"Server-Side WebAssembly" review

October 17, 2025

As a huge fan of WebAssembly (Wasm), I’ve been following its progress for a while now. I've written a number of articles about Wasm and even had the privilege of writing a book on the subject back in 2019 called "WebAssembly in Action".

WebAssembly can be difficult to keep up with because new features are constantly being proposed and implemented, there are a growing number of programming languages that support it, and the range of areas where it can be used keeps expanding.

I recently had an opportunity to read the book "Server-Side WebAssembly" by Danilo Chiarlone and I was pleasantly surprised by how much I learned.

The book’s practical examples walk you through creating WASI (WebAssembly System Interface) components from modules written in different languages. The book also explores some of the different ways that WASI components can be deployed ranging from standalone runtimes to Docker and Kubernetes.

I won’t spoil the book for you by giving away too many details but it’s worth the read to get a good, broad understanding of where and how the technology can be used outside the browser.

If you’re interested in learning more, the book can be found on Manning’s website here: "Server-Side WebAssembly"
