Rust can now be used with WebAssembly (WASM) for frontend tasks like form validation, simplifying shared code between backend and frontend. A tutorial demonstrates building a Rust-powered web server with WASM form validation without heavy JavaScript toolchains.

Why it matters: Rust+WASM enables code reuse across frontend and backend, improving consistency and leveraging Rust’s safety and performance benefits.

The big picture: WASM adoption grows as tooling improves, reducing reliance on traditional JS frameworks and enabling Rust in web environments.

The stakes: WASM modules are larger than equivalent JS, which can increase load times and resource use for simple tasks like form validation.

Commenters say: Many feel WASM is overkill for form validation, preferring native JavaScript for lightweight tasks; others appreciate Rust’s unified tooling but note error handling and WASM size concerns.
