Restyle the idle watcher loading UI with design tokens, light and dark
variants via `prefers-color-scheme`, and system font stacks (drop
Google Fonts). Tighten layout, animations, and console presentation.
In `loading.js`, pass event `level` into `addConsoleLine` and apply
`level-*` classes so log lines can reflect debug, info, warn, and
error. On the HTML side, set `color-scheme`, add an empty `alt` on the
logo, and mark the loading dots as `aria-hidden` for assistive
technology.
This refactor replaces the custom event broadcasting implementation with the centralized goutils/events package across idlewatcher.
The changes include simplifying the WakeEvent struct, removing manual SSE channel management, and adopting a cleaner event history pattern.
The frontend JavaScript has been updated to work with the new event format.
This major overhaul of the idlewatcher system introduces a modern, real-time loading experience with Server-Sent Events (SSE) streaming and improved error handling.
- **Real-time Event Streaming**: New SSE endpoint (`/$godoxy/wake-events`) provides live updates during container wake process
- **Enhanced Loading Page**: Modern console-style interface with timestamped events and color-coded status messages
- **Improved Static Asset Management**: Dedicated paths for CSS, JS, and favicon to avoid conflicting with upstream assets
- **Event History Buffer**: Stores wake events for reconnecting clients and debugging
- Refactored HTTP request handling with cleaner static asset routing
- Added `WakeEvent` system with structured event types (starting, waking_dep, dep_ready, container_woke, waiting_ready, ready, error)
- Implemented thread-safe event broadcasting using xsync.Map for concurrent SSE connections
- Enhanced error handling with detailed logging and user-friendly error messages
- Simplified loading page template system with better asset path management
- Fixed race conditions in dependency waking and state management
- Removed `common.go` functions (canceled, waitStarted) - moved inline for better context
- Updated Waker interface to accept context parameter in Wake() method
- New static asset paths use `/$godoxy/` prefix to avoid conflicts
- Console-style output with Fira Code font for better readability
- Color-coded event types (yellow for starting, blue for dependencies, green for success, red for errors)
- Automatic page refresh when container becomes ready
- Improved visual design with better glassmorphism effects and responsive layout
- Real-time progress feedback during dependency wake and container startup
This change transforms the static loading page into a dynamic, informative experience that keeps users informed during the wake process while maintaining backward compatibility with existing routing behavior.
