api: WS gateway with token auth (Postgres-backed servers table, seeded via `bun run seed`), column-granularity chunk store (hand-written SQL migrations, no drizzle-kit CLI — its config loader needs esbuild, which doesn't install cleanly here), dirty-chunk Redis stream producer with per-flush dedup, and a tile-serving route. worker: consumes the dirty-chunk stream via a proper consumer group, rasterizes each chunk's columns into a single-resolution top-down PNG (static pre-Flattening block-id palette), uploads to MinIO, and upserts the tile pointer. frontend: barebones Leaflet 2D viewer (CRS.Simple, one native zoom level) wired to /api/servers and /api/tiles. Object storage: tiles live in a dedicated `mcmapper-tiles` bucket on the existing shared MinIO instance (devstack-minio on octo-winsrv) instead of a per-stack container, via a scoped access key limited to that one bucket — see README's "Object storage" section. MINIO_SECRET_KEY is real and is deliberately not committed; docker-compose layers an untracked .env over .env.example for it. Full pipeline verified end-to-end against live containers: WS auth -> Postgres upsert -> deduped Redis dirty-chunk event -> worker rasterize -> MinIO upload -> tile fetch through the api route, including from the actual mod-side WS client (see MCMapper-Mod's matching commit).

// Barebones Leaflet viewer (Phase 1). No auth/marker/chat UI yet — those are Phase 3/4.
|
|
//
|
|
// Tiles are one Minecraft chunk (16x16 blocks) each, upscaled to 256px, at a single native
|
|
// zoom level (see api's tile route + worker/src/render/cpu.rs) — Leaflet stretches that one
|
|
// native zoom to whatever zoom the user picks via `maxNativeZoom`/`minNativeZoom`.
|
|
//
|
|
// Coordinate mapping: Leaflet's CRS.Simple treats [lat, lng] as [y, x] with y growing upward
|
|
// on screen. Minecraft's Z grows south (visually "down" on a conventional north-up map), so
|
|
// tile y = -chunkZ here; the api negates it back to chunkZ when looking up the tile pointer
|
|
// (see api/src/index.ts's /api/tiles route comment).
