If you have questions like:

- How has Node.js changed since the first edition of the book?
- Where do you see Node going in the next few years?
- Which patterns still hold up and which ones aged badly?

…this is the perfect time to ask them.

There’s a companion repo with all code samples (linked in the post). Stars are very appreciated ⭐
Feedback is golden — suggestions, critiques, and “why didn’t you cover X?” are most welcome!

I poured quite a few hours into making it concise, accurate, and example-driven. If it helps, please share it with a friend or colleague. 🙏

Need throughput and backpressure? We go into Streams with practical, copy-pasteable examples.
October 13, 2025 at 1:33 PM
Then we cover the limits of that approach and how to level up with fs.open() file handles for finer control.
October 13, 2025 at 1:33 PM
We start with the essentials: readFile() and writeFile() — and how to use them with async/await.

This guide assumes modern JavaScript: Promises + async/await, ESM, and top-level await.

No outdated patterns!

I looked for a clear, modern guide I could share… couldn’t find one that matches how we write Node.js today. So I wrote it.
