Node.js vs Golang 2019: Choose the Right One for your App Back-end

Reading Time: 5 minutes

Node.js and Golang both are emerging technologies for mobile app’s back-end development. This blog is going to compare both technologies and lets you know which one enjoys having an edge over others.

No one would be ready to compromise with the quality of their business app that they are going to develop, be it for startup or enterprise. So, the question is, what does define quality of applications?

Well, there are a number of factors such as code quality, scalability, performance, features, etc., contribute an active participation to enhance an app’s quality. Back-end is another most important factor that has also an active role in defining app’s quality.

Even if your mobile app is complemented by the above factors, but not having a quality back-end, it will not be able to fulfill your business requirements.

So, now it’s already prima facie – the importance of a quality, powerful and secure back-end for your application. You need to hire a right app development service that leverages the right tech stacks to develop a secure back-end for your mobile application.

There are myriads of back-end development technologies like AWS, Node.js, PhP, Python, etc., available for developers. So, choosing the right one for your business app matching your requirements and target audience’s expectations sometimes becomes quite stringent.

Meanwhile, you could in fact avoid the situation by focusing on the most popular tech stacks for back-end development, which are none other than Node.js and Golang. Now, you may be keen in knowing which one will be right for your app, isn’t it?

Is Node.js better than Golang? 

Well, we are going to discuss here Node.js vs Golang 2019 and will help you in choosing the right one, fitting your business requirements, goals and expectations. Before getting delve into Node.js vs Golang 2019, let’s introduce both.

Node.JS Vs Golang - AppsChopper


Initially released on May 27, 2009, Node.js is one of the most popular open-source cross-platform technologies for back-end development. It comes with the ability to execute JavaScript code outside of browsers. Developers using Node.js, get a flexibility to use JavaScript for coding command line tools and also for server side scripting. Governed by Node.js foundation, Node.js  is able to simplify the app back-end development and makes it more dynamic, with a single programming.


Is Golang the same as Go? Well, first appeared on November 10, 2009, Golang, also known as Go, is another most popular open-source programming language.

Golang is basically a compiled and more statically typed programming language. Developed by Google, Golang facilitates developers to create a more stable, simple, efficient and reliable back-end for apps.

Node.js vs Golang: A Neck to Neck Comparison

Maturity Level


It is highly mature but not as Golang – the actual reason is, this technology actually works with numerous APIs, which generally go for continuous changes. Node.js also supports the large audience.


Golang shares a higher maturity level compared to Node.js and supports the large audience.

Both Node.js and Go were introduced in the same year and entered in the market.



Why is Golang faster than Node.js? When it comes to performance, Node.js is slower than it’s rival Golang. The reason is that Node.js is basically a JavaScript integrated language and unable to offer the same kind of performance similar to CPU bound memory. Besides, it also leverages V8 engine and sometimes the process to execute program takes time and thus impacts the overall performance of Node.js

Golang is, on the other hand, is a fully compiled language and performs outstandingly. The main reasons are that it has lower app loading time and a higher response time. It doesn’t use any virtual engine and ensures the process of program execution is often fast



Node.js is not considered to be much suitable for those of larger projects, mainly because of weaker parallel process. So, it is considered to be less scalable.


Golang is said to be highly scalable and the best for developing larger projects. Goroutines are considered to be the most important thing of Golang, which offers numerous threads that can be performed in one go with parallel tasks.



Node.js is basically single threaded and this is the reason why certain CPU bound tasks block the event loop as well. This impacts on your app’s background performance and makes your app slow and thus annoying for your target users.


Golang has a better and powerful concurrency and is considered to be right for larger back-end development related projects. Golang environment enables developers to run numbers of goroutines quickly, even without much use of RAM.

Error Handling


When it comes to error handling, Node.js works on the traditional method to catch the issues quickly when they take place and perform greater solutions.


Golang, on the other hand, works to separate compilation and run-time error, which makes it really tough to handle errors. This certainly increases difficulty for majority of developers.

Learning Curve


Based on JavaScript, Node.js is one of the most popular tech stacks for app back-end development. This makes the technology easier to learn for individuals and they can then easily start developing the back-end.


Is Golang a back-end language? Golang is itself a language. So, developers need to have an in-depth knowledge of various important rules, process, programming concepts, etc., to develop back-end for web and mobile app.

Developer Tools


Node.js is available with various ready-made solutions for app back-end development. So, these reduce the overall development time, effort and cost, and make the overall process streamline. For instance, NPM includes approximately 8,00,000 built-in building block that developers can easily install and run smoothly.


Golang is available with a fully standard and a comprehensive library that includes features, which act independently of any third-party. And this is the actual reason why Golang includes a limited number of tools.



For deployment, Node.js requires installation of Node Package Manager (NPM) on the server or pulling down the application project code with pm2 on the server, in order to run it in the most effective way.


For app back-end development with Golang, there is certainly no requirement for locale. The binary, produced automatically from build, generally gets dropped automatically to server.

Community Support


Node.js is far ahead of Golang, when it comes to community support. It has a vast community consisted of numbers of distributors and also gets support from popular brands such as Microsoft, IBM, Intel, PayPal and others.


Golang has a small community with limited distributors. However, it is growing gradually year by year.

Final Words

It’s expected that you may have a clear understanding of the right technology for your app back-end development, after going through Node.js vs Golang 2019. In some sections, Node.js is leading over Golang and vice-versa. So, it would be a good idea to define your business requirements and choose the right technology that matches perfectly with the same.
