Defer heavy tool auto-install checks from startup to first-use paths to avoid long launch stalls, and merge backend queue snapshots with in-flight renderer progress state so download status text no longer jumps between placeholder states.
Download and extract streamlink/ffmpeg dependencies into ProgramData when unavailable so fresh server installs can start downloads without manual tool setup, while preserving detailed debug logging for failures.
Resolve streamlink execution more robustly by trying direct binary and Python module launchers, then return actionable error messages when streamlink is missing on server environments.
Keep queue visibility synced while downloads run, show richer per-item progress/error states in the sidebar, and write backend downloader diagnostics to ProgramData debug.log so instant start/stop failures can be traced on user systems.
Allow streamer/VOD browsing without Twitch credentials via public GraphQL fallback, harden queue visibility by syncing renderer state with backend updates, and ship a comprehensive Astro/MDX documentation set similar to established downloader projects.
Use a safe path join for ffprobe instead of broad string replacement so video info, cutter duration, and merge duration checks work reliably on Windows installations.
Move streamer, queue, settings and update logic into dedicated renderer files, introduce shared type declarations, and remove ts-nocheck so the UI codebase can continue migrating toward a maintainable TypeScript-first structure.
Move inline UI logic into a dedicated TypeScript renderer file and extract CSS into a standalone stylesheet to continue the migration away from monolithic HTML and toward a TS-first structure.
Complete rewrite using modern web technologies:
- Electron for cross-platform desktop app
- TypeScript for type-safe code
- Modern UI with multiple themes (Twitch, Discord, YouTube, Apple)
Features:
- VOD browsing and download with Streamlink
- Clip downloader
- Download queue with persistence
- Settings management
- Auto-update support
