In order to setup a project we need to install the nightly build of Rust and add the WebAssembly target. For an improved workflow we also install the CLI tools wasm-pack and wasm-gc.

 

Install:

brew install rustup

 

Run:

rustup-init

 

Setup nightly toolchain as default.

rustup default nightly

 

Then we add the target wasm32-unknown-unknown

rustup target add wasm32-unknown-unknown

 

In addition, we use cargo, Rust's package manager, to install wasm-pack

cargo install wasm-pack

This tool seeks to be the one-stop shop for building and working with Rust-generated WebAssembly that you would like to interop with JavaScript in the browser or with Node.js.

 

For the first couple lessons, we don't use wasm-pack. Instead, we're going to use a tool called wasm-gc. We install it.

cargo instal wasm-gc

wasm-gc is a tool to remove all unneeded exports, imports, functions, and so on from a WebAssembly module.

 

Install HTTPS server:

cargo install https
