WebAssembly, also known as WASM, is a binary instruction format that provides multiple programming languages (C/C++, Ruby, Java, etc.) with a compilation target for smooth web processing. In this course, we’ll learn how to convert native code of different languages into WebAssembly and optimize it for better performance.

This intermediate-level course provides basic information on compilation techniques and VM infrastructure. It discusses converting C/C++ code into WebAssembly and loading the binary in a Node.js browser through tools like Emscripten and emsdk. You will learn the difference between WebAssembly text (WAST) and binary format (WASM). The course will cover step-by-step guidelines for switching between formats such as WASM, WAST, C, and JSON. Additionally, you’ll learn how to use tools provided by Binaryen.

After taking this course, you’ll learn how to integrate Rust into WebAssembly, publish modules, and optimize the memory model.

Practical WebAssembly

In this chapter, we’ll learn about Emscripten, which is a toolchain to convert C/C++ code into a WebAssembly module.

Emscripten consists of two components:


 


* Emscripten compiler frontend
