In the first definitive guide on WebAssembly, you'll learn how you can wield this new technology to break through the current barriers of web development and build an entirely new class of performant applications .

Key Features

 • Generate WebAssembly modules from C and C++ using Emscripten and interact with these modules in the browser 

 • 

 • Learn how to use WebAssembly outside of the browser and load modules using Node.js 

 • 

 • Build a high-performance application using C and WebAssembly and port an existing C++ game to WebAssembly using Emscripten 

 • 

Book Description

WebAssembly is a brand-new technology that represents a paradigm shift in web development. This book teaches programmers to leverage this technology to write high-performance applications that run in the browser. This book introduces you to powerful WebAssembly concepts to help you write lean and powerful web applications with native performance. You start with the evolution of web programming, the state of things today, and what can be done with the advent and release of WebAssembly. We take a look at the journey from JavaScript to asm.js to WebAssembly. We then move on to analyze the anatomy of a WebAssembly module and the relationship between binary and text formats, along with the corresponding JavaScript API. Further on, you'll implement all the techniques you've learned to build a high-performance application using C and WebAssembly, and then port an existing game written in C++ to WebAssembly using Emscripten. By the end of this book, you will be well-equipped to create high-performance applications and games for the web using WebAssembly.

What you will learn

 • Learn how WebAssembly came to be and its associated elements (text format, module, and JavaScript API)

 • 

 • Create, load, and debug a WebAssembly module (editor and compiler/toolchain)

 • 

 • Build a high-performance application using C and WebAssembly

 • 

 • Extend WebAssembly's feature set using Emscripten by porting a game written in C++

 • 

 • Explore upcoming features of WebAssembly, Node.js integration, and alternative compilation methods

 •
