A REST api designed to parse and transverse a public transportation graph and make recommendations on where a person or group of people should live based on supplied parameters. This api will back a commute calculator ui that will supply to the user geometrical definitions of areas of the a city based on various parameters that the user inputs.

Make sure you have:

• Ruby version: 2.3.1

• Rails version: 5

• Java Development Kit: jdk8 (required by neo4j)

With postgres installed, initialize the database with: $ rake db:create $ rake db:migrate

Since this is a less typical setup, and has a few gotchyas I'll cover it in more detail. Download the dmg from the neo4j website then $ brew install neo4j

If you are using zsh you should alias rake or put noglob before each neo4j rake task alias rake='noglob bundle exec rake'

Install the databases for each environment into the project

rake neo4j:install[community-3.1.0,test]
rake neo4j:install[community-3.1.0,development]

Configure and migrate

rake neo4j:config[test,7474]
rake neo4j:config[development,7575]
rake neo4j:disable_auth[development]
rake neo4j:disable_auth[test]

Run the Databases

rake neo4j:start[test]
rake neo4j:start[development]
rake neo4j:migrate:all

You should be able to navigate to http://localhost:7575 or http://localhost:7474 in your browser and see a neo4j ui with a display of any data and basic tutorials.

• Run the server with: rails s and navigate to http://localhost:3001 (The default port is set to 3001 so that a second server can be easily run alongside the api using rails defaults)

• Run the tests with: rspec spec (make sure neo4j and postgres are up and in the proper state)

GTFS

GeoJSON

React based ui (separate repo)

• Services (job queues, cache servers, search engines, etc.) TBD
