WebAssembly (WASM) for High Performance Apps · Lesson

Setting up Rust for WebAssembly

Configure your Rust development environment for WebAssembly targets and initialize a new WASM project.

Rust & WebAssembly Setup

Welcome! Rust is a fantastic language for building high-performance WebAssembly (WASM) modules.

Its focus on speed, memory safety, and control makes it ideal for web applications needing native-like performance.

In this lesson, we'll configure your environment and create your first Rust-WASM project.

Verify Rust & Cargo

Before we dive into WASM, ensure you have the Rust toolchain installed. This includes Rustc (the compiler) and Cargo (the package manager).

  • You can check by typing rustc --version and cargo --version in your terminal.
  • If not installed, visit rustup.rs to get rustup, the official Rust installer.
