Mapbox File Sniff

Node module that returns spatial filetype.

Install

With npm:

npm install -g mapbox-file-sniff

Javascript example

var filesniffer = require('mapbox-file-sniff');
var buffer = fs.readFileSync('path/to/data/file.geojson');

filesniffer.sniff(buffer, function(err, filetype){
	console.log(filetype); // => 'geojson'
});

filesniffer.waft(buffer, function(err, protocol) {
  console.log(protocol); // 'omnivore:'
});

filesniffer.quaff('path/to/data/file.geojson', true, function(err, protocol) {
  console.log(protocol); // => 'geojson'
});

CLI example

$ mapbox-file-type path/to/data/file.geojson
# geojson
$ mapbox-file-protocol path/to/data/file.geojson
# omnivore:

• buffer: Buffer object of file contents (at least length 300)

• Zipped shapefile: zip
• Unziped shapefile: shp
• GPX: gpx
• KML: kml
• GeoJSON: geojson
• GeoTIFF: tif
• Mbtiles: mbtiles
• TileJSON: tilejson

waft(buffer, callback)

Returns a string for the following tilelive protocols:

• omnivore: tilelive-omnivore
• mbtiles: node-mbtiles
• tilejson: node-tilejson
• serialtiles: special case
• tm2z: tilelive-vector

quaff(filepath, protocol, callback)

A wrapper around waft and sniff that lets you pass in a file path (read as a buffer) and protocol to either return the protocol (waft) or the file type (sniff).
