About the Book

WebAssembly in Action teaches you how to write and run high-performance browser-based applications using C++ and other languages supported by WebAssembly. In it, you'll learn to create native WebAssembly modules, interact with JavaScript components, and maximize performance with web workers and pthreads. And you'll love how the clearly organized sections make it a breeze to find the important details about every function, feature, and technique.

About the Technology

Write high-performance browser-based applications without relying only on JavaScript! By compiling to the WebAssembly binary format, your C, C++, or Rust code runs at near-native speed in the browser. WebAssembly delivers greater speed, opportunities to reuse existing code, and access to newer and faster libraries. Plus, you can easily interact with JavaScript when you need to.

What's inside

• Dynamic linking of multiple modules at runtime • Communicating between modules and JavaScript • Debugging with WebAssembly Text Format • Threading with web workers and pthreads

About the Reader

Written for developers with a basic understanding of C/C++, JavaScript, and HTML.
