What I Learned Moving from Node to Go: 7 Challenges, 7 Solutions

A practical guide for JavaScript/Node.js developers transitioning to backend Go.

Switching from Node.js to Go isn’t just about syntax - it’s a whole mindset shift. The way you structure your code, handle errors, manage concurrency, and even think about unit testing completely changes.

💡 What’s inside:

• Structure of go code - and why it works
• Practical logging and error handling techniques
• Dependency injection put in practice with examples
• How does the above help unit test the most important parts of your code
• Things I wish I knew before switching from the JavaScript land

👨‍💻 I’m a senior backend engineer at a global tech company, and I'm also passionate about cybersecurity playing CTFs. I've seen both performance and security challenges firsthand - and Go has changed how I approach both.

If you’re a JavaScript or Node developer ready to dive into Go without wasting weeks on trial and error (like I did), this is a shortcut for you!
