Wasm Build Tools
Wasm Build Tools
Extra tooling is needed to facilitate the interop between WebAssembly and JavaScript. Additionally,
depending on the tool you choose, they can help make deployment and packaging much less of a
headache by generating all of the JavaScript code necessary to load and run your app's .wasm
binary in a browser.
trunk
A tool practically made for building Yew apps.
It can build any wasm-bindgen
based app and its design is inspired by rollup.js.
With Trunk you don't need to have Node.js installed or touch any JavaScript code for that matter.
It can bundle assets for your app and even ships with a Sass compiler.
All of our examples are built with Trunk.
wasm-pack
A CLI tool developed by the Rust / Wasm Working Group for packaging up WebAssembly. Best used
together with the wasm-pack-plugin
for Webpack.
The primary purpose of wasm-pack
is building Wasm libraries for use in JavaScript.
Because of this, it can only build libraries and doesn't provide useful tools like a development server or automatic rebuilds.
