Datastax Card Fraud Prevention Demo - Create the RTFAP Node.js/D3 ReST Server

Install Node.js

On my Mac Node I used brew to install node:

$ brew install node

Installs node to /usr/local/Cellar/node/8.9.1/ and sets up link to /usr/local/bin/node

Testing your node and npm installation:

$ node -v
> v8.9.1

$ npm -v
> 5.5.1

Install Express

We can now use npm to install all the Node.js tools needed, including Express.

NPM 1.0 installs modules at the project-level. Command-line tools can be installed globally.

Because Express is a project module and a command line tool we can install it in both scopes, so we will install it globally:

$ npm install -g express
$ npm install -g express-generator
$ express --version
4.15.5

Install Node Cassandra Driver

You will also need to install the Node Cassandra driver to allow the Node web application to communicate with the Cassandra database.

$ npm install cassandra-driver
+ cassandra-driver@3.3.0
updated 2 packages in 12.379s

Test Access and data retrieval

Navigate to the restRTFAP directory in the repo:

$ cd restRTFAP

Note: the Node.js application directory structure in the restRTFAP directory was originally created with Express, using the command $ express restRTFAP.

Start the Node http server using the command DEBUG=restrtfap:* npm start Alternatively use the simple shell script provided ./run.sh

Output is logged to the screen.

Don't exit the terminal session - keep it open for diagnostic output and to preserve the web service.

You should see the console display the following:

> restrtfap@0.0.0 start /Users/johndoe/Documents/My Projects/GitHub/RTFAP2/restRTFAP
> node ./bin/www

  restrtfap:server Listening on port 3000 +0ms

Now go to the service URL: http://localhost:3000/

At this point you will be able to run some (but not all) of the Solr queries.

The web page demonstrates the use of both straightforward CQL queries, and CQL-Solr queries, but the roll-up tables have not been populated yet so these will return no data at this point.

You can find more detailed instructions for installing Node, D3, and jquery using my example at https://github.com/simonambridge/chartDSE
