Another version of the legendary movie database. This time with NodeJS. The app is being deployed to Heroku after every push. Feel free to check it out: http://movie-database-node.herokuapp.com/!

Make sure that you have node.js with NPM installed on your machine. You also need a Neo4j instance listening on http://127.0.0.1:7474.

This project uses a standard node.js module descriptor (package.json) and Grunt as a tool for test execution and static source code analysis. To install the project's dependencies, simply run npm install in the project's root directory. This will make sure that the development tools are locally installed.

To make use of Grunt, you further need to have its CLI tool on your path.

npm install -g grunt-cli

The most useful Grunt tasks currently are simplemocha for test execution and jshint for static source code analysis. To execute these tasks, simple call Grunt:

grunt simplemocha

As mentioned above, Neo4j needs to be running listening on http://127.0.0.1:7474. Apart from this, you also need to enable node auto indexing. Once enabled, nodes' properties will automatically be indexed. You can activate and configure node auto indexing through the file conf/neo4j.properties in your Neo4j directory. The necessary configuration looks like this.

# Enable auto-indexing for nodes, default is false
node_auto_indexing=true

# The node property keys to be auto-indexed, if enabled
node_keys_indexable=id,type,title,name

You will need to restart Neo4j after changing the configuration file. Additionally, you need to create the index once using the Neo4j console. The Neo4j console can be accessed through the web administration interface or using the command line application bin/neo4j-shell.

In the shell, execute the following command to create the node auto index.

index --create node_auto_index -t Node

In case you are wondering why you need to do this: Even though the index is called the auto index, you can only query it after at least one node has been added to the database (which then automatically creates the index) or after you have created it manually. Trying to query the index without fulfilling at least one of the previously mentioned conditions will result in an error.

As much as possible, the application tries to configure automatic indexing at application start through Neo4j's web service.

The code for the server is in the src-folder.

To clear the database, you only need to delete the directory data/graph.db. Please note that you should only do this once Neo4j is shut down (at the very least, Neo4j requires a restart in order to properly work again after deleting the directory). Also, please note that you should create the node auto index after resetting the database (as mentioned above). A convenient way to do this is the following bash script. It needs to be execute in your Neo4j installation directory.

# stop the server, delete the current graph, restart it and create the auto index
sudo /etc/init.d/neo4j-service stop && \
    sudo rm -rf data/graph.db/ && \
    sudo /etc/init.d/neo4j-service start && \
    bin/neo4j-shell -c "index --create node_auto_index -t Node"

Automatically restarting the server on file changes is desirable as this increases your development pace. Supervisor can help you with this.

# To install supervisor
npm install -g supervisor

# Then run the server
supervisor src/server.js
