Node.js vs Golang — Which Is Best for Your Project?
It’s challenging for companies and engineers to choose the perfect tech stack for their next project. Especially for backend development — it’s all about building and scaling APIs, libraries, data management, and less-user-facing code.
This article will compare Node.js vs Golang and help you decide better by outlining the pros and cons of both. We’ll also mention the top companies and apps using them. Lastly, we’ll compare each language based on performance, scalability, error handling, availability of developers, and the average salary for each programming language.
What Is Node.Js?
What Is Golang?
The first release of Golang was in 2009, the same as Node.js. Golang, also known as Go, is an open-source, statistically typed, multi-purpose, cross-platform, compiled, and fast programming language developed by the engineers at Google to solve specific problems by combining the strength and eliminating the weaknesses of other programming languages.
Go is a high-efficiency programming language with similarities to the C programming language regarding speed and syntax. Go is a straightforward and clear programming syntax for writing readable and maintainable code.
Golang is also a structural language with an adequate handling of concurrent programming, with excellent garbage collection handling, dynamic interfaces, and built-in memory safety.
Golang averaged the 13th position of most popular programming languages and was the Programming Language of the Year in 2009 and 2016. The 2019 Stack Overflow Developer Survey shows that Go is the 13th most popular technology overall.
What Is Node.Js Used For?
Node.js is an excellent choice for creating an actual time application with two-way connections where the server doesn’t wait for an API to return data.
What Is Golang Used For?
Golang is a multi-purpose programming language you can use to create various applications, including highly modular application systems focused on security and speed.
Most importantly, you can use Golang for system programming, large-scale distributed systems, and highly scalable network applications and servers. It also finds use in cloud-based development, web app development, and big data or machine learning applications.
Pros and Cons of Node.Js
Next, we will explore the pros and cons of Node.js to give you a better understanding of the language.
- Used to build scalable web applications
- Works very well with the NoSQL database MongoDB
- Used to create highly performant applications because of the Event loop feature built-in
- Has the fastest growing community, with features and packages coming out daily
- It makes caching individual modules a breeze and encourages fast application.
- It uses asynchronous programming, which seems advantageous, but it requires a high level of expertise to master to create a scalable application.
- In Node.js, many APIs and packages undergo frequent changes and updates, which cause compatible issues and confuses the developers.
Pros and Cons of Golang
Next, we will explore the pros and cons of Golang to give you a better understanding of Golang.
- Simple to maintain apps since the code is easy to read
- Popular with developers because it features a neat and clean syntax
- Google actively supports the development of Golang. It’s the official language used at Google to build all the giant projects, and as such, it receives all the support it needs.
- Since Golang is statically typed, language developers are less prone to making variable errors.
- Go alerts you when you write a program without appropriate documentation
- Significant performance gains due to being a compiled language (interpreted languages are a bit slower)
- APIs available to test and stretch code
- Static code analysis using GoMetaLinter, a handy tool
- Concurrency supported, which helps programmers to build systems with a high degree of parallel processing
- Developers need to code more to implement a simple feature in Golang (complex abstractions aren’t provided; while that makes Go a simple language to use, it limits its versatility)
- Code reusability is more difficult in Go than in other languages since Go doesn’t support generics.
- It doesn’t offer a built-in GUI library for building GUI applications (this defect means that you will need to spend significant effort to connect a library with your project)
- The community has less maturity compared to some other leading programming languages.
- Go consumes more computing resources for complex programs — such programs have substantial file sizes since Go doesn’t have a virtual machine (VM)
Companies and Apps Using Node.Js

Companies and Apps Using Golang
Below is the list of companies and applications using Golang actively on their server:
Comparison of Node.Js vs. Golang
Performance is an integral part of every scalable system, and that’s why developers love Node.js. To illustrate, here are some of the best applications developed using Node.js. In addition to gaining performance through caching, let’s compare Node.js vs. Golang, the former of which processes faster in terms of sheer speed.
Golang developers stress that Go’s performance is the same as C and C++, which is great because Go compiles its codes directly to machine code without any virtual machine to slow down the compilation process.
