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');

Note: to run these examples locally first do:

export NODE_PATH=./lib:${NODE_PATH}

For more sample code see 'examples/'


  • Node v0.6 or v0.8
  • Mapnik 2.x

Mapnik 2.1.0 is targeted, but 2.0.x is also supported.

This means that if you are running the Mapnik 2.1 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.

To install node-mapnik locally for development or testing do:

git clone git://
cd node-mapnik

Or set NODE_PATH to test importing:

export NODE_PATH=./lib
node -e "require.resolve('mapnik')"

Or you can also install via npm

npm install mapnik

The above will install node-mapnik locally in a node_modules folder. To install globally do:

npm install -g mapnik

Quick rendering test

To see if things are working try rendering a world map with the sample data

From the source checkout root do:

export NODE_PATH=./lib
node ./examples/simple/render.js ./examples/stylesheet.xml map.png

Using node-mapnik from your node app

To require node-mapnik as a dependency of another package put in your package.json:

"dependencies"  : { "mapnik":"*" } // replace * with a given semver version string


See the 'examples/' for more usage examples.

For some of the examples you will need:

npm install generic-pool
npm install get


To run the tests do:

npm test

Or you can manually install mocha and then just do:

make test
