The **mbtiles‑reader** package provides a tiny, cross‑environment library for opening an MBTiles SQLite file and extracting its tiles and metadata. It works both in Node.js (via better‑sqlite3) and in browsers (via the SQLite‑Wasm module), letting developers read individual XYZ tiles, iterate over all tiles, or query the MBTiles metadata directly from a file path, Buffer, `File`, or OPFS handle. It’s aimed at web‑mapping developers who need a simple, type‑safe way to consume MBTiles datasets in client‑side or server‑side JavaScript.