There is also a built-in garbage collector in Golang that automatically frees up unused memory spaces, increasing available memory for faster processing. This feature also lowers the risk of security vulnerabilities due to memory leakage.
Statically typed Node.js with TypeScript is generally slower than other programming languages. Unlike Go, Node.js cannot offer CPU and memory-bound tasks performance, meaning that the version of Node.js cannot be as specific — it can perform great or terribly depending on the nature of the app.
In this performance comparison, Go surpasses Node.js regarding how fast a programming language should perform and how quickly it should compile and execute instructions.
Scalability and Concurrency
Google intended to develop a programming language for building heavy and complex enterprise-scale, production-ready applications in terms of scalability. They defined scalability as their top priority, and they did achieve it.
Go uses goroutines, which allows reliable and easy execution of threads and can be performed concurrently in a smooth manner. These goroutines make Go a perfect scalable programming language.
In Node.js single-threaded architecture, CPU-bound tasks sometimes block the event loop and slow down your program. As a result, you get a slow app and annoyed users.
In this comparison, it’s clear that Go surpasses Node.js because it allows concurrency through goroutines, which results in faster processes than Node.js single-threaded architecture.
Sometimes, you can determine the best tool or language by running through different tasks or algorithms and calculating the time, speed, etc., it takes each language to perform.
Below, we’ll look at an example that shows the benchmark task performance of Node.js vs. Go for different computer language methods and algorithms.
From the statistics above, we can observe that Golang takes less time, memory, and CPU load to perform operations than Node.js.
Node.js traditionally handles errors using the try-catch technique of handling exceptions, where errors are caught just when they occur, and developers can debug errors quickly and faster.
Golang separates compile-time and runtime errors differently. This inconsistency causes confusion between developers and has led to a standard process in handling exceptions.
However, Go developers think there will be more improvements on the language with the upcoming Go 2 version, including better error handling, error values, and generics.
For now, though, it’s clear that Node.js surpasses Golang in handling errors and exceptions properly.
Golang requires developers to learn its specific processes, concepts, rules, pointers, strict typing, interfaces, coroutines, and much more. Golang developers typically face a steeper learning curve.
Most importantly, Golang is a backend programming language only. Therefore, you need to hire a frontend developer separately.
From the comparison, it’s clear that Node.js has a lower learning curve compared to Golang.
Open-source projects are known for the large numbers of developers contributing daily and the large community backing the projects. Both Node.js and Golang are open source with extensive developer support and communities.
Node.js, on the one hand, is the more mature tool with strong and larger community backings. The Node.js Foundation enables widespread adoption of Node.js; a team of professionals oversees the security and long-term support (LTS) plan for improved stability of Node.js.
GoDaddy, Intel, IBM, Microsoft, PayPal, and NodeSource are active members of the Node.js Foundation and Node+JS Interactive, where developers announce new improvements and change Node.js.
Node.js has 80,300 Github Stars and over one billion downloads of Node.js as of the time of writing.
Golang, on the other hand, has a smaller community and keeps growing every day. Google’s support for Go and hosting the GopherCon, which gathers Go developers worldwide to discuss new opportunities and changes annually, offers a reason to migrate to Golang.
Everyone will agree that the availability of libraries and tools for every task and project cuts down development time and cost.
NPM alone consists of approximately 800,000 ready-made tools for any particular case, and many others not published yet are nearing viability.
Golang is barely new into the backend development ecosystem, and although they’re great tools for solving specific tasks, there aren’t as many as Node.js.
From our comparison, it’s clear that Node.js has more available development tools than Golang, simply because it’s for both the frontend and backend.
Salary and Availability of Developers
Finding Go developers can be difficult as the language is brand new, but it is among the most promising, with a bright future ahead.
In terms of salaries for each technology, let’s look at Stackoverflow Survey 2020.
Golang pays very high because of the scarcity created as a new and promising programming language:
You can also see the comparison in the United States.
From the comparison, it is clear that Node.js has more available developers and jobs than Golang, but Golang pays more than Node.js.
From the analysis above, it’s challenging to choose which technology is better. We’ve attempted to give you insights into which technology will best fit your project or align appropriately with your company’s culture and processes.
