Dashboard fetching data via async Rust back-end
Form validation and submission with reactive UI
Real-time updates via WebSockets
SSR for SEO-friendly landing pages
Troubleshooting
Ensure correct Rust toolchain version
Check Cargo.toml dependencies for compatibility
Verify wasm-pack or cargo-leptos build process
Inspect browser console for WebAssembly errors
Debug SSR rendering using server logs
Testing Guide
Unit test Rust components with `cargo test`
Test client-side Wasm with wasm-bindgen-test
Use browser dev tools for UI inspection
