    Build Status


    Render a map from a stylesheet:

    var mapnik = require('mapnik');
    var fs = require('fs');
    // register fonts and datasource plugins
    var map = new mapnik.Map(256, 256);
    map.load('./test/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');

    Convert a jpeg image to a png:

    var mapnik = require('mapnik');
    new mapnik.Image.open('input.jpg').save('output.png');

    Convert a shapefile to GeoJSON:

    var mapnik = require('mapnik');
    var ds = new mapnik.Datasource({type:'shape',file:'test/data/world_merc.shp'});
    var featureset = ds.featureset()
    var geojson = {
      "type": "FeatureCollection",
      "features": [
    var feat = featureset.next();
    while (feat) {
        feat = featureset.next();

    OS Node.js C++ minimum requirements OS versions
    Mac v0.10.x, v4, v5, v6 C++11 Mac OS X > 10.10
    Linux v0.10.x, v4, v5, v6 C++11 Ubuntu Linux > 16.04 or other Linux distributions with g++ >= 5 toolchain (>= GLIBCXX_3.4.21 from libstdc++)
    Windows v0.10.x, v4, v5 C++11 See the Windows requirements section

    An installation error like below indicates your system does not have a modern enough libstdc++/gcc-base toolchain:

    Error: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version GLIBCXX_3.4.21 not found (required by /node_modules/osrm/lib/binding/osrm.node)

    If you are running Ubuntu older than 16.04 you can easily upgrade your libstdc++ version like:

    sudo add-apt-repository ppa:ubuntu-toolchain-r/test
    sudo apt-get update -y
    sudo apt-get install -y libstdc++-5-dev

    To upgrade libstdc++ on travis (without sudo) you can do:

    language: cpp
    sudo: false
         - ubuntu-toolchain-r-test
         - libstdc++-5-dev # upgrade libstdc++ on linux to support C++11 


    Just do:

    npm install

    Note: This will install the latest node-mapnik 3.x series, which is recommended. There is also an 1.x series which maintains API compatibility with Mapnik 2.3.x and 2.2.x and a v0.7.x series which is not recommended unless you need to support Mapnik 2.1 or older.

    By default, binaries are provided for:

    On those platforms no external dependencies are needed.

    Other platforms will fall back to a source compile: see Source Build for details.

    Binaries started being provided at node-mapnik >= 1.4.2 for OSX and Linux and at 1.4.8 for Windows.

    Windows specific

    NOTE: Windows binaries for the 3.x series require the Visual C++ Redistributable Packages for Visual Studio 2015:

    See https://github.com/mapnik/node-mapnik/wiki/WindowsBinaries for more details.

    The 1.x series require the Visual C++ Redistributable Packages for Visual Studio 2013:

    Source Build

    To build from source you need:

    • Mapnik >= v3.0.10

    Install Mapnik using the instructions at: https://github.com/mapnik/mapnik/wiki/Mapnik-Installation

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

    Then run (within the cloned node-mapnik directory:

    make release_base

    Note on SSE:

    By default node mapnik is built with SSE support. If you are building on a platform that is not x86_64 you will need to disable feature by setting the environment variable SSE_MATH=false.

    SSE_MATH=false make

    Windows specific

    Windows builds are maintained in https://github.com/mapbox/windows-builds

    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


    To run the tests do:

    npm test
