welcome

Throughout this book, you will put on many hats—one of a systems architect, one of a backend developer, and one of a DevOps engineer—all to give you the full picture of WebAssembly development beyond its innate browser domain.

The book is divided into two parts. Part 1 explores WebAssembly from an architect's perspective, covering building applications with Wasm modules, enhancing portability and security with components, interfacing with underlying systems, and exploring applications from machine learning to databases. Part 2 focuses on the developer experience, teaching you how to create production-grade Wasm applications, work with Wasm containers using Docker, and ensure scalability with Kubernetes integration. By the end of it, you should know how to develop and deploy WebAssembly all the way to the edge.

As you read Server-side WebAssembly, you will learn by doing. Topics are frequently explained via example, and throughout the book, we will work on a big project, progressively building on it with each new skill you acquire.
