US-500-Graph Reference Application

This application is an implementation of the exercises prescribed by the WayBlazer Neo4j Candidate Interview.

The dataset used is provided here.

Build

To build the library from source, clone the project from github

[email protected]:jclosure/us-500-graph.git

The source code uses the module style of node (require and module.exports) to organize dependencies. To install all dependencies and build the library, run npm install in the root of the project.

cd us-500-graph
npm install
npm run setup

Usage

Prereqs

Install Neo4j

Example:

brew install neo4j

Setup Neo4j

The examples below are shown using the following credentials for Neo4j

username: neo4j password: admin

Make sure you've logged into your Neo4j server and set your user/pass.

http://localhost:7474

Running the app

In your shell set the NEO4J_URL variable appropriately for your system.

Linux/MacOS:

export NEO4J_URL=http://neo4j:admin@localhost:7474

Windows:

set NEO4J_URL=http://neo4j:admin@localhost:7474

Run the app:

node app.js

Navigate to:

http://localhost:3000

Testing

To test the library, install the project dependencies once:

npm install

Make sure you set the NEO4J_URL env var before running the tests. If you do not, no tests will run.

Then run the tests with:

npm test

You can develop with live testing with grunt-watch by running:

grunt watch
