This is just a simple Mapbox GL Native server example written in Node.js using Express. The server has a single endpoint that takes z, x and y and renders a png image tile based on the configured base vector tiles.
Run npm install to install all dependencies.
NOTE: The mapbox-gl-native package requires that you're using node version 4.X.
Update the values in "config.js" to match you configuration and run npm start to start the server.
You can then go to http://localhost:3000/0/0/0/ to see the whole World rendered at "the left top corner" of the tile source (or something else, depending on your vector map source).
