This is a template Node.js + Neo4j app, using the
node-neo4j library (available on npm as neo4j).
A demo is running on Heroku at https://node-neo4j-template.herokuapp.com/.
The app is a simple social network manager: it lets you add, remove, follow, and unfollow users. It's basic, and the UI is crappy, but hey, it's a template app. =)
So try it out, browse the code, and fork this project to get a head start on coding your own app. Enjoy!
git clone git@github.com:aseemk/node-neo4j-template.git
cd node-neo4j-template
npm install
You'll also need a local Neo4j 2.x instance.
Install it via neo4j.org/download,
or if you're on a Mac, brew install neo4j.
Start your local Neo4j instance (e.g. neo4j start), then:
npm start
The app will now be accessible at http://localhost:3000/.
To run the tests:
npm test
This app is running on Heroku, using the free version of the GrapheneDB add-on:
https://node-neo4j-template.herokuapp.com/
You can run your own instance similarly for free:
If you prefer to deploy this sample app manually, these are the steps:
heroku create [your-app-name]
heroku addons:add graphenedb
git push heroku master
There's already a Procfile here, and the code already checks for the
necessary PORT and GRAPHENEDB_URL environment variables,
so your deploy should go off without a hitch!
If you're deploying in another way, the code also checks for a NEO4J_URL
environment variable to support pointing to any other Neo4j database.
The value of this variable should be set to the database root URL, and it can
contain HTTP Basic Auth info. E.g. https://user:pass@1.2.3.4:5678.
You can alternately pass the auth portion (user:pass) as NEO4J_AUTH.
One thing to note is that npm start is currently geared towards development:
it runs node-dev instead of node.
Edit scripts.start in package.json if you need to change that.

- As an exercise, I built this without using CoffeeScript or Streamline. What a gigantic pain! Never again. =P
