Server-Side WebAssembly lays out everything you need to take WebAssembly beyond its traditional browser domain. You’ll put on the hats of a systems architect, a backend developer, and even a DevOps engineer to get a full picture of WebAssembly development from both an architecture and development perspective.
Danilo Chiarlone
Server-Side WebAssembly by Danilo Chiarlone is officially out. If you’ve been watching WebAssembly creep beyond the browser and wondering what it actually looks like in a production backend, this book lives right there.
Solomon Hykes sums up the direction well:
“WebAssembly on the server is the future of computing.”
Danilo doesn’t treat that as a slogan. He walks through how server-side Wasm works in practice—starting from the fundamentals and moving quickly into real systems. You build a working backend with HTTP handling, data storage, and even AI-generated content, while seeing how Wasm components fit together across different languages and runtimes.
Some of what the book digs into:
-
Building and deploying server-side Wasm apps
-
Creating and running Wasm containers with OCI
-
Compiling components from more than one language
-
Running Wasm workloads on Kubernetes
-
Shipping the same app across environments without rework
-
Connecting to databases and ML systems
One thing we liked during development is the range of perspectives it covers. You’re not just writing code—you’re thinking like an architect, a backend dev, and a DevOps engineer, sometimes all in the same chapter. That mirrors how most of us actually work.
If WebAssembly has been on your radar but you haven’t seen a clear path from “interesting tech” to “this runs in prod,” this book aims to close that gap.
