Migrating the Backend of My Real-Time Morse Code Website from Node.js to Go

I run a fairly advanced Morse Code translator website that allows users to convert text into Morse code and decode Morse messages back into readable text in real time. The platform includes interactive translation tools, Morse audio generation, downloadable outputs, educational resources, and optional message-sharing functionality. Most of the translation work currently happens in the browser using JavaScript, but I have also developed backend services for analytics, shared-message generation, API endpoints, and future expansion features. As traffic grows, I have started evaluating Go as a potential replacement for parts of my existing backend stack, and I would appreciate feedback from experienced Go developers regarding architecture and implementation best practices.

One of my primary concerns is determining which components of the application would benefit most from being rewritten in Go. The Morse Code translation itself is computationally lightweight, but the backend handles concurrent requests related to user-generated links, analytics collection, content delivery, and various asynchronous operations. I frequently hear that Go performs exceptionally well for network services and concurrent workloads, but I am unsure whether migrating a relatively small web application would provide meaningful benefits compared to the effort required to rewrite and maintain the codebase.

Another challenge involves designing the application’s concurrency model. Although individual Morse Code translations are simple operations, the website generates a large number of small requests from users interacting with real-time features. I am interested in understanding how Go developers would approach handling large volumes of lightweight requests, background jobs, and event processing. In particular, I would like advice on when to use goroutines, channels, worker pools, or message queues, and how to avoid creating unnecessary complexity while still taking advantage of Go’s concurrency capabilities.

I am also evaluating data storage and API design. The website may eventually support optional user accounts, saved translation histories, shared Morse messages, and educational progress tracking. Because of this, I am trying to determine how best to structure a Go backend that can evolve over time without requiring major architectural changes. I would appreciate recommendations regarding project structure, dependency management, database access patterns, and whether developers generally prefer keeping Go services monolithic for projects of this size or splitting functionality into smaller services from the beginning.

Performance and deployment considerations are another area where I am seeking guidance. One of the reasons I am interested in Go is the reputation for efficient memory usage, fast startup times, and straightforward deployment through static binaries. However, I am unsure how significant these benefits would be in practice for a Morse Code platform that is primarily frontend-driven. I would like to understand how developers typically monitor resource usage, benchmark performance, and determine whether a migration to Go is justified versus continuing to optimize an existing backend stack.

Finally, I would greatly appreciate advice from the Go community regarding the overall suitability of Go for an interactive educational web application like mine. For a Morse Code website that combines real-time user interactions, lightweight APIs, analytics collection, and future scalability requirements, what architecture would you recommend? Are there particular frameworks, libraries, project structures, or deployment strategies that have worked well for similar applications? Any insights into balancing simplicity, performance, maintainability, and long-term growth would be extremely helpful. Sorry for long post!

Is there anyone who can guide?

It’s hard to answer this from an external perspective. The complexity of your codebase plays a large role here. Are you currently experiencing any performance problems? Is your infrastructure prohibitively expensive?

For the most part, you probably won’t have to worry about concurrency too much based on what you are describing. Here’s why:

Each request will be processed on its’ own goroutine. So - you can block on that request until your processing is finished and it won’t slow anything else down. Where do you think concurrency that you have to manage would come into play?

I think most go devs would say “keep it as simple as possible and evolve over time”. Quote from RSC:

For example, the vast majority of packages in the Go ecosystem do not put the importable packages in a pkg subdirectory. More generally what is described here is just very complex, and Go repos tend to be much simpler.

Think about your package surface area / separation of concerns. But don’t over-think things like dependency injection. And yes - for a project of this size I would say a monolith is the way to go. There is not much to be gained from splitting things into separate microservices. And if you design your packages with separation of concerns, breaking things up is relatively easy in the future if/when you need to.

Just build a proof of concept that implements one route/solution/whatever and see how it performs. Also - benchmarking is a big part of the go community. TBH I rarely even have to think about performance in my Go apps. 99% of my bottlenecking happens at the DB layer for the apps I build. That or some weird front-end slowdown.

I mean - I think go is a good fit for this type of project. You won’t know what you don’t know until to try building something with it though. Like I said - I’d just start small and see what it feels like to build a Go app. And you can get better help/answers along the way if you post more scoped questions here once you start running in to problems.
