CS Weekly Drop Reset

A plugin that adds a live countdown to the next Counter-Strike weekly drop reset, right on the Counter-Strike 2 page in your Steam library. It mounts a native-looking tile into the play bar's stats row, so it blends in with Steam's own UI.

Features

• Live countdown to the next weekly drop reset, updated every second.
• Native styling — reuses Steam's own play-bar classes so the tile looks built-in.
• Hover tooltip with the reset schedule and the exact reset time in your local timezone.
• Click through to a detailed drop-reset info page.
• Lightweight & frontend-only — no backend, no network calls, no telemetry.

Drop reset schedule

Counter-Strike weekly drops reset every Wednesday at 01:00 UTC. The tile shows the remaining
time as Dd HH:MM:SS (the day count is omitted in the final 24 hours), and the tooltip translates
the next reset into your local time.

Localisation & Languages

The plugin respects your Steam client language settings. It fully translates all titles, labels, countdown units (day/hour/minute/second), and date formats for the following 10 languages:

• English (default)
• Chinese (Simplified & Traditional)
• Russian
• German
• Spanish
• French
• Japanese
• Korean
• Portuguese (Brazilian)

How it works

Steam's library uses an in-memory React router, so the URL never reflects the current page. The
plugin watches each Steam window (via AddWindowCreateHook) and detects the Counter-Strike 2 page
by locating the visible play-bar game-name element, then mounts a React tile into that page's stats
section. Navigation is tracked through history hooks, popstate/hashchange, a debounced
MutationObserver, and a 1-second polling fallback. Tiles are unmounted cleanly when you leave the
CS2 page.
