WebAssembly fulfills the long-awaited promise of web technologies: fast
code, type-safe at compile time, execution in the browser, on embedded
devices, or anywhere else. Rust delivers the power of C in a language
that strictly enforces type safety. Combine both languages and you can
write for the web like never before! Learn how to integrate with
JavaScript, run code on platforms other than the browser, and take a
step into IoT. Discover the easy way to build cross-platform
applications without sacrificing power, and change the way you write
code for the web.
WebAssembly is more than just a revolutionary new technology. It's
reshaping how we build applications for the web and beyond. Where
technologies like ActiveX and Flash have failed, you can now write code
in whatever language you prefer and compile to WebAssembly for fast,
type-safe code that runs in the browser, on mobile devices, embedded
devices, and more. Combining WebAssembly's portable, high-performance
modules with Rust's safety and power is a perfect development
combination.
Learn how WebAssembly's stack machine architecture works, install
low-level wasm tools, and discover the dark art of writing raw wast
code. Build on that foundation and learn how to compile WebAssembly
modules from Rust by implementing the logic for a checkers game. Create
wasm modules in Rust to interoperate with JavaScript in many compelling
ways. Apply your new skills to the world of non-web hosts, and create
everything from an app running on a Raspberry Pi that controls a
lighting system, to a fully-functioning online multiplayer game engine
where developers upload their own arena-bound WebAssembly combat
modules.
Get started with WebAssembly today, and change the way you think about
the web.
What You Need:
You'll need a Linux, Mac, or Windows workstation with an Internet
connection. You'll need an up-to-date web browser that supports
WebAssembly. To work with the sample code, you can use your favorite
text editor or IDE. The book will guide you through installing the Rust
and WebAssembly tools needed for each chapter.
