I built zsweep because I wanted a Minesweeper experience that respected "Vim grammar" rather than just mapping arrow keys to HJKL. I found that using a mouse for grid navigation broke my flow state during quick breaks, so I engineered this to be 100% keyboard-centric.
Technical Highlights:
Vim Grammar Engine: I implemented a custom state machine to handle complex motions. This includes quantifiers (e.g., 5j), search (pressing / plus a number to jump to that digit), and context-aware word motions (w/b) that intelligently skip over revealed safe cells to land on unrevealed ones.
Svelte 5 & Performance: Built with SvelteKit using the new Svelte 5 runes. This was critical for ensuring zero-latency input handling—if the movement doesn't feel as snappy as a native terminal, the "Vim feel" is lost.
Backend & Stats: Powered by Supabase. I recently had to refactor the global stats dashboard to move from client-side counting to server-side aggregation (RPC). I hit a common "gotcha" where standard selects were capping at 1,000 rows, causing our total time sweeping to drift. It now correctly reflects our full database aggregate.
Security: Leveraging Row Level Security (RLS) policies to ensure users can only modify their own game results while keeping the global leaderboard public.
Why I'm Sharing Today:
We recently hit 1,000+ active users, and I’m looking for technical contributors to help polish the experience. I’ve opened issues on GitHub regarding sound system customization and performance optimizations for the larger 30x16 grids.
