The egui web UI at /egui rendered blank due to missing WASM artifacts and lacking visual style initialization.

Changes

  • crates/server/src/web/app.rs: Added configure_style() to initialize dark theme, text sizes (14px/20px), and rounded corners matching desktop implementation
  • crates/server/ui/egui/README.md: Documented build process, architecture, and code reuse patterns
  • build-egui-web.sh: Clarified build instructions

Implementation

fn configure_style(ctx: &egui::Context) {
    ctx.set_visuals(egui::Visuals::dark());
    
    let mut style = (*ctx.style()).clone();
    style.text_styles.insert(
        egui::TextStyle::Body,
        egui::FontId::new(14.0, egui::FontFamily::Proportional),
    );
    // ... rounded corners, etc.
    ctx.set_style(style);
}

Build & Usage

./build-egui-web.sh                # Compiles to WASM (~1.3 MB) + JS bindings (76 KB)
cargo run -- daemon start          # Serves at :31327
# Navigate to http://localhost:31327/egui

The PoC demonstrates egui code reuse between native desktop and WASM web with minimal platform-specific adjustments. Current implementation shows mock chat interface; backend integration remains future work.

Notes

WASM artifacts are gitignored and must be built locally. The web UI structure mirrors the desktop DesktopApp for consistency.
