Bindings to Mapnik for node.


Render a map synchronously:

var mapnik = require('mapnik');

var map = new mapnik.Map(256, 256);

Render a map asynchronously:

var mapnik = require('mapnik');
var fs = require('fs');

var map = new mapnik.Map(256, 256);
map.load('./examples/stylesheet.xml', function(err,map) {
    if (err) throw err;
    var im = new mapnik.Image(256, 256);
    map.render(im, function(err,im) {
      if (err) throw err;
      im.encode('png', function(err,buffer) {
          if (err) throw err;
          fs.writeFile('map.png',buffer, function(err) {
              if (err) throw err;
              console.log('saved map image to map.png');

For more sample code see


  • Node >v0.6.13 and < v0.11
  • Mapnik 2.x

Mapnik 2.2.x is targeted, but 2.1.x and 2.0.x are also supported.

This means that if you are running the Mapnik 2.2 series (current unreleased master) you must be running at least 0eddc2b5a0.

This means that if you are running the Mapnik 2.0.x series some minor test failures are expected:

  • 6-7 test failures are expected using Mapnik 2.0.0
  • 4-5 test failures are expected using Mapnik 2.0.2
  • 0 test failures are expected using Mapnik 2.1.0-pre


First install Mapnik - for more details see:

Confirm that the mapnik-config program is available and on your $PATH.
