BackendApi and commands

Area	Frontend methods	Tauri command or capability
Games	getGameById, getGamesList, addGame, updateGame, deleteGame	matching snake_case commands
Metadata	getAllGenres/Developers/Publishers/Tags	matching get_all_* commands
Launch	launchGame, detectLocaleEmulator	launch_game, detect_locale_emulator
Selection	selectExecutableFile, selectFolder, selectImageFile	dialog plugin
External	openExternalLink, openFolder	opener plugin
Images	processGameImage, finalizeGameImages, cleanupTempImages	matching commands
Settings	getSettings, saveSettings	settings_get, settings_save
Statistics	eleven stats/session methods	commands in stats_manager

Statistics covers recent game days, game date ranges, week-by-date, daily sessions, monthly daily totals, yearly daily totals, overall totals, top games, monthly summaries, recent sessions, and launch methods. Dates use YYYY-MM-DD, timestamps use milliseconds, and durations use seconds.

Events

Event	Main payload	Purpose
game-store-changed	action, optional game	Refresh after CRUD
game-launched	gameUuid	Mark a game running
game-session-ended	UUID, session ID, duration, total, start/end	Refresh valid-session data
game-stopped	gameUuid	Clear running state, including invalid sessions

Every subscription returns an unsubscribe callback; components must call it during unmount.

Known limitations and checklist

• Shortcut creation, game information, save backup, and Script remain placeholders.
• File parameters are absent from LaunchParams; Play selects only the first File action.
• Folder monitoring is the best-maintained mode.
• A new feature must update all three locale files, BackendApi, command registration, both user guides, both developer guides, and relevant screenshots.
• Before release, run the frontend build, Rust test/fmt, VuePress build, and a bilingual structure check.
