This is a fork of @mapbox/mbtiles.

Installation

npm install @mapwhit/mbtiles

const MBTiles = require('@mapwhit/mbtiles');

API

Constructor

All MBTiles instances need to be constructed before any of the methods become available. NOTE: All methods described below assume you've taken this step.

const mbtiles = new MBTiles('./path/to/file.mbtiles');
console.log(mbtiles) // mbtiles object with methods listed below

Reading

getTile(z, x, y)

Get an individual tile from the MBTiles table. This can be a raster or gzipped vector tile. Also returns headers that are important for serving over HTTP.

const { error, tile, headers } = mbtiles.getTile(z, x, y);
// `tile` is your gzipped buffer - use zlib to gunzip or inflate

getInfo()

Get info of an MBTiles file, which is stored in the metadata table. Includes information like zoom levels, bounds, vector_layers, that were created during generation. This performs fallback queries if certain keys like bounds, minzoom, or maxzoom have not been provided.

const info = mbtiles.getInfo();
