You will find some prototypes and testing code in /testing that shows how you can render data from a PostGIS database.
You will need a running Postgres database with PostGIS and pgRouting installed and have some data imported.
OSM data extracts can be obtained from bbbike.
A nice tutorial on how to install pgRouting and prepare the data for import can be found on the ZevRoss blog.
We are providing a Dockerfile that you can check out. You will also need a database populated with OSM and Pgrouting data.
