Smithy

The `smd!` macro provides an HTML-like template syntax similar to JSX, making it accessible for developers coming from React or similar frameworks, as shown in the simple counter example.

Leverages Rust's borrow checker to prevent common UI bugs at compile time, exemplified in the macro expansion where mutable and immutable borrows of state variables are handled separately to avoid conflicts.

Organizes app logic into clear phases like rendering, ref assignment, and event handling, ensuring predictable updates and enabling direct DOM manipulation via `post_render` callbacks.

After UI or window event callbacks are executed, Smithy automatically re-runs the app through phases, keeping the interface synchronized with state changes without manual intervention.
