A final example of our pgRouting journey is a web application that consumes some of the functionality we have seen so far.
In order to preview the example, navigate to the example's folder - apps/pgrouting, run sencha app watch, and navigate to http://localhost:1841/apps/pgrouting/. You should see a similar output (you will have to calculate a route and drive time zone first though):
In order to feed our web app, we need to prepare a web service first. We have gone through creating a nice REST-like API for our WebGIS examples in the previous chapter, so this time all the maintenance stuff is going to be omitted.
At this stage, I assume our barebones web server is up and running, so we just need to plug in some functionality.
In order to perform any routing related logic, we should have the IDs of the vertices we would like to use in our analysis. Let's start...
