Collaboration platforms, video conferencing software, project management tools, and social media networks require real-time capabilities to facilitate seamless communication and interaction among users based in different geographic locations.
As there is every indication that all of these trends will continue throughout the coming years, it is highly likely that there will be more innovation and development in the field of real-time applications. Golang developers are poised to be at the forefront of this cutting-edge pursuit, particularly given that Golang possesses many features that make it an optimal choice for software applications - a topic we will explore in the next section.
Why Developers Use Golang For Real-World Application Development
Though a relatively new language, Golang has already earned an esteemed reputation for the ease with which it facilitates the building of real-world applications. In fact, according to the Go Developer Survey 2023 Results, Golang is considered a productive language for real-time application development, with high satisfaction rates among developers, especially those with less than one year of experience.
Here are the key advantages that makes Go programming language a suitable choice for real-world application developers:
Performance and Efficiency
Golang stands out for its relatively high speed and efficiency, making it a preferred choice for developers looking to build high-performance real-world applications. Its exceptional performance can be attributed to numerous elements, such as its swift compilation times and minimal memory usage. Considering Golang’s efficient and highly performative nature, it’s no wonder that companies like Google, Netflix, and Dropbox rely on the language for much of their real-world application development.
Another one of Golang’s distinctive qualities lies in its outstanding concurrency support. Real-world applications must be able to deal with multiple requests at the same time, and as Golang makes it straightforward for developers to write concurrent code, it is understandable that so many programmers opt for Go when creating real-world software.
Golang is able to achieve impressive levels of concurrency due to Goroutines, lightweight threads managed by the Go runtime. They are designed to allow developers to write concurrent code without the complexities associated with traditional threading. There are also channels to facilitate communication between Goroutines, thus simplifying the coordination between different parts of a program.
Simplicity and Readability
Many programmers praise Golang for its simplicity and readability. From beginner developers looking to expand their programming skills to experienced coders who are used to programming with Java or C++, Golang can be utilised by developers at all stages of their careers. Businesses looking to upskill their existing software development teams in a modern programming language are sure to be drawn to the user-friendliness and accessibility of Golang.
Golang's scalability makes it particularly well-suited for developing real-world applications. The language is designed to handle increased workloads by adding more nodes to distribute the load, a process facilitated by its built-in scalability support. This scalability makes it suitable for building systems that need to handle a high volume of concurrent requests, such as web servers and distributed systems. These attributes make it an ideal choice for building scalable real-time applications.
Rich and Varied Standard Library
Go comes with a comprehensive standard library that includes packages for networking, cryptography, JSON handling, and more. This standard library reduces dependencies on third-party libraries, ensuring a consistent and robust set of tools for developers.
As we can see, Golang has an array of exceptional features that make it an ideal option for developing real-time applications.

Best Practices for Developing Real-Time Applications in Golang
Whether you choose to upskill your programming team in Golang or choose to hire new developers with expertise in the language, one thing is for sure - with Golang developers at your organisation, you’ll have the opportunity to build efficient, user-friendly, and highly performant real-time applications that your users will appreciate.
However, before you decide to incorporate Golang into your real-time application development plan, it is crucial to gain an understanding of the techniques that your software developers will utilise when they power your real-time software. With this knowledge, your recruitment team will know what skills and competencies to look out for when it comes to recruiting top developers for your Golang jobs.
Here are 5 of the best practices that Golang developers follow when building real-time software:
1. Goroutines and Channels for Concurrency
Earlier, we alluded to the importance of Goroutines and Channels for Golang development. Goroutines are especially useful for creating efficient and concurrent applications, capable of handling multiple tasks concurrently and enabling asynchronous operations. Designed to communicate and share data without race conditions, Channels are routinely used in real-world applications to facilitate communication between Goroutines.
2. Graceful Shutdowns
Another technique that Golang developers typically utilise when creating real-time applications is ensuring graceful shutdowns. This process is important when handling shutdown events; by not following best practices, developers risk losing data or disrupting ongoing processes.
There are several practices to implement graceful shutdown mechanisms effectively, from stopping Goroutines and Channels to logging shutdown events. By managing graceful shutdowns correctly, developers can build resilient applications that can deal with shutdown events without compromising data integrity.
3. Error Handling
Employing error-handling methods is essential for creating applications in Golang. Without following the right error-handling procedures, the resilience and readability of the software may be diminished, thereby damaging user experience. To manage errors effectively, Golang developers must perform a range of crucial tasks, such as wrap errors with context, propagate errors, and test error scenarios. Properly handling errors throughout the application ensures that any potential failures will be well-managed without compromising the stability of the applications.
4. Security Measures
As with any piece of software, real-time applications are occasionally vulnerable to cyber threats. Golang developers must ensure that the application’s reliability and user-friendliness are not achieved at the expense of security, and there are various measures they can put into action to avoid security threats and vulnerabilities. These measures include encrypting sensitive data, following secure coding practices by avoiding hard-coded secrets, and continuously monitoring security-related events for potential threats.
5. Optimise Performance
Throughout the application development process, developers should routinely be looking for ways to optimise performance. When building real-time applications in Go, developers can leverage Golang’s built-in tools to ensure maximum efficiency. Utilising lightweight Goroutines for concurrent execution of tasks, managing memory by using Go’s garbage collection tool, and using built-in testing frameworks to simplify running tests are all methods that developers can employ to improve performance.
Building Real-World Applications in Golang: Key Takeaways
The demand for real-time software applications has surged, driven by evolving user expectations and technological advancements. With its exceptional performance and unique features, Golang has become a top choice for developers in crafting high-quality real-time applications.
