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.
