Holy crap, it's Mapnik running on Heroku! This is a quick implementation of node-mapnik's default example, running on Heroku with very little configuration. Epic thanks to Dane Springmeyer for going above and beyond.
This application uses node-mapnik-heroku to render a simple map using Mapnik on Heroku. This changes everything.
Once you have it pushed to Heroku, just set the following environment variable:
$ heroku config:add LD_LIBRARY_PATH=/app/node_modules/mapnik/libThe mapnik binaries have been precompiled and included in the node-mapnik-heroku module. This is a little known feature of Heroku.
