Minimizing the WebAssembly Modules

Learn how to minimize the size of WebAssembly modules using optimization levels with wasm-opt.

We'll cover the following

wasm-bindgen is a complete suite that generates the binding JavaScript file (along with polyfills) for the WebAssembly module. In previous chapters, we saw how wasm-bindgen provides libraries and makes it easy to pass complex objects between JavaScript and WebAssembly. But in the WebAssembly world, it’s important to optimize the generated binary for size and performance.

Getting started with a project

Let’s see how we can further optimize the WebAssembly modules:
