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.

Then we cover the limits of that approach and how to level up with fs.open() file handles for finer control.

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No outdated patterns!

Here’s a story I didn’t expect to write 👇🧵 (1/8)

A few days ago I went down a rabbit hole to see what people search most about Node.js. Guess what? “how to read and write files” is near the top.

Cover art for “Reading and Writing Files in Node.js,” featuring a cartoon version of Luciano. On the left, he’s writing on paper with a pen; on the right, he’s reading a newspaper with a focused expression. The illustration visually represents the concepts of writing and reading files in Node.js.

Level up from dev → architect?

Check out James’s latest Dometrain course: modular monoliths, events, C4, observability, ADRs.

Even if you’re not into .NET, you'll get tons of value from it! 🚀

James Eastham @jameseastham.co.uk · 6d

Excited to announce my new course on Dometrain - Solution Architecture Deep Dive.

The #1 feedback I got on the first course was the depth. Don't worry, this ones goes deeper. Deeper into what it actually means to be an architect in 2025.
