First, you'll need Rust. To install Rust and the
cargo build tool, follow the official instructions.
You also need to install the
wasm32-unknown-unknown target to compile Rust to Wasm.
If you're using rustup, you just need to run
rustup target add wasm32-unknown-unknown.
The minimum supported Rust version (MSRV) for Yew is
1.45.0. Older versions can cause unexpected issues accompanied by incomprehensible error messages.
You can check your toolchain version using
rustup show (under "active toolchain") or alternatively
rustc --version. To update your toolchain, run
Wasm Build Tools
depending on the tool you choose, they can help make deployment and packaging much less of a
binary in a browser.
A tool practically made for building Yew apps.
It can build any
wasm-bindgen based app and its design is inspired by rollup.js.
It can bundle assets for your app and even ships with a Sass compiler.
All of our examples are built with Trunk.
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
Because of this, it can only build libraries and doesn't provide useful tools like a development server or automatic rebuilds.
This was the best preferred tool to use before the creation of
