagine services, platforms, and software with a higher level of prominence:
Is Node.js Good for Backend?
- Streaming services
- Chat systems
- Online games
- Single-page applications
- REST APIs
The input/output model used by NJS makes it very handy for streaming. In particular, active connections allow users to upload and download data simultaneously rather than the process taking place in turns.
This is another type of solution that plays to the strengths of the framework. When NJS is deployed with the right web sockets, even the most popular and active chats will function as expected, handling the massive traffic and maintaining great message delivery speed.
Online games usually involve a large number of connections that few runtime environments are equipped to handle. Thankfully, this one is built to handle such situations, enabling fast synchronization of data between the client and server and even allowing players to engage in multiplayer modes.
Single-page applications (SPAs) are a great option for NJS work because pages can be rendered on the server before this happens in the browser, so the user ultimately gets to see the content faster. This advantage is often compared to the abilities displayed by React and Angular.
As you might have noticed, all of the aforementioned solutions involve a large number of users and quick responses, which are exactly the kind of conditions that NJS is tailored to.
When You Shouldn’t Use Node.js for Backend
Despite the impressive nature of this runtime environment, it can’t do everything, and definitely cannot do everything well. Thus, let’s examine some scenarios and circumstances where the use of it is not the best choice.
- Frontend development
- CRUD apps
- CPU-heavy applications
CRUD applications are known for performing 4 basic types of SQL operations – create, read, update, and delete. With all the data coming from the server in a quick and efficient way, there is no need to build additional APIs and infrastructure with NJS. CRUD apps will work just fine without it.
Though the runtime environment is equipped to handle countless simultaneous connections, we see an entirely different picture when it comes to big requests. The event loop present in it does not distribute CPU effectively for big requests, causing severe blockages and speed drops. Short and small queries are much more suitable and encouraged.
Node.js Compared to Other Backend Development Tools
Now that we have gone over the basics of the framework, let’s examine how it stacks up to the other leading tools used by programmers.
Node vs Java for backend
Both options are great in their own right, especially under different circumstances. For example, Node is the more popular and helpful choice when it comes to desktop apps, while Java dominates the Android platform. Another example of their differences pertains to threading: Java web servers are multi-threaded (code is processed more efficiently), while Node is single-threaded, causing blocks and slowdowns when bulky requests are sent to it. On the other hand, Node is much easier to learn and has a faster development time than Java, as well as better scalability with hardware.
Node.js vs Python for backend
Python is the better choice when it comes to servers performing numerical computations and machine learning, while Node.js excels in most general types of web services, especially real-time applications. Unlike Python, NJS supports asynchronous programming by default, allowing for better and faster scalability.
Node.js vs PHP for backend
PHP has a much broader level of support for server management systems, and is recommended for services that will use CMS and/or relational databases. It also requires less code, though Node.js makes it much easier to reuse code. NJS also boasts a faster execution speed and does a much better job of delivering data from the server efficiently in service calls.
What about GO?
Node.js is preferred by developers for its error-handling mechanics and wide array of tools available, while GO generally executes code faster and better copes with CPU-heavy tasks. Another area where GO excels is scalability, where it is the superior of the two.
C# backend development primarily takes place with ASP.NET, which tends to offer a better quality of code and faster speed (due to multithreading). Conversely, Node.js has a much easier syntax allowing for faster code writing, supports diverse code sharing, and has a much bigger Package Manager than its ASP.NET counterpart Nuget.
The two options have similar levels of performance, so their main differences lie in syntax and ecosystems. Node.js is much faster to write allowing for faster prototyping and testing, while Scala’s syntax, though complex, is much more strongly typed and safer to use. In terms of ecosystems, both are expansive, but NJS takes the cake with its larger community and wider array of tools.
Without a doubt, there is more to compare about these languages and frameworks, and whole articles could be devoted to each comparison. For the sake of brevity, we opted to give you the key points in a nutshell.
