Node-Neo4j Template

This is a template app showing the use of Neo4j from Node.js. It uses the node-neo4j library, available on npm as neo4j.

The app is a simple social network manager: it lets you add and remove users and "follows" relationships between them.

This app supports deploying to Heroku, and a demo is in fact running live at http://node-neo4j-template.herokuapp.com/.

So try it out, browse the code, and fork this project to get a head start on creating your own Node-Neo4j app. Enjoy!

Installation

# Install the required dependencies
npm install

# Install a local Neo4j instance
NEO4J_VERSION=neo4j-community-1.9.4
curl http://dist.neo4j.org/$NEO4J_VERSION-unix.tar.gz --O $NEO4J_VERSION-unix.tar.gz
tar -zxvf $NEO4J_VERSION-unix.tar.gz
rm $NEO4J_VERSION-unix.tar.gz
ln -s $NEO4J_VERSION/bin/neo4j neo4j

Usage

# Start the local Neo4j instance
./neo4j start

# Run the app!
npm start

The app will now be accessible at http://localhost:3000/.

The UI is admittedly quite crappy, but hopefully it shows the functionality. (Anyway, this project is really about the code! =P)

Miscellany

  • MIT license.
  • Questions/comments/etc. are welcome.
  • As an exercise, I built this without using CoffeeScript or Streamline. What a gigantic pain! Never again. =P
