Instructor: 00:00 In order to get started, we need to install Rust using the installer, rustup. Introductions on how to set it up can be found on rustup.rs. If you are on OSX, you also can use brew install rustup. Then we run rustup-init.
00:26 Once we have Rust in our system, want to set the nightly toolchain as the default. We need to do this since currently only the nightly toolchain is supporting WebAssembly. Then we add the target wasm32-unknown-unknown.
00:43 Usually, you would add targets like x68_64-apple-darwin, specifying the target platform. Since WebAssembly is not compiled against any specific platform, these two values after the first dash are unknown and unknown.
01:23 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. wasm-gc is a tool to remove all unneeded exports, imports, functions, and so on from a WebAssembly module.
01:41 Last but not least, we need a web server. We use Cargo to install the HTTPS crate, shipping with the HTTP binary. It runs a web server, serving static files from the current directory, exactly what we need in our first couple lessons.
