Node.js vs Go – What to Choose for your project ?

The process of web app development can be compared to an iceberg. There is part of the app that a user sees, meanwhile, the rest remains unseen. This is what we call “back end”, imperceptible and mystical.

In the majority of web applications, there is significantly more non-UI code than the code that is directly related to the interaction with the end user. Information needs to be stored and retrieved, logic has to be followed, results – calculated. Complex systems contain all kinds of data and logic in the background. Back end development is about writing code that is not seen directly.

Among technologies used for back end programming, there are Go and Node.js. They are both relatively new and are gaining more and more popularity but in very different ways, and for very different reasons. They are part of a movement away from traditional server-side languages (PHP, Java) used for backend development.

So let’s find out what technology suits your project best. How do you recognize the winner in one of the two next-generation web app development languages: Go (Golang) vs Node.js? We will try to help you figure out the answer and choose whom to hire – Go or Node.js developers offshore.

What is NodeJS?

NodeJS is a platform for utilizing JavaScript as the backend of your web application. As it were, it enables you to utilize the Web’s most well-known language for a whole web application.

This has prompted NodeJS turning into the quickest developing stage on the web, by far.

NodeJS is an inexorably well-known platform based on a quick, JavaScript-based runtime V8.

V8 is a JS virtual machine made by Google that is intended to assemble adaptably, arranged applications. It accumulates JavaScript code to local machine code, utilizing some perplexing improvements. V8 additionally does the memory allotment and junk accumulation of JS objects.


What is Golang?

Golang is a coding program that was made by Google. It likewise fills in as a community project that is open source. It is simple for amateurs and can be perused by different developers. Golang doesn’t have a vast arrangement of highlights like different projects like C++ or C.

One preferred standpoint that Golang has is its memory effectiveness. For example, Golang documents take up just 2 KB of memory rather than Java’s records that are around 1 MB.

This implies Java will take up a considerable measure of your PC’s RAM memory and could possibly close it down because of low memory. Let’s discuss



JavaScript vs Golang development performance

Famous for non-blocking I/O processing approach, Node.js masters in creating real-time, powerful applications, including desktop and web ones. However, Golang surpasses JavaScript in:

• raw and real-life performance;

• maturity;

• scalability;

• concurrency.

JavaScript is commonly preferred by frontend programmers and used by many software development companies, while Golang development tools are great and indispensable for backend, web, and server-side services. Garbage collection of Go is based on the progressive mark-and-sweep algorithm, which adds to the advantages of this technology. Golang codes are clear, efficient and even shorter than the ones written in JS.

However, Go is quite young, with an actively growing ecosystem. Testing, error handling, and debugging can be still challenging for Golang developers. Additionally, new coding concepts called “goroutines” are not easy to learn. They include channels, threads, pointers, coroutines, which are innovative, but difficult to master.

Therefore, many business owners prefer to order software development services from reliable companies with an expertise in Golang. Overall, the language is well-suited for web, server-side and network apps, as well as for command-line: standalone or simple ones. Go codes are syntactically clean, and scalable. As to system-level programming, Golang technology demands solid skills and rich engineering experience. You can prefer Node.js for the complex tasks and wait until Go language evolves subsequently, or simply to contact our professional Golang developers to get high-quality services right now!


Nodejs vs Golang Comparison of Key Features

Go, although using compilation, features easiness of programming similar to that of an interpreted language. So, at first sight, Go may appear a perfect solution for application programming. The fact that it is getting increasingly popular among developers speaks for it, too, however, Node.js does not seem to be losing ground because it also has certain advantages. We will compare the characteristics of Go vs those of Node.js to see in which situations each of them can be a better choice.



Performance Medium Excellent
Scalability Medium Easy
Concurrency Poor Excellent
Error handling Medium Difficult
Developers’ tools Excellent Poor
Learning curve Easy Difficult
Availability of developers Excellent Poor

Let’s look closer at each of these criteria.


Node.js is based on JavaScript, an interpreted language, which renders it generally slower than most of the compiled languages. And indeed, in this respect Go beats it by far, as one of the goals its developers tried to achieve was better performance.

However, if truth be told, such comparison of Node.js vs Golang is fair in terms of raw performance – the CPU performance with no other load. Here Golang is definitely the winner, although, in real life performance both Node.js and Go can show similar satisfactory results, as the overall performance of the server may be affected by other factors.


Scalability and Concurrency

Node.js is single-threaded, which means that the execution instructions are performed in sequence. And this may be its Achilles’ heel when it comes to large applications requiring massive scaling with a lot of parallel processes executed at the same time. JavaScript allows some concurrency with event callbacks, however, they are not too effective.

