This is an express.js based webservice starter kit for services connecting to Apache Cassandra™ and/or DataStax Enterprise using the official datastax-driver. This package also includes security-related packages and an example auth table and associated endpoint example.

This is not an official package. It was created by Ryan Weal of Kafei Interactive Inc. (Montréal). Some of the startup code was copied from the killrvideo-nodejs as noted below. As a result, this work is licensed similarly as Apache-2.0.

Install Steps

  1. Clone this repo

    Run npm install to fetch the packages needed to run this package. Install Node.js if you do not have npm.

  2. Populate your environment variables and/or create a variables.env file in this folder:

SECRET='randomwords' # changing this will expire all issued tokens
  1. Remember to create a keyspace, mykeyspace, to start:

    create keyspace mykeyspace with replication = { 'class' : 'SimpleStrategy', 'replication_factor' : 2 } ;

  2. Then run npm run start.


This package makes use of:

  • bcrypt (for auth example)
  • bluebird
  • dotenv (sets environment variables locally, not needed in production if you are being very strict)
  • datastax-driver
  • express.js
  • helmet
  • jsonwebtoken (for auth example)
  • limits
  • node.js
  • validator.js

Some code examples (to establish connections with Cassandra) were copied or derived from: (also license Apache-2.0). Specifically: src/with-retries.js is used unchanged from the original. I modified src/cassandra.js to enable starting the application in a way I think makes the most sense for serverless startup. Support for the logger and etcd was completely dropped for now. Additionally app.js was used as a starting point, maintaining the same startAsync and stop functions in structure but otherwise mapping out to express-related functions at the appropriate times.