Go, in its turn, is much better suited for scalability due to its coroutines which it calls “goroutines”. Goroutines allow multiple threads to be performed simultaneously with parallel tasks executed easily and reliably. So, in this round of Go vs. Node.js, Go is definitely the winner.


For this easy and convenient scalability, Go became the language of choice for Docker and Dropbox who recognized the options Go offered for building large applications with considerable scaling capacity.


Comparison based on the Level of Maturity

We will first compare Golang and Node.js based on their maturity level. When we talk about Go, it is adequately mature and robust although introduced in 2009. On the other hand, Node.js is also showing the same maturity and enjoys the support of the larger audience.

But the problem lies with the changing API for which the developers may face issues while writing the Node modules.


Assessing on the Performance Basis

Node.js basically a JavaScript runtime integrated language and is usually on the slower side when it comes to comparison with Go, the improved compiled language. In fact, Golang performs much better than Node.js, which cannot offer the same optimum service as CPU bound memory due to the JavaScript.

So, Go outperforms Node.js on this front but having said that the reality is that both offer more or less the same kinds of server results in the end.


The Concurrency

The major difference between the Node.js and the Go is that while the former utilizes the event called mechanism, the latter is making use of the co-routines known as Goroutines. The mechanism is based on the single-thread and this where the Node.js lacks behind the Go language.

But it is offering the async generator support known as the semi-co-routines. On the contrary, the Go language makes use of a lightweight thread that is managed by the Go runtime. The interactions between the Goroutinesbecome much easier due to the channels.


Who is More Scalable

Like Concurrency, the Go language is able to win over Node.js in scalability. As such the Node.js is not regarded as suitable for the large projects due to weaker parallel process.

However, again the Goroutines prove to be a major asset for the Golang as it provides multiple threads to be performed in one go along with the parallel tasks.


Node.js vs Go Comparison Table

The primary Comparison between Node.js vs Go are discussed below:

The basis of comparison Between Node.js vs Go Node.Js Go
Performance As Node.js is based on JavsScript which is interpreted language is generally slower than compiled languages. But in real life Go and Node.js provides satisfactory results as overall performance will be affected by so many factors. Go gives a good raw performance for CPU and memory-bounded tasks as it is based on C language which is good at performance. So Go is the real winner in terms of performance.
Concurrency Node.js is a single threaded and uses event-callback mechanism. So we can’t achieve concurrency using it. Go language uses goroutines and lightweight thread communication mechanism to achieve concurrency as it is elegant and seamless due to channels.
Scalability Node.js is weaker in terms of achieving the parallel process for large projects as it uses event callback mechanism though it will get done a job for smaller projects Whereas Go has “goroutines” which is a big advantage as they handle parallel threads very effectively. In general parallel tasks will be complex but with Go, we can do simply.
Tools for Developers Node.js has so many tools available for developers to develop every possible application as we have platforms, examples, and libraries. As Go is a new language, it has good libraries and packages to use but comparatively, with node.js it has less tool as a developer will do more programming work.
Error Handling Node.js uses “catch/throw” mechanism for error handling as errors will catch immediately after the occurrence and familiar among developers. But in last final application will be sub-optimal Go language uses explicit error handling as error codes return after program flow completes – which is a difficult process but gives reliable application with consistency.
Learning Curve Node.js has a lot of resources available both online and offline as it is the most popular programming language with huge developer communities by which we can assistance while learning Whereas Go has very few resources for learning as it is a new language we need to follow specific rules, concepts to learn and clear doubts. As Go is backend language we need to use JavaScript for the frontend.
Developers availability Node.js has a lot of developers as it is a popular language for web development. We can easily form a team with a different level of Node.js knowledge people. Whereas Go, we have very fewer developers as it is a new programming language. Still many are learning as resources also minimal. Forming a team with Go developers is a difficult task.


The need for Golang Development

As well as Node.js, Go language is perfect for the development of networked apps. Meanwhile, it is really good for database driven applications, as Cloud Datastore is a great solution for businesses that set a high value on their precious data. Golang was created on the base of C and C++ conservative languages; it’s a general-purpose, compiled language, but it stands out from its precursors for:

• fast compilation;

• easy dependency and memory management;

• rich type systems;

• powerful multi-core support.

Experienced programmers switch to Golang development not only from C and C++ but from Python, Java, and Node.js. Go is simple, scalable and clean. Therefore, many developers have an urge to replace other languages for software development with Golang to improve its performance, compilation capabilities, and concurrency.


Which is best?

This depends on a variety of factors such as:

  • Type of project
  • Budget
  • The current skill level of your developers
  • The size you intend to scale to in the future

Any skilled development team will know what languages and tools to use for a given project. The important thing is to define your requirements well. There are no silver bullets in software development. Every choice you make is a trade-off that will bring its own set of pros and cons.
